# Offlineimap sample configuration file

# This file documents *all* possible options and can be quite scary.
# Looking for a quick start?  Take a look at offlineimap.conf.minimal.
# More details can be found at http://www.offlineimap.org .

##################################################
# Overview
##################################################

# The default configuration file is "~/.offlineimaprc".
#
# Offlineimap ships with a file named "offlineimap.conf" that you should copy to
# that location and then edit.
#
# Offlineimap also ships a file named "offlineimap.conf.minimal" that you can
# also try.  It's useful if you want to get started with the most basic feature
# set, and you can read about other features later with "offlineimap.conf".
#
# If you want to be XDG-compatible, you can put your configuration file into
# "$XDG_CONFIG_HOME/offlineimap/config".

##################################################
# General definitions
##################################################

# NOTE 1: Settings generally support python interpolation. This means
# values can contain python format strings which refer to other values
# in the same section, or values in a special DEFAULT section. This
# allows you for example to use common settings for multiple accounts:
#
# [Repository Gmail1]
# trashfolder: %(gmailtrashfolder)s
#
# [Repository Gmail2]
# trashfolder: %(gmailtrashfolder)s
#
# [DEFAULT]
# gmailtrashfolder = [Gmail]/Papierkorb
#
# would set the trashfolder setting for your German Gmail accounts.

# NOTE 2: Above feature implies that any '%' needs to be encoded as '%%'

# NOTE 3: Any variable that is subject to the environment variables
# ($NAME) and tilde (~username/~) expansions will receive tilde
# expansion first and only after the environment variable will be
# expanded in the resulting string. This behaviour is intentional
# as it coincides with typical shell expansion strategy.

# NOTE 4: multiple same-named sections.
# The library used to parse the configuration file has known issue when multiple
# sections have the same name. In such case, only the last section is considered.
# It is strongly discouraged to have multiple sections with the same name.
# See https://github.com/OfflineIMAP/offlineimap/issues/143 for more details.

[general]

# This specifies where Offlineimap is to store its metadata.
# This directory will be created if it does not already exist.
#
# Tilde and environment variable expansions will be performed.
#
#metadata = ~/.offlineimap


# This option stands in the [general] section.
#
# This variable specifies which accounts are defined. Separate them with commas.
# Account names should be alphanumeric only. You will need to specify one
# section per account below. You may not use "general" for an account name.
#
# Always use ASCII characters only.
#
accounts = Test


# This option stands in the [general] section.
#
# Offlineimap can synchronize more than one account at a time. There are two
# ways to sync accounts concurrently:
#
# 1. By running one offlineimap instance for each account (with the -a CLI
# option). This is the recommended way. In this case, keep the following option
# to 1.
#
# 2. By allowing offlineimap to sync more than one account for an instance (not
# recommended). In this case, set the maxsyncaccounts option to a value greater
# than 1.
#
#maxsyncaccounts = 1


# This option stands in the [general] section.
#
# You can specify one or more user interface. Offlineimap will try the first in
# the list, and if it fails, the second, and so forth.
#
# The pre-defined options are:
# Blinkenlights -- A fancy (terminal) interface
# TTYUI         -- a text-based (terminal) interface
# Basic         -- Noninteractive interface suitable for cron'ing
# Quiet         -- Noninteractive interface, generates no output
#                  except for errors.
# MachineUI     -- Interactive interface suitable for machine
#                  parsing.
#
# See also offlineimapui(7)
#
# You can override this with a command-line option -u.
#
ui = Blinkenlights


# This option stands in the [general] section.
#
# If you try to synchronize messages to a folder which the IMAP server
# considers read-only, Offlineimap will generate a warning.  If you want
# to suppress these warnings, set ignore-readonly to yes.  Read-only
# IMAP folders allow reading but not modification, so if you try to
# change messages in the local copy of such a folder, the IMAP server
# will prevent Offlineimap from propagating those changes to the IMAP
# server.  Note that ignore-readonly is UNRELATED to the "readonly"
# setting which prevents a repository from being modified at all.
#
#ignore-readonly = no


########## Advanced settings

# This option stands in the [general] section.
#
# You can give a Python source filename here and all config file
# python snippets will be evaluated in the context of that file.
# This allows you to e.g. define helper functions in the Python
# source file and call them from this config file.  You can find
# an example of this in the manual.
#
# Tilde and environment variable expansions will be performed.
#
#pythonfile = ~/.offlineimap.py


# This option is in the [general] section.
#
# By default, Offlineimap will not exit due to a network error until the
# operating system returns an error code.  Operating systems can sometimes take
# forever to notice this.  Here you can activate a timeout on the socket.  This
# timeout applies to individual socket reads and writes, not to an overall sync
# operation.  You could perfectly well have a 30s timeout here and your sync
# still take minutes.
#
# Values in the 30-120 second range are reasonable.
#
# The default is to have no timeout beyond the OS.  Times are given in seconds.
#
#socktimeout = 60


# This option stands in the [general] section.
#
# By default, Offlineimap will use fsync() to force data out to disk at
# opportune times to ensure consistency.  This can, however, reduce performance.
# Users where /home is on SSD (Flash) may also wish to reduce write cycles.
# Therefore, you can disable Offlineimap's use of fsync().  Doing so will come
# at the expense of greater risk of message duplication in the event of a system
# crash or power loss.  Default is true.  Set it to false to disable fsync.
#
# SQLite honors this option since v7.0.8+. However, those SQLite improvements
# are still EXPERIMENTAL.
#
#fsync = true


##################################################
# Mailbox name recorder
##################################################

[mbnames]

# Offlineimap can record your mailbox names in a format you specify.
# You can define the header, each mailbox item, the separator,
# and the footer.  Here is an example for Mutt.
# If enabled is yes, all settings except incremental must be specified, even if
# they are just the empty string "".
#
# The header, peritem, sep, and footer are all Python expressions passed
# through eval, so you can (and must) use Python quoting.
#
# The incremental setting controls whether the file is written after each
# account completes or once all synced accounts are complete. This is useful if
# an account is sightly slower than the other. It allows keeping the previous
# file rather than having it partially written.
# This works best with "no" if in one-shot mode started by cron or systemd
# timers. Default: no.
#
# The following hash key are available to the expansion for 'peritem':
# - accountname: the name of the corresponding account;
# - foldername: the name of the folder;
# - localfolders: path to the local directory hosting all Maildir
#   folders for the account.
#
# Tilde and environment variable expansions will be performed
# for "filename" knob.
#
enabled = yes
filename = ~/.mutt/mailboxes
header = "mailboxes "
peritem = "+%(accountname)s/%(foldername)s"
sep = " "
footer = "\n"
incremental = no


# This option stands in the [mbnames] section.
#
# You can also specify a folderfilter.  It will apply to the *translated* folder
# name here, and it takes TWO arguments: accountname and foldername.  In all
# other ways, it will behave identically to the folderfilter for accounts.
# Please see the folderfilter option for more information and examples.
#
# This filter can be used only to further restrict mbnames to a subset of
# folders that pass the account's folderfilter.
#
# E.g.: with mbnames_folderfilter defined like this in the python file:
#
# def mbnames_folderfilter(accountname, foldername):
#     allowed = {'myaccount': ['folderA', 'folderB']}
#     if accountname in allowed:
#         return foldername in allowed[accountname]
#     return False
#
# For correct folderfilter with Microsoft servers, please see
# http://www.offlineimap.org/doc/FAQ.html#exchange-and-office365
#
#folderfilter = mbnames_folderfilter


# This option stands in the [mbnames] section.
#
# You can customize the order in which mailbox names are listed in the generated
# file by specifying a sort_keyfunc, which takes a single dict argument
# containing keys 'accountname' and 'foldername'.  This function will be called
# once for each mailbox, and should return a suitable sort key that defines this
# mailbox' position in the custom ordering.
#
# This is useful with e.g. Mutt-sidebar, which uses the mailbox order from the
# generated file when listing mailboxes in the sidebar.
#
# Default setting is:
#sort_keyfunc = lambda d: (d['accountname'], d['foldername'])


##################################################
# Accounts
##################################################

# This is an account definition clause.  You'll have one of these for each
# account listed in the "accounts" option in [general] section (above).

[Account Test]

# These settings specify the two folders that you will be syncing.
# You'll need to have a "Repository ..." section for each one.

localrepository = LocalExample

########## Advanced settings

# This option stands in the [Account Test] section.
#
# You can have Offlineimap continue running indefinitely, automatically syncing
# your mail periodically.  If you want that, specify how frequently to do that
# (in minutes) here.  Fractional minutes (ie, 3.25) is allowed.
#
# If you want more than one account concurrently synced in one instance of
# offlineimap (not recommended), don't forget to increase the maxsyncaccounts
# option accordingly.
#
# NOTE: If you run systemd it's recommended to not enable this option and use
# the systemd timer instead (see the ./contrib/systemd/ directory in the
# repository).
#
#autorefresh = 5


# This option stands in the [Account Test] section.
#
# OfflineImap can replace a number of full updates by quick synchronizations.
# This option is ignored if maxage or startdate are used.
#
# It only synchronizes a folder if
#
#   1) a Maildir folder has changed
#
# or
#
#   2) if an IMAP folder has received new messages or had messages deleted, ie
#   it does not update if only IMAP flags have changed.
#
# Full updates need to fetch ALL flags for all messages, so this makes quite a
# performance difference (especially if syncing between two IMAP servers).
#
# Specify 0 for never, -1 for always (works even in non-autorefresh mode)
#
# A positive integer <n> to do <n> quick updates before doing another full
# synchronization (requires autorefresh).  Updates are always performed after
# <autorefresh> minutes, be they quick or full.
#
#quick = 10


# This option stands in the [Account Test] section.
#
# You can specify a pre and post sync hook to execute a external command.  In
# this case a call to imapfilter to filter mail before the sync process starts
# and a custom shell script after the sync completes.
#
# The pre sync script has to complete before a sync to the account will start.
#
#presynchook = imapfilter -c someotherconfig.lua
#postsynchook = notifysync.sh


# This option stands in the [Account Test] section.
#
# If you have a limited amount of bandwidth available you can exclude larger
# messages (e.g. those with large attachments etc).  If you do this it will
# appear to Offlineimap that these messages do not exist at all.  They will not
# be copied, have flags changed etc.  For this to work on an IMAP server the
# server must have server side search enabled.  This works with Gmail and most
# imap servers (e.g. cyrus etc)
#
# The maximum size should be specified in bytes - e.g. 2000000 for approx 2MB
#
#maxsize = 2000000


# This option stands in the [Account Test] section.
#
# maxage enables you to sync only recent messages. There are two ways to specify
# what "recent" means: if maxage is given as an integer, then only messages from
# the last maxage days will be synced. If maxage is given as a date, then only
# messages later than that date will be synced.
#
# Messages older than the cutoff will not be synced, their flags will not be
# changed, they will not be deleted, etc. For Offlineimap it will be like these
# messages do not exist. This will perform an IMAP search in the case of IMAP or
# Gmail and therefore requires that the server support server side searching.
#
# Known edge cases are described in offlineimap(1).
#
# maxage is allowed only when the local folder is of type Maildir. It can't be
# used with startdate.
#
# The maxage option expects an integer (for the number of days) or a date of the
# form yyyy-mm-dd.
#
#maxage = 3
#maxage = 2015-04-01


# This option stands in the [Account Test] section.
#
# Maildir file format uses colon (:) separator between uniq name and info.
# Unfortunately colon is not allowed character in windows file name. If you
# enable maildir-windows-compatible option, Offlineimap will be able to store
# messages on windows drive, but you will probably loose compatibility with
# other programs working with the maildir.
#
#maildir-windows-compatible = no


# This option stands in the [Account Test] section.
#
# Specifies if we want to sync GMail labels with the local repository.
# Effective only for GMail IMAP repositories.
#
# Non-ASCII characters in labels are bad handled or won't work at all.
#
#synclabels = no


# This option stands in the [Account Test] section.
#
# Name of the header to use for label storage.  Format for the header
# value differs for different headers, because there are some de-facto
# "standards" set by popular clients:
#
# - X-Label or Keywords keep values separated with spaces; for these
#   you, obviously, should not have label values that contain spaces;
#
# - X-Keywords use comma (',') as the separator.
#
# To be consistent with the usual To-like headers, for the rest of header
# types we use comma as the separator.
#
# Use ASCII characters only.
#
#labelsheader = X-Keywords


# This option stands in the [Account Test] section.
#
# Set of labels to be ignored.  Comma-separated list.  GMail-specific
# labels all start with backslash ('\').
#
# Use ASCII characters only.
#
#ignorelabels = \Inbox, \Starred, \Sent, \Draft, \Spam, \Trash, \Important


# This option stands in the [Account Test] section.
#
# Offlineimap can strip off some headers when your messages are propagated
# back to the IMAP server.  This option carries the comma-separated list
# of headers to trim off.  Header name matching is case-sensitive.
#
# This knob is respected only by IMAP-based accounts.  Value of labelsheader
# for GMail-based accounts is automatically added to this list, you don't
# need to specify it explicitly.
#
# Use ASCII characters only.
#
#filterheaders = X-Some-Weird-Header


# This option stands in the [Account Test] section.
#
# Use proxy connection for this account. Useful to bypass the GFW in China.
# To specify a proxy connection, join proxy type, host and port with colons.
# Available proxy types are SOCKS5, SOCKS4, HTTP.
# You also need to install PySocks through pip.
#
# Currently, this feature leaks DNS support.
#
#proxy = SOCKS5:IP:9999


# EXPERIMENTAL: This option stands in the [Account Test] section.
#
# IMAP defines an encoding for non-ASCII ("international") characters, and most
# IMAP servers store folder names in this encoding. Note that the IMAP 4rev1
# specification (RFC 3501) allows both UTF-8 and modified UTF-7 folder names
# so it is *possible* that an IMAP server already uses UTF-8 encoded folder
# names. But usually Folders that are shown as, say, "Gäste" will be represented
# as "G&AOQ-ste", and by default will be synchronized like this by offlineIMAP.
#
# This option converts IMAP folder names from IMAP4-UTF-7 to UTF-8 and back
# in order to have nicely readable UTF-8 folder names in the local copy.
#
# WARNING: with this option enabled:
# - compatibility with any other version is NOT GUARANTEED (including newer);
# - existing set-ups will probably break.
# - no support is provided.
#
# IMPORTANT: READ THIS SECTION if you intend to enable this feature for an
# EXISTING ACCOUNT that has already been synchronized!
# Enabling UTF-8 encoded folder names will change many things on the local
# repository of an account, so you really have to create a new local repository
# and review the configuration. The least that would happen otherwise is a
# duplication of all folders containing non-ASCII characters.
# But also the following functionality may change, so the configuration in the
# remote repository configuration has to be reviewed/updated:
# - decodefoldernames
#   This option is replaced by utf8foldernames and must be removed
#   If both utf8foldernames and decodefoldernames are enabled the synchronization
#   for the given account is aborted before doing any changes.
# - nametrans
#   With utf8foldernames enabled any nametrans function will operate on the
#   UTF-8 encoded folder names, while even with decodefoldernames enabled they
#   operate on the original IMAP4-UTF-7 encoded names.
# - folderfilter
#   Folder filters still work on the untranslated names before applying a
#   nametrans function, but still this operates on the UTF-8 encoded names.
# - folderincludes
#   With utf8foldernames enabled this function expects UTF-8 encoded folder
#   names.
# - foldersort
#   With utf8foldernames enabled the folder names passed to the sorting routine
#   will be the UTF encoded names.
# - idlefolders
#   With utf8foldernames enabled folders passed to this function are expected to
#   be UTF-8 encoded.
#
utf8foldernames = yes


# TESTING: This option stands in the [Account Test] section.
#
# Use authproxy connection for this account. Useful to bypass the GFW in China.
# Set this if you wish to use a proxy for authentication but not for IMAP.
# If not explicitly set, this option defaults to use the proxy socket
# (so as to be compatible with prior config files).
# If that is specifically NOT desired, use authproxy = ''
#
# To specify a proxy connection, join proxy type, host and port with colons.
# Available proxy types are SOCKS5, SOCKS4, HTTP.
# You also need to install PySocks through pip or your distro package manager.
#
#authproxy = SOCKS5:IP:9999

# This option stands in the [Repository LocalExample] section.
#
# You can specify the "folder separator character" used for your Maildir
# folders.  It is inserted in-between the components of the tree. If you

# Otherwise, default value is ".".
#
# Don't use quotes.
#

# This option stands in the [Repository LocalExample] section.
#
# startdate syncs mails starting from a given date. It applies the date
# restriction to LocalExample only. The remote repository MUST be empty
# at the first sync where this option is used.
#
# Unlike maxage, this is supported for IMAP-IMAP sync.

#startdate = 2015-04-01


# This option stands in the [Repository LocalExample] section.
#
# Propagate deletions from local to remote. Messages deleted in this repository

#
#sync_deletes = yes


# This option stands in the [Repository LocalExample] section.
#
# Some users may not want the atime (last access time) of folders to be
# modified by Offlineimap.  If 'restoreatime' is set to yes, Offlineimap

#
# In nearly all cases, the default should be fine.
#
#restoreatime = no


# This option stands in the [Repository LocalExample] section.
#
# Set modification time of messages basing on the message's "Date" header. This
# option makes sense for the Maildir type, only.
#
# This is useful if you are doing some processing/finding on your Maildir (for
# example, finding messages older than 3 months), without parsing each
# file/message content.
#
# This option is not compatible with -q (quick mode) CLI option for GmailMaildir
# types.
#
# Default: no.
#
#utime_from_header = no


# This option stands in the [Repository LocalExample] section.
#
# This option is similar to "utime_from_header" and could be used as a
# complementary feature to keep track of a message date. This option only
# makes sense for the Maildir type.
#
# By default each message is stored in a file which prefix is the fetch
# timestamp and an order rank such as "1446590057_0". In a multithreading
# environment message are fetched in a random order, then you can't trust
# the filename to sort your boxes.
#
# If set to "yes" the filename prefix is built from the message "Date" header
# (which should be present) or the "Received-date" if "Date" is not
# found. If neither "Received-date" nor "Date" is found, the current system
# date is used.  Now you can quickly sort your messages using their filenames.
#
# Used in combination with "utime_from_header" all your message would be in
# order with the correct mtime attribute.
#
#filename_use_mail_timestamp = no


# This option stands in the [Repository LocalExample] section.

#
# Configuration example:
#      customflag_x = some_keyword
#
# With the configuration example above enabled, all IMAP messages that have
# 'some_keyword' in their FLAGS field will have an 'x' in the flags part of the
# maildir filename:
#      1234567890.M20046P2137.mailserver,S=4542,W=4642:2,Sx

[Repository GmailLocalExample]

# This type of repository enables syncing of Gmail. All Maildir
# configuration settings are also valid here but the utime_from_header.
#
# This is a separate Repository type from Maildir because it involves
# some extra overhead which sometimes may be significant.  We look for
# modified tags in local messages by looking only to the files
# modified since last run.  This is usually rather fast, but the first

# Whether or not to use STARTTLS. STARTTLS allows to upgrade a plain connection
# to TLS or SSL after negotiation with the server. While a server might pretend
# to support STARTTLS, the communication might not be properly established or

# disable STARTTLS. Unless you hit issues with STARTTLS, you are strongly
# encouraged to keep STARTTLS enabled.

# This option stands in the [Repository RemoteExample] section.
#
# Whether or not to use SSL.
#
# Note: be care to configure the 'remotehost' line with the domain name defined
# in the certificate. E.g., if you trust your provider and want to use the
# certificate it provides on a shared server. Otherwise, Offlineimap will stop
# and say that the domain is not named in the certificate.
#
# Default is yes.

#sslclientkey = /path/to/file.key


# This option stands in the [Repository RemoteExample] section.
#
# SSL CA Cert(s) to verify the server cert against (optional).
# No SSL verification is done without this option. If it is
# specified, the CA Cert(s) need to verify the Server cert AND
# match the hostname (* wildcard allowed on the left hand side)
# The certificate should be in PEM format.
#
# Tilde and environment variable expansions will be performed.
#
# Special value OS-DEFAULT makes Offlineimap to automatically
# determine system-wide location of standard trusted CA roots file
# for known OS distributions and use the first bundle encountered
# (if any).  If no system-wide CA bundle is found, Offlineimap
# will refuse to continue; this is done to prevent creation
# of false security expectations ("I had configured CA bundle,
# thou certificate verification shalt be present").
#
# You can also use fingerprint verification via cert_fingerprint.
# See below for more verbose explanation.
#
#sslcacertfile = /path/to/cacertfile.crt


# This option stands in the [Repository RemoteExample] section.
#
# If you connect via SSL/TLS (ssl = yes) and you have no CA certificate
# specified, Offlineimap will refuse to sync as it connects to a server
# with an unknown "fingerprint". If you are sure you connect to the
# correct server, you can then configure the presented server
# fingerprint here. Offlineimap will verify that the server fingerprint
# has not changed on each connect and refuse to connect otherwise.
#
# You can also configure fingerprint validation in addition to
# CA certificate validation above and it will check both:
# Offlineimap fill verify certificate first and if things will be fine,
# fingerprint will be validated.
#
# Multiple fingerprints can be specified, separated by commas.
#
# In Windows, Microsoft uses the term "thumbprint" instead of "fingerprint".
#
# Supported fingerprint hashes are sha512, sha384, sha256, sha224 and sha1.
# Fingerprints must be in hexadecimal form without leading '0x', and may have
# the separating colons. This is non case-sensitive.

# Set SSL version to use (optional).
#
# It is best to leave this unset, in which case the correct version will be

# particular version from: tls1, tls1_1, tls1_2, ssl3, ssl23.
#
# tls1_1 and tls1_2 are available with OpenSSL since v1.0.1.
#
# ssl23 automatically selects the highest protocol version that both the client
# and server support.  Despite the name, this option can select “TLS” protocols
# as well as “SSL”.
#
# Be aware that a MITM attack can consist in downgrading the protocol version
# which is used upon client/server agreement. So, they might fallback to the
# less secure available protocol. Hence, it is considered more safe to manually
# define the protocol version.
#
# See the configuration option tls_level to disable insecure protocols.

# XOAUTH2 authentication (for instance, to use with Gmail).
#
# This option was tested on Gmail only, but should work with type = IMAP for
# compatible servers.
#
# For Gmail (and maybe others), XOAUTH2 requires ssl. This means that STARTTLS
# won't work and that Offlineimap will perform certificate validation.  IOW, the
# following configuration is used:
#   - sslcacertfile: MUST BE correctly configured
#   - ssl = yes (optional, will be used anyway)
#   - starttls = no (optional, will be tried but won't work anyway)
#
# Mandatory parameters are "oauth2_client_id", "oauth2_client_secret" and
# either "oauth2_refresh_token" or "oauth2_access_token". XOAUTH2 mechanism
# won't be tried if both oauth2_refresh_token and oauth2_access_token are not
# set.
#
# See below to learn how to get those.
#
# Specify the OAuth2 client id and secret to use for the connection..
# Here's how to register an OAuth2 client for Gmail, as of 2017-05-15:
#    - Go to the Gmail API overview console
#         https://console.developers.google.com/apis/api/gmail.googleapis.com/overview
#    - Create a new project, name doesn't matter, e.g. 'gmail-sync-bob'
#    - In API & Auth, select Credentials
#    - Once created, click 'Enable'
#    - Click 'Create credentials' in the enabled API overview

#    - In 'Add credentials to your project' select 'Gmail API' as the
#      API type, and 'Other UI ...' (not 'Other non-UI ...') for
#      'Where will you be calling the API from?'. For 'What data will
#      you be accessing?' select 'User data'.
#    - Click 'What credentials do I need?'
#    - Create an arbitrary 'Create an OAuth 2.0 client ID',
#      e.g. 'gmail-sync-bob-client'. For 'Set up the OAuth 2.0 consent
#      screen' select an arbitrary 'Product name shown to users',
#      e.g. 'gmail-sync-bob-client' & click 'Continue'.
#    - This gives  you your client  ID displayed on the  screen. Click
#      'Download' to get a JSON file that also has the client secret.
#
#oauth2_client_id = YOUR_CLIENT_ID
#oauth2_client_secret = YOUR_CLIENT_SECRET
#
# The return values must be bytes.
#oauth2_client_id_eval = get_client_id("accountname")
#oauth2_client_secret_eval = get_client_secret("accountname")
#
# Specify the refresh token to use for the connection to the mail server.
# Here's an example of a way to get a refresh token:
#    - Clone this project: https://github.com/google/gmail-oauth2-tools
#    - Type the following command-line in a terminal and follow the instructions
#         python python/oauth2.py --generate_oauth2_token \
#            --client_id=YOUR_CLIENT_ID --client_secret=YOUR_CLIENT_SECRET
#    - Access token can be obtained using refresh token with command
#         python python/oauth2.py --user=YOUR_EMAIL --client_id=YOUR_CLIENT_ID
#            --client_secret=YOUR_CLIENT_SECRET --refresh_token=REFRESH_TOKEN
#
# Access tokens have limited lifetimes. If you need access beyond the lifetime
# of a single access token, you should use a refresh token. A refresh token
# allows Offlineimap to obtain new access tokens.
#
# If you want to use a refresh token, make sure you disabled/removed any
# oauth2_access_token option. The access token is downloaded from the URL
# defined in the oauth2_request_url configuration option.
#
# If the type of the remote is IMAP, oauth2_request_url MUST be defined.
# For Gmail, the default URL is https://accounts.google.com/o/oauth2/token.
#
# If you're experiencing issues, please read the "Known issues" section of the
# manual.
#
#oauth2_access_token = ACCESS_TOKEN
#oauth2_request_url = https://accounts.google.com/o/oauth2/token
#oauth2_refresh_token = REFRESH_TOKEN
#
# The returned values must be bytes.
#oauth2_access_token_eval = get_access_token("accountname")
#oauth2_refresh_token_eval = get_refresh_token("accountname")

########## Passwords

# There are six ways to specify the password for the IMAP server:
#
# 1. No password at all specified in the config file.
#    If a matching entry is found in ~/.netrc (see netrc (5) for
#    information) this password will be used. Do note that netrc only
#    allows one entry per hostname. If there is no ~/.netrc file but
#    there is an /etc/netrc file, the password will instead be taken
#    from there. Otherwise you will be prompted for the password when
#    Offlineimap starts when using a UI that supports this.
#
# 2. The remote password stored in this file with the remotepass
#    option. Save this file with the UTF-8 encoding if your server expect UTF-8
#    encoded password.
#
#    Any '%' needs to be encoded as '%%'. Example:
remotepass = AAAAAAAAA
#
# 3. The remote password stored as a single line in an external file, which is
#    referenced by the remotefile option. Must be UTF-8 encoded. Example:
#remotepassfile = ~/Password.IMAP.Account1
#
# 4. With a preauth tunnel.  With this method, you invoke an external
#    program that is guaranteed *NOT* to ask for a password, but rather
#    to read from stdin and write to stdout an IMAP protocol stream that
#    begins life in the PREAUTH state.  When you use a tunnel, you do
#    NOT specify a user or password (if you do, they'll be ignored.)
#    Instead, you specify a preauthtunnel, as this example illustrates
#    for Courier IMAP on Debian:
#preauthtunnel = ssh -q imaphost '/usr/bin/imapd ./Maildir'
#
# 5. If you are using Kerberos and have the Python gssapi package
#    installed, you should not specify a remotepass.  If the user has a
#    valid Kerberos TGT, Offlineimap will figure out the rest all by
#    itself, and fall back to password authentication if needed.
#
# 6. Using arbitrary python code.  With this method, you invoke a
#    function from your pythonfile.  To use this method assign the name
#    of the function to the variable 'remotepasseval'.  Example:
#remotepasseval = get_password("imap.example.net")
#    You can also query for the username:
#remoteusereval = get_username("imap.example.net")
#    This method can be used to design more elaborate setups, e.g. by
#    querying the gnome-keyring via its python bindings.


########## Advanced settings


# These options stands in the [Repository RemoteExample] section.
#
# Tunnels. There are two types:
#
# - preauth: they teleport your connection to the remote system
#   and you don't need to authenticate yourself there; the sole
#   fact that you succeeded to get the tunnel running is enough.
#   This tunnel type was explained above in the 'Passwords' section.
#
# - transport: the just provide the transport (probably encrypted)
#   to the IMAP server, but you still need to authenticate at the
#   IMAP server.
#
# Tunnels are currently working only with IMAP servers and their
# derivatives (GMail currently).  Additionally, for GMail accounts
# preauth tunnel settings are ignored: we don't believe that there
# are ways to preauthenticate at Google mail system IMAP servers.
#
# You must choose at most one tunnel type, be wise M'Lord!
#
#preauthtunnel = ssh -q imaphost '/usr/bin/imapd ./Maildir'
#transporttunnel = openssl s_client -host myimap -port 993 -quiet


# This option stands in the [Repository RemoteExample] section.
#
# Some IMAP servers need a "reference" which often refers to the "folder root".
#
# This is most commonly needed with UW IMAP, where you might need to specify the
# directory in which your mail is stored. The 'reference' value will be prefixed
# to all folder paths referring to that repository. E.g. accessing folder 'INBOX'
# with "reference = Mail" will try to access Mail/INBOX.
#
# The nametrans and folderfilter functions will apply to the full path,
# including the reference prefix.  Most users will not need this.
#
#reference = Mail


# DEPRECATED: This option stands in the [Repository RemoteExample] section.
#
# IMAP defines an encoding for non-ASCII ("international") characters. Enable
# this option if you want to decode them to the nowadays ubiquitous UTF-8.
#
# Note that the IMAP 4rev1 specification (RFC 3501) allows both UTF-8 and
# modified UTF-7 folder names.
#
# This option converts IMAP folder names from IMAP4-UTF-7 to UTF-8.
#
# NOTE/LIMITATION:
# - The reencoding is applied *after* a nametrans function that may be given,
#   so it is important to note that nametrans will work on the undecoded
#   UTF-7 names.
# - This option only works from a remote IMAP to a local Maildir repository
# - It only works *once*, so it can only be used for one-off backups
#   (see https://github.com/OfflineIMAP/offlineimap/issues/299 and especially
#   https://github.com/OfflineIMAP/offlineimap/issues/299#issuecomment-331243827)
#
# WARNING: with this option enabled:
# - compatibility with any other version is NOT GUARANTED (including newer);

#
# DEPRECATION:
# This option is only there for backward compatibility with existing set-ups.
# For newly created accounts please use the utf8foldernames option on account

#
# This feature was merged because it's small changes in the code.  However, this
# might seriously decrease the stability of the program. That's why it will
# likely never be marked stable. The approach is: if it works for you, you're
# lucky and you might choose to go for it. If it doesn't, sorry but this feature
# is known to not work in many cases and it's not available to you.  Enabling
# this feature might really be a poor choice for the future since it's not
# supported at all and new releases might break the setup.

# This option stands in the [Repository RemoteExample] section.
#
# In between synchronisations, Offlineimap can monitor mailboxes for new
# messages using the IDLE command. If you want to enable this, specify here the
# folders you wish to monitor. IMAP protocol requires a separate connection for
# each folder monitored in this way, so setting this option will force settings
# for:
#
#  - maxconnections: to be at least the number of folders you give
#  - holdconnectionopen: to be true
#  - keepalive: to be 29 minutes unless you specify otherwise
#  - singlethreadperfolder: to be true
#
# The presynchook and postsynchook are executed for each new synchronisation per
# folder.
#
# This feature isn't complete and may well have problems. See the "Known Issues"
# entry in the manual for more details.
#
# This option should return a Python list. For example
#
#idlefolders = ['INBOX', 'INBOX.Alerts']

# Offlineimap can use a compressed connection to the IMAP server.
# This can result in faster downloads for some cases.
#
#usecompression = yes


# This option stands in the [Repository RemoteExample] section.
#
# Offlineimap can use multiple connections to the server in order
# to perform multiple synchronization actions simultaneously.
# This may place a higher burden on the server.  In most cases,
# setting this value to 2 or 3 will speed up the sync, but in some
# cases, it may slow things down.  The safe answer is 1.  You should
# probably never set it to a value more than 5.
#
#maxconnections = 2


# This option stands in the [Repository RemoteExample] section.
#
# If you want to ensure that only one single thread is used to synchronize each
# folder, set this to 'yes'. If this is set, only one thread will be used to
# copy messages for each folder, but up to maxconnections threads will be used
# overall, copying different folders in parallel. This option is required to
# download in UIDs order.
#
# If this is unset (the default), then up to maxconnections threads are used
# across all currently syncing folders. This option is sightly recommended in
# IMAP/IMAP mode (no maildir).
#
#singlethreadperfolder = no


# This option stands in the [Repository RemoteExample] section.
#
# Offlineimap normally closes IMAP server connections between refreshes if
# the global option autorefresh is specified.  If you wish it to keep the
# connection open, set this to true.  If not specified, the default is
# false.  Keeping the connection open means a faster sync start the
# next time and may use fewer server resources on connection, but uses
# more server memory.  This setting has no effect if autorefresh is not set.
#
#holdconnectionopen = no


# This option stands in the [Repository RemoteExample] section.
#
# If you want to have "keepalives" sent while waiting between syncs, specify the
# amount of time IN SECONDS between keepalives here.  Note that sometimes more

# no effect if autorefresh and holdconnectionopen are not both set.
#
#keepalive = 60


# This option stands in the [Repository RemoteExample] section.
#
# Normally, Offlineimap will expunge deleted messages from the server.  You can
# disable that if you wish.  This means that Offlineimap will mark them deleted
# on the server, but not actually delete them.  You must use some other IMAP
# client to delete them if you use this setting; otherwise, the messages will
# just pile up there forever.  Therefore, this setting is definitely NOT
# recommended for a long term.
#
# Default is yes.
#
#expunge = no


# This option stands in the [Repository RemoteExample] section.
#
# Specify whether to process all mail folders on the server, or only
# those listed as "subscribed".
#
# Default is no.

# This option stands in the [Repository RemoteExample] section.
#
# You can specify a folder translator.  This must be a eval-able.
#
# Python expression that takes a foldername arg and returns the new value. A
# lambda function is suggested.
#
# WARNING: you MUST construct it so that it NEVER returns the same value for two
# folders, UNLESS the second values are filtered out by folderfilter below.
# Failure to follow this rule will result in undefined behavior.
#
# If you enable nametrans, you will likely need to set the reversed nametrans on
# the other side. See the user documentation for details and use cases. They
# are also online at: http://www.offlineimap.org/doc/nametrans.html
#
# This example below will remove "INBOX." from the leading edge of folders
# (great for Courier IMAP users).
#
#nametrans = lambda foldername: re.sub('^INBOX\.', '', foldername)

# This option stands in the [Repository RemoteExample] section.
#
# You can specify which folders to sync using the folderfilter setting. You can
# provide any python function (e.g. a lambda function) which will be invoked for
# each foldername. If the filter function returns True, the folder will be

#
# The folderfilter operates on the *UNTRANSLATED* name (before any nametrans
# translation takes place).
#
# Example 1: synchronizing only INBOX and Sent.

# 'foldersort' determines how folders are sorted.

# This affects order of synchronization and mbnames. The expression should
# return -1, 0, or 1, as the default Python cmp() does.  The two arguments, x
# and y, are strings representing the names of the folders to be sorted.  The
# sorting is applied *AFTER* nametrans, if any.  The default is to sort IMAP
# folders alphabetically (case-insensitive). Usually, you should never have to

#
# Notice that this does NOT mean that the local Maildir can be used with a

# Any configuration parameter of "IMAP" type repositories can be used here.
# Only "remoteuser" (or "remoteusereval" ) is mandatory.  Default values for
# other parameters are OK, and you should not need fiddle with those.
#
# The Gmail repository provides default values for "remotehost",
# "remoteport", "tunnel" and "ssl". For the defaults we use, see:
#
#  http://mail.google.com/support/bin/answer.py?answer=78799&topic=12814
#
# This means ssl is enabled and must be configured correctly when connecting to
# Gmail.
#
# In addition we provide defaults for "oauth2_request_url",
# "trashfolder" and "spamfolder".
#
# All of the defaults we provide can be overriden. E.g. you can
# override "remotehost"/"remoteport"/"ssl" if you'd like to connect to
# imap.gmail.com via a local stunnel instead of directly.
#
# To enable GMail labels synchronisation, set the option "synclabels" in the
