## IMAP specific settings
##
# If nothing happens for this long while client is IDLEing, move the connection
# to imap-hibernate process and close the old imap process. This saves memory,
# because connections use very little memory in imap-hibernate process. The
# downside is that recreating the imap process back uses some resources.
#imap_hibernate_timeout = 0
# Maximum IMAP command line length. Some clients generate very long command
# lines with huge mailboxes, so you may need to raise this if you get
# "Too long argument" or "IMAP command line too large" errors often.
#imap_max_line_length = 64k
# IMAP logout format string:
# %i - total number of bytes read from client
# %o - total number of bytes sent to client
# %{fetch_hdr_count} - Number of mails with mail header data sent to client
# %{fetch_hdr_bytes} - Number of bytes with mail header data sent to client
# %{fetch_body_count} - Number of mails with mail body data sent to client
# %{fetch_body_bytes} - Number of bytes with mail body data sent to client
# %{deleted} - Number of mails where client added \Deleted flag
# %{expunged} - Number of mails that client expunged
# %{trashed} - Number of mails that client copied/moved to the
# special_use=\Trash mailbox.
#imap_logout_format = in=%i out=%o
# Override the IMAP CAPABILITY response. If the value begins with '+',
# add the given capabilities on top of the defaults (e.g. +XFOO XBAR).
#imap_capability =
# How long to wait between "OK Still here" notifications when client is
# IDLEing.
#imap_idle_notify_interval = 2 mins
imap_idle_notify_interval = 29 mins
# ID field names and values to send to clients. Using * as the value makes
# Dovecot use the default value. The following fields have default values
# currently: name, version, os, os-version, support-url, support-email.
#imap_id_send =
# ID fields sent by client to log. * means everything.
#imap_id_log =
# Workarounds for various client bugs:
# delay-newmail:
# Send EXISTS/RECENT new mail notifications only when replying to NOOP
# and CHECK commands. Some clients ignore them otherwise, for example OSX
# Mail (<v2.1). Outlook Express breaks more badly though, without this it
# may show user "Message no longer in server" errors. Note that OE6 still
# breaks even with this workaround if synchronization is set to
# "Headers Only".
# tb-extra-mailbox-sep:
# Thunderbird gets somehow confused with LAYOUT=fs (mbox and dbox) and
# adds extra '/' suffixes to mailbox names. This option causes Dovecot to
# ignore the extra '/' instead of treating it as invalid mailbox name.
# tb-lsub-flags:
# Show \Noselect flags for LSUB replies with LAYOUT=fs (e.g. mbox).
# This makes Thunderbird realize they aren't selectable and show them
# greyed out, instead of only later giving "not selectable" popup error.
#
# The list is space-separated.
#imap_client_workarounds =
# Host allowed in URLAUTH URLs sent by client. "*" allows all.
#imap_urlauth_host =
protocol imap {
# Space separated list of plugins to load (default is global mail_plugins).
#mail_plugins = $mail_plugins
# Maximum number of IMAP connections allowed for a user from each IP address.
# NOTE: The username is compared case-sensitively.
#mail_max_userip_connections = 10
mail_max_userip_connections = 40
