##NAME: IMAP_PROXY_FOREIGN:0
#
# Proxying to non-Courier servers. Re-sends the CAPABILITY command after
# logging in to the remote server. May not work with all IMAP clients.
IMAP_PROXY_FOREIGN=0
##NAME: IMAP_IDLE_TIMEOUT:0
#
# This setting controls how often
# the server polls for changes to the folder, in IDLE mode (in seconds).
IMAP_IDLE_TIMEOUT=60
##NAME: IMAP_CAPABILITY_TLS:0
#
# The following setting will advertise SASL PLAIN authentication after
# STARTTLS is established. If you want to allow SASL PLAIN authentication
# with or without TLS then just comment this out, and add AUTH=PLAIN to
# IMAP_CAPABILITY
IMAP_CAPABILITY_TLS="$IMAP_CAPABILITY AUTH=PLAIN"
##NAME: IMAP_TLS_ORIG:0
#
# For use by webadmin
IMAP_CAPABILITY_TLS_ORIG="$IMAP_CAPABILITY_ORIG AUTH=PLAIN"
##NAME: IMAP_DISABLETHREADSORT:0
#
# Set IMAP_DISABLETHREADSORT to disable the THREAD and SORT commands -
# server side sorting and threading.
#
# Those capabilities will still be advertised, but the server will reject
# them. Set this option if you want to disable all the extra load from
# server-side threading and sorting. Not advertising those capabilities
# will simply result in the clients reading the entire folder, and sorting
# it on the client side. That will still put some load on the server.
# advertising these capabilities, but rejecting the commands, will stop this
# silliness.
#
IMAP_DISABLETHREADSORT=0
##NAME: IMAP_CHECK_ALL_FOLDERS:0
#
# Set IMAP_CHECK_ALL_FOLDERS to 1 if you want the server to check for new
# mail in every folder. Not all IMAP clients use the IMAP's new mail
# indicator, but some do. Normally new mail is checked only in INBOX,
# because it is a comparatively time consuming operation, and it would be
# a complete waste of time unless mail filters are used to deliver
# mail directly to folders.
#
# When IMAP clients are used which support new mail indication, and when
# mail filters are used to sort incoming mail into folders, setting
# IMAP_CHECK_ALL_FOLDERS to 1 will allow IMAP clients to announce new
# mail in folders. Note that this will result in slightly more load on the
# server.
#
IMAP_CHECK_ALL_FOLDERS=0
##NAME: IMAP_OBSOLETE_CLIENT:0
#
# Set IMAP_OBSOLETE_CLIENT if your IMAP client expects \\NoInferiors to mean
# what \\HasNoChildren really means.
IMAP_OBSOLETE_CLIENT=0
##NAME: IMAP_UMASK:0
#
# IMAP_UMASK sets the umask of the server process. The value of IMAP_UMASK is
# simply passed to the "umask" command. The default value is 022.
#
# This feature is mostly useful for shared folders, where the file permissions
# of the messages may be important.
IMAP_UMASK=022
##NAME: IMAP_ULIMITD:0
#
# IMAP_ULIMITD sets the maximum size of the data segment of the server
# process. The value of IMAP_ULIMITD is simply passed to the "ulimit -d"
# command (or ulimit -v). The argument to ulimi sets the upper limit on the
# size of the data segment of the server process, in kilobytes. The default
# value of 65536 sets a very generous limit of 64 megabytes, which should
# be more than plenty for anyone.
#
# This feature is used as an additional safety check that should stop
# any potential denial-of-service attacks that exploit any kind of
# a memory leak to exhaust all the available memory on the server.
# It is theoretically possible that obscenely huge folders will also
# result in the server running out of memory when doing server-side
# sorting (by my calculations you have to have at least 100,000 messages
# in a single folder, for that to happen).
IMAP_ULIMITD=65536
##NAME: IMAP_USELOCKS:0
#
# Setting IMAP_USELOCKS to 1 will use dot-locking to support concurrent
# multiple access to the same folder. This incurs slight additional
# overhead. Concurrent multiple access will still work without this setting,
# however occasionally a minor race condition may result in an IMAP client
# downloading the same message twice, or a keyword update will fail.
#
# IMAP_USELOCKS=1 is strongly recommended when shared folders are used.
IMAP_USELOCKS=1
##NAME: IMAP_SHAREDINDEXFILE:0
#
# The index of all accessible folders. Do not change this setting unless
# you know what you're doing. See README.sharedfolders for additional
# information.
IMAP_SHAREDINDEXFILE=/etc/courier/shared/index
##NAME: IMAP_ENHANCEDIDLE:0
#
# If Courier was compiled with the File Alteration Monitor, setting
# IMAP_ENHANCEDIDLE to 1 enables enhanced IDLE mode, where multiple
# clients may open the same folder concurrently, and receive updates to
# folder contents in realtime. See the imapd(8) man page for additional
# information.
#
# IMPORTANT: IMAP_USELOCKS *MUST* also be set to 1, and IDLE must be included
# in the IMAP_CAPABILITY list.
#
IMAP_ENHANCEDIDLE=0
##NAME: IMAP_TRASHFOLDERNAME:0
#
# The name of the magic trash Folder. For MSOE compatibility,
# you can set IMAP_TRASHFOLDERNAME="Deleted Items".
#
# IMPORTANT: If you change this, you must also change IMAP_EMPTYTRASH
IMAP_TRASHFOLDERNAME=Trash
##NAME: IMAP_EMPTYTRASH:0
#
# The following setting is optional, and causes messages from the given
# folder to be automatically deleted after the given number of days.
# IMAP_EMPTYTRASH is a comma-separated list of folder:days. The default
# setting, below, purges 7 day old messages from the Trash folder.
# Another useful setting would be:
#
# IMAP_EMPTYTRASH=Trash:7,Sent:30
#
# This would also delete messages from the Sent folder (presumably copies
# of sent mail) after 30 days. This is a global setting that is applied to
# every mail account, and is probably useful in a controlled, corporate
# environment.
#
# Important: the purging is controlled by CTIME, not MTIME (the file time
# as shown by ls). It is perfectly ordinary to see stuff in Trash that's
# a year old. That's the file modification time, MTIME, that's displayed.
# This is generally when the message was originally delivered to this
# mailbox. Purging is controlled by a different timestamp, CTIME, which is
# changed when the file is moved to the Trash folder (and at other times too).
#
# You might want to disable this setting in certain situations - it results
# in a stat() of every file in each folder, at login and logout.
#
IMAP_EMPTYTRASH=Trash:7
##NAME: IMAP_MOVE_EXPUNGE_TO_TRASH:0
#
# Set IMAP_MOVE_EXPUNGE_TO_TRASH to move expunged messages to Trash. This
# effectively allows an undo of message deletion by fishing the deleted
# mail from trash. Trash can be manually expunged as usually, and mail
# will get automatically expunged from Trash according to IMAP_EMPTYTRASH.
#
# NOTE: shared folders are still expunged as usual. Shared folders are
# not affected.
#
IMAP_MOVE_EXPUNGE_TO_TRASH=0
##NAME: OUTBOX:0
#
# The next set of options deal with the "Outbox" enhancement.
# Uncomment the following setting to create a special folder, named
# INBOX.Outbox
#
# OUTBOX=.Outbox
##NAME: SENDMAIL:0
#
# If OUTBOX is defined, mail can be sent via the IMAP connection by copying
# a message to the INBOX.Outbox folder. For all practical matters,
# INBOX.Outbox looks and behaves just like any other IMAP folder. If this
# folder doesn't exist it must be created by the IMAP mail client, just
# like any other IMAP folder. The kicker: any message copied or moved to
# this folder is will be E-mailed by the Courier-IMAP server, by running
# the SENDMAIL program. Therefore, messages copied or moved to this
# folder must be well-formed RFC-2822 messages, with the recipient list
# specified in the To:, Cc:, and Bcc: headers. Courier-IMAP relies on
# SENDMAIL to read the recipient list from these headers (and delete the Bcc:
# header) by running the command "$SENDMAIL -oi -t -f $SENDER", with the
# message piped on standard input. $SENDER will be the return address
# of the message, which is set by the authentication module.
#
# DO NOT MODIFY SENDMAIL, below, unless you know what you're doing.
#
SENDMAIL=/usr/sbin/sendmail
##NAME: HEADERFROM:0
#
# For administrative and oversight purposes, the return address, $SENDER
# will also be saved in the X-IMAP-Sender mail header. This header gets
# added to the sent E-mail (but it doesn't get saved in the copy of the
# message that's saved in the folder)
#
#
# WARNING - By enabling OUTBOX above, *every* IMAP mail client will receive
# the magic OUTBOX treatment. Therefore advance LARTing is in order for
# _all_ of your lusers, until every one of them is aware of this. Otherwise if
# OUTBOX is left at its default setting - a folder name that might be used
# accidentally - some people may be in for a rude surprise. You can redefine
# the name of the magic folder by changing OUTBOX, above. You should do that
# and pick a less-obvious name. Perhaps brand it with your organizational
# name ( OUTBOX=.WidgetsAndSonsOutbox )
HEADERFROM=X-IMAP-Sender
##NAME: OUTBOX_MULTIPLE_SEND:0
#
# Remove the following comment to allow a COPY of more than one message to
# the Outbox, at a time.
#
# OUTBOX_MULTIPLE_SEND=1
##NAME: IMAPDSTART:0
#
# IMAPDSTART is not used directly. Rather, this is a convenient flag to
# be read by your system startup script in /etc/rc.d, like this:
#
# . /etc/courier/imapd
#
# case x$IMAPDSTART in
# x[yY]*)
# /usr/lib/courier/imapd.rc start
# ;;
# esac
#
# The default setting is going to be NO, so you'll have to manually flip
# it to yes.
IMAPDSTART=YES
##NAME: MAILDIRPATH:0
#
# MAILDIRPATH - directory name of the maildir directory.
#
MAILDIRPATH=Maildir
