#  This will break the default imapd.rc script, which parses this file.
#
##NAME: ADDRESS:0
#
#  Address to listen on, can be set to a single IP address.
#
# ADDRESS=127.0.0.1

ADDRESS=0

##NAME: PORT:0
#
#  You better have a good reason for changing the port

PORT=143

##NAME: MAXDAEMONS:0
#
#  Maximum number of IMAP servers started
#

MAXDAEMONS=40

##NAME: MAXPERIP:0
#
#  Maximum number of connections to accept from the same IP address

MAXPERIP=4

##NAME: PIDFILE:0
#
#  File where couriertcpd will save its process ID
#

PIDFILE=/var/run/imapd.pid

##NAME: TCPDOPTS:0
#
# Miscellaneous couriertcpd options that shouldn't be changed.
#

TCPDOPTS="-nodnslookup -noidentlookup"

##NAME: AUTHMODULES:0
#
# Authentication modules.  Here's the default list:
#
#    authdaemon
#
# The default is set during the initial configuration.
#

AUTHMODULES="authdaemon"

##NAME: IMAP_CAPABILITY:0
#
# If this version of Courier-IMAP includes support for CRAM-MD5
# authentication (the authcram authentication modules gets compiled and
# installed), you change IMAP_CAPABILITY below to read as follows:
#
# IMAP_CAPABILITY="IMAP4rev1 CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT AUTH=CRAM-MD5"
#
# Otherwise, leave it set to the default value.  The IDLE keyword can also
# be added, in experimental mode.

IMAP_CAPABILITY="IMAP4rev1 CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT"

##NAME: IMAP_IDLE_TIMEOUT:0
#
# If you want to try out the IDLE extension, 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_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 an IMAP's server new mail
# indicator, but some do, and 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 new
# 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_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.  The argument to ulimit -d 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
#
# Set IMAP_USELOCKS to 1 if you experience weird problems when using IMAP
# clients that open multiple connections to the server.  I would hope that
# most IMAP clients are sane enough not to issue commands to multiple IMAP
# channels which conflict with each other.
#

IMAP_USELOCKS=0

##NAME: IMAP_EMPTYTRASH:0
#
# Purge messages from the Trash folder after this number of days.  This is
# mainly for the Netscape Communicator client, which automatically moves
# deleted messages into Trash.  Remove this variable complete to disable
# Trash purging.
#

IMAP_EMPTYTRASH=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: 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:
#
#  . /usr/local/libexec/imapd.config
#
#  case x$IMAPDSTART in
#  x[yY]*)
#        /usr/local/libexec/imapd.rc start
#        ;;
#  esac
#
# The default setting is going to be NO, so you'll have to manually flip
# it to yes.

IMAPDSTART=NO
