Courier IMAP
see man imapd for using file alteration monitor (package fam).
configuration files all live in /etc/courier
install packages
> apt-get install courier-base courier-authdaemon fam \
courier-ldap courier-imap courier-ssl courier-imap-ssl \
courier-pop courier-pop-ssl courier-doc
It is your choice if you want directories or files for the courier configuration. These notes assume files.
startup script
here is a handy startup script to start and stop all courier processes.
/etc/init.d/courier:
#!/bin/sh
case "$1" in
start)
/etc/init.d/courier-authdaemon start
/etc/init.d/courier-imap start
/etc/init.d/courier-imap-ssl start
/etc/init.d/courier-pop start
/etc/init.d/courier-pop-ssl start
;;
stop)
/etc/init.d/courier-authdaemon stop
/etc/init.d/courier-imap stop
/etc/init.d/courier-imap-ssl stop
/etc/init.d/courier-pop stop
/etc/init.d/courier-pop-ssl stop
;;
restart | reload | force-reload)
$0 stop
sleep 1
$0 start
;;
*)
echo "Usage: $0 {start|stop|reload}" >&2
exit 1
;;
esac
exit 0
logging
NOTE: instead of this hack, just use syslog-ng instead. It will let you send all
the courier log entries to a courier file, plus can slice and dice (and remove IPs!).
in tcpd/logger.c, change LOG_MAIL to LOG_LOCAL3 this way, we can log to a different log file, which is really nice to be able to do. copy the tcpd/logger executable to /usr/sbin/courierlogger (or where it is specified in /etc/init.d/courier-*).
edit /etc/syslog.conf:
local3.* -/var/log/courier.log
testing
Once you have courier all configured, you can test authentication and the user backend by using courierauthtest:
# courierauthtest <user> [password]
for example:
# courierauthtest redcursor xxxxx
Authenticated: module authdaemon
Home directory: /var/maildir/r/redcursor
UID/GID: 8/8
Maildir: /var/maildir/r/redcursor
AUTHADDR=redcursor
AUTHFULLNAME=Red Cursor Collective
OPTIONS=<none>
if it is not working, you will get
Authentication FAILED!
