Courier-IMAP

Courier-IMAP is software to provide an imap service, i.e. a daemon.

= Installation =

Install it as described under installing software. Start the imap daemon like this: /etc/init.d/courier-imap start Verify that it is running like this: lvps87-230-12-146:/etc # nmap localhost | grep 143 143/tcp  open  imap Configure the daemon via /etc/courier-imap/imapd. The only change I did was AUTHMODULES="authpwd" This line has the effect that /etc/passwd is used to authenticate the imap users.

= TroubleShooting =

login to server failed
If you get the error message "login to server failed", it is probably because your authentication daemon is not running. So, start it and restart courier /etc/init.d/saslauthd restart /etc/init.d/courier-imap restart
