I am using courier imap. which logs should i check?
By default courier logs errors in /var/log/maillog (on RH/CentOS)
Courier has a separate authentication mechanism - courier-authlib. I am not aware of ISPconfig, but normally - you will find the config file as /etc/authlib/authdaemonrc
set debug level to 2 (which is the highest level, if my memory does not fail me)
Then first check through telnet =>
On the server (if courier is bound to the localhost IP) =>
telnet localhost 143
. login <username> <password>
Do not miss the dot space (. ) before login above See what response you get
keep a tailf /var/log/maillog running in another terminal and note the error.
btw, what is the auth-backend - mysql or ldap ? you may check that and also pls check whether the maildir (I am assuming maildir format is used ) for the user in question exists...
