I just setup courier-mta on my new laptop with Debian testing and it
works "out of the box" with PAM. Can you sent the log entries from
the failed delivery ?

This is the complete log output from syslog:

Somehow, getpw() fails while other applications are able to look up the homedir of a given user. All user data is stored in LDAP. But since PAM is used, I guess this should not matter. Still, Imapd is working fine.

Just wanted to add this comment to the 'LDAP' bit:
a search using `ldapsearch -x -h localhost homeDirectory` successfully returns all home directories using anonymous bind, so I'm pretty sure that LDAP can be ruled out as the source for this problem.

P.S.: I have switched to authldap for the moment but it gives me some headache, too, since it makes the server output a "456 Address temporarily unavailable" every now and then. So I'd really like to get authpam back... :P

Using Tomcat but need to do more? Need to support web services, security?
