I started working on a zimbra install for a small (5 users, but huge mailboxes) server last friday. It's up and running, and postfix accepts email but the MTA in Zimbra does not yet seem to deliver or receive email messages.

Working thru that.

On a seperate note, I am wondering if it is possible to use the LDAP server that comes with Zimbra to act as a LDAP server for Linux authentication via PAM LDAP. Has anyone tried to do use Zimbra for that yet?
