[Dovecot] Can't send/receive mail from other domain

[Jeremy Gillick]

I've followed the instructions (
http://wiki.dovecot.org/DovecotLDAPostfixAdminMySQL) to setup Dovecot with
MySql and Postfix but cannot receive from (or send mail to) other domains.

FYI: email messages are supposed to be stored under
/var/mail/mozmonkey.com/<user>/

Directory Permissions: drwxr-xr-x   5 vmail  mail    4096 May 10 12:57
