I am in over my head on this one ... I would like to host a mail server on my domain and also be able to retrieve email from my external POP account. I have configured the MTA to "Standard", "Permanent Connection", Outgoing Mail server has been left blank, Incoming Mail is set to accept remote SMTP connections, firewall port is open, forward root to user@domain and delivery mode is Directly.
Evolution has both accounts defined.
Spam filters are disabled.

The POP account is able to send and receive just fine but the user@domain while it goes through the motions never receives anything nor sends anything. I have played with the various receiving server types and for now have Stand UNIX mbox spool file selected - not for any other reason than it doesn't generate errors when I do a Get mail ....

Any input appreciated.
