I have all those things. I researched a bit more and found this.
When I first set up this server, I could not send mail out. I learned I had to set the mailhost in the submit.cf file, and that worked. Then what I found was that local email (ie)
user@host.domain.com or even to root, was not longer being delivered.
I need to have all root mail delivered locally and mail addresses to
user@host.domain.com delivered locally, but all other mail sent to the relay server. I also need all addresses that have no domain appended (ie) mailuser, sent to the relay as
mailuser@domain.com (not
mailuser@host.domain.com). Right now they are trying to be delivered locally, which I understand is the submit.cf behavior.
I do not want this server listening on port 25.
Any ideas?
Thanks
