Yet another Sendmail thread... SMARTHOST not working
Ok, here's what I got...
RH 7.3, located on DMZ at work. I need to have mail go to users at my company (mydomain.com). 172.20.3.1 is the NAT'd ip of our Iron Mail Applicance here, which I can ping and telnet to.
When i use /usr/sbin/sendmail -v localuser
I am told that relay=[172.20.3.1], but when I send email to firstname.lastname@example.org I get, relay=root@localhost.
I don't get this.... why is it using the smart host for local accounts, and not for external addresses?
I must be missing something, but in the last 2 days of googling and reading and verifying with my IT staff that our mail relay is set to accept mail from my linux server, I don't have an answer.
If anyone has any idea, hints, clues they could throw my way, I'd really appreciate it.
Oh, and the error I get from sendmail is that name resolution timed out.
This shouldn't matter if I'm using a smarthost right.... it should just deliver the mail to the relay and not care about where it's going???
