Trouble sending emails
I am getting myself well acquainted with ZCS. Which I have to say, I REALLY like. Except for the whole can't send email issues. I can receive them from the outside world, but nothing makes it past the MTA for outgoing mail.
Using the Web Mail Client, I get the following error message the FIRST time I hit send:
try again: unable to connect to the MTA.
If I hit send a SECOND time, I get this message:
system failure: Unable to get SMTP session for...
The zimbra.log shows no errors/failures/issues that I can recognize. The nmap shows smtp assigned to port 25.
Dig shows this:
The version of ZCS: Release 6.0.6_GA_2330.UBUNTU8_64 UBUNTU8_64 FOSS edition.

I've attempted to change the MTA global settings to use various hosts as defined on the system. The original value I had was set to "rt1". Here's the contents of my /etc/hosts file:
Any thoughts? It feels like I'm doing something terminally stupid.
127.0.0.1 localhost localhost.localdomain
18.104.22.168 rt1.rocktechonline.com rt1
Thanks for the help!
According to the dig repsonse you have no valid MX record, you need an A & MX record pointing to the Zimbra server. If you're behind a NAT router you'll need a Split DNS set-up.
