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!
