[SOLVED] Unable to connect to the MTA Error

[DEpple]

I recently switched my host for my website, but my email is hosted locally on my server. So I don't think that should be a cause for issue. However, our office is now getting the error: Unable to connect to the MTA. When trying to send emails, and we can not receive emails! Please help!

I was directed by another post to check in /var/log/zimbra.log to see why Postfix is not starting.. Please see the result below. The other post did not answer my question so I am desperately asking for help here!

How about starting with the information that was asked for in that thread? Go to the Split DNS article and post the output of all the commands in the 'Verify...' section of that article.
