[SOLVED] Weird mail loop between domains on zimbra server

[MoreDakka]

Hi,

Here is the setup:

domain.com
2nddomain.com

both on the same Zimbra server. We have a Barracuda Spam filter as our Relay server for both incoming and outgoing email. I've got both the "Relay MTA for external delivery" and "Inbound SMTP host name" set to the IP of the Barracuda. The Barracuda forwards email either direction no problem.

I've got a user that wants aliases from domain2.com to forward to his domain1.com email address.

admin@2nddomain.com -> joe@domain.com
user@2nddomain.com -> joe@domain.com

When an email is sent to either 2nddomain.com addresses it goes through a mail loop then gets a top many hops bounce sent back to the sender. I can send locally to joe@domain.com no problem. I don't know why, I would think Zimbra would see that 2nddomain.com is a local domain and not forward it out to the external relay?

Thanks.

Any takers, no ideas?

So even after creating the user "admin@2nddomain.com" I still cannot send to this domain. It just keeps being sent back to the barracuda then right back to the zimbra server which sends it back to the barracuda...etc...etc...

Wow....so dumb...looks at me and how awesome I can spell. Horrible. This domain has two t's in it and I created it with only 1. No wonder it wasn't working. sigh.
