Normally on a Zimbra server you setup a domain (domain.com). If you send a message from your Zimbra server to email@example.com it does not lookup the MX record of domain.com but rather just attempts to do local delivery of the message (this is pretty normal email server operation).
My question is, Is there any way for force an MX lookup on domain.com even if that domain is setup on the Zimbra server. I want to send email from the Zimbra server and have it routed to another server rather than delivered locally.
I realize this is a screwy way to do things but it will solve a problem I am trying to fix.
