I have been evaluating ZCS 5 as a possible replacement for another email server we have been using. The setup we have now is the "to be replaced" server is configured for multiple domains (example.com, domain.net, etc..). Those domains have "post offices" for each domain. There are a few mailboxes that we need in each domain for programmatic access from our applications to POP into and process emails sent there. The rest of the email that does not have a mail box is relayed to our corporate Microsoft Exchange servers.
My question is this:
For each post office/domain we can specify where to relay/smarthost email to. Does ZCS have that ability?
What I can tell is the MTA only lists a single relay address.
Thanks in advance!
