Hi all,
Quick question. We have a situation where we want to forward all unresolved mail to a smart host. We have set this up by setting the domain to an internal relay domain and adding a smart host connector to the send connectors. All good right?
Well, no. Unfortunately it looks as though for some reason, ALL mail coming in to this domain is being routed out through the send connector, even though the recipients DO exist on the internal Exchange server.
I'm not 100% sure why this is happening, but the only thing I can think of is:
2 domains exist:
thisismyfulldomain.com < Primary
timfd.com < Secondary (and the one that is now set as an internal relay domain)
Every user has thisismyfulldomain.com as their PRIMARY SMTP address, and timfd.com is a secondary address. It appears as though ALL mail to timdf.com is being routed through the send connector. Could it be the case that when the internal relay "checking" happens that it only checks against the primary SMTP address and doesn't check all of the users SMTP addresses?
If this is not the case then I have no idea what's going on. Anyone might be able to shed some light?
Cheers,
Rich
