mail routing problem (help!)

[ctjohnson]

Hi-
We've set up our exchange email server in our domain, in addition to a legacy mail server. Most usres are still on the old server, so we forward mail to the exchange server. This works well, with one problem: when you try to send mail to someone internally who does not have an exchange account, just an account on the old server, exchange returns it saying the account does not exist.

To get around this, I try to send mail from user@exchange.domain.com to user@oldserver.domain.com...in this case, I get a message that mail is returned because of a 'mail loop'

Any ideas?

Maybe a better way to put this would be to say:

If we have two mail servers serving the same domain, an exchange and a legacy server, is there a way to tell the exchange server to not return messages, but forward them to the other mail server if there isn't a mailbox for the user the mail is being sent to in exchange?

help!

Under the smtp virtual server\messages you can forward all unresolved recipients to host. Place old server here. Also there is a setting that says something like this is the only mail server for this domain yours shouldn't be checked since there is another one out there. Forgot where it is and too tired to look right now. If you are still having troule tomorrow i will check for you
