Our mail goes out by smtp and all settings are correct, the mail just seems to be turned back from the Exchange server immediatly after you send it Server running exchange 5.5 sp3

Verifiy that the user has a SMTP EMail address setup . This can be done by entering the user mailbox and selecting the Email address TAB.

Also If you have a Firewall I know that some of them require that you create a mail mapping for each user that will use SMTP Email address.

Hopes this helps.

I think SMTP error is for a bad return address. Check the return address for typos, and that it has a proper domain name in it.

If the IMS is set. Make sure you don't have any delivery restrictions on the IMS. If that is all fine and dandy, then check and make sure that the routing tab in IMS properties is set to reroute incoming SMTP.

You are relying mail to another smpt server like a viruswall or you have a restrictions (outgoing) on your exchange server.
The main message is "sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1) "
