While the SMTP relay in ISA may be able to do that, by RFCs, you can not have 1 Public IP address linked to more than 1 mail server. You can have multiple IP address for 1 server, but not multiple servers for 1 IP address.

Well, you could bind another ip to the external interface then publish it but if you cant do that use the smtp relay on the isa and let it collect mail for all domains and forward to whichever internal server (mail relay) it belongs too.

Web publishing rule will publish the OWA website on the internal server as well. Follow the guide Tom gave you, you cant miss. Greg _____ From: Qusai A.
