I have a CAS published behind an ISA 2006 server. I a need to allow certain public Ip address to relay to the outside world. I have added the ip address(s) to any allow list on the cas server I can think of. If I allow the ISA server to relay the I become an open relay..... Any thoughts?

This all depends on your own personal config. For example: We have an SMTP on port 25 that requires authentication. We then created another SMTP connector on an alternate port that allows relaying, say port 2525. On the firewall, for any inbound coming from IP's we want to allow relaying, we use PAT and change it to port 2525 and send it to that SMTP connector. Thats just how we did it, depending on your knowledge and equipment your results may vary. "Romualdt" wrote: > I have a CAS published behind an ISA 2006 server.
