Ok I follow you. So I should load IIS and use SMTP on the ISA server to relay for the Mercury? I am going to end up having another mail domain at the site. It will be Ex2K. I won't have the same problem with it I assume?

You can use IIS SMTP to relay the messages on behalf of Mercury. ISA itself can do it well. Publishing your internal Mercury with ISA just takes care of incoming SMTP messages. -----Original Message----- From: Toby Yeager [mailto:tobyyeager@xxxxxxxxxxxxxxx] Sent: terça-feira, 14 de agosto de 2001 02:05 To: [ISAserver.org Discussion List] Subject: [isalist] SMTP Relay Problem http://www.ISAserver.org Hello all, I am having a strange SMTP problem. I have ISA running in integrated mode and my servers are all SNAT clients. What is happening is this. I have a Netware 4.11 server on the internal network that is running Mercury for email services. When users try to send email outside of the state domain (k12.ar.us) it gives a relaying error. I have been informed that the mail is coming from the wrong IP. I have several IPs bound to the external NIC of ISA for email and web and such. I used mail publishing to set up the mail server on ISA and pointed it at the IP for that mail domain. Why does it use the default ISA IP instead?
