It would be nice if you could specify an IP for outbound traffic originating from a published server.

For example, you have ISA server 196.1.1.254 and Mail Server 196.1.1.100 published SMTP Server (25). Part of a mail server's job is to send Delivery status notifications. So the server originates traffic to another mail server on port 25, the problem is that the other mail server sees the traffic with the ISA server's IP primary IP address .254 and not the Mail server's IP .100.

The most common advice for this is to change the primary IP of the ISA server. That only works if you have 1 mail server behind ISA. In fact all traffic originating behind the ISA server gets the IP of .254.

Would be nice of you could somehow specify that the outbound traffic from the mail server goes out with its correct IP of .100
