Hi Rob, That would be a nice feature. But no, you can't do that.

I'm guessing this is a fairly simple question. Hope so, anyway. We have three servers that do SMTP outbound. Is there a way to have each one send SMTP traffic from a different IP address on our one ISA server? I'd like to isolate them to different IP addresses so when one gets blacklisted (as happened over the weekend) they don't all get blacklisted.
