GTM exchange SMTP..

Quick one, will a GTM device pass through the originator ip address to the relay server by default?

No. The DNS query to GTM will be completely independent to the subsequent data connection by the client over SMTP.

Bit confused, so the only way to get smtp relay load balanced is to set it up on the ltm layer then set Source Address Translation to none and add a route from the relay box back to the ltm? Wanted to try just use the GTM layer?
