SMTP question

I think i might have asked this before, but not sure, as i switched laptops and have not loaded previous emails yet....

I wanted to know if its possible to have smtp IP info forwarded to my postfix MTA... because right now all incoming email looks like it comes from the same IP address which is of course my fabulous HAproxy box, works works so well!
:)
Is there a way to do this?

Thanks to all, and have a great day..
