Relay to personal mail server proxy original sender host

[dragospanoiu]

Hello, I've been using Purelymail for a while and I tried to link one of my domains to the mail server I have at home.
So for domain example.org I've selected the Relay option in the Domain config, I confirm everythings works fine, emails are relayed to my home mail server.

I have a suggestion here: the destination mail server will always see the Purelymail SMTP IP as sender, not the original one. I tried to see if works like a HAProxy server, but unsuccessful. So the suggestion would be to find a way to be compatible with HAProxy headers like many of known SMTP servers (Postfix) know how to read the original sending IP from this.
