phMailer question

[Bamboozle]

Hi everyone, first post here, so hello all.

I am trying to adapt the phMailer form so that it sends email from my email address, my host (dreamhost) block any emails that are sent by web pages from a non-dreamhost email address, so I need to make sure it's coming from my email address or it won't work!

I'm guessing this is the line I need to adapt:

$headers.="X-Sender: ".$_SERVER['REMOTE_ADDR']."\n";

But with php not being my first spoken language I can't get it to work, any help would be greatly appreciated
