Hi,
Actually I had figured it out shortly after my post. Came back to post a reply, but saw your friendly reply :)

I want to remove/modify the x-mailer because I do not want the world to know the server login info.

Is the following the proper way to modify the x-mailer?

$Mail::Sender::NO_X_MAILER = 1;
*Mail::Sender::SITE_HEADERS = \"X-Mailer: My Mailer";


Thanks
