Email Class - Not able to set Return-Path header

[eluser]roguemonk[/eluser]
I'm a little late to this party.

It actually sucks that this isn't working, but I wonder if it isn't the email server making the changes. What protocols is phpmailer using? I tried sendmail and smtp with no luck. Didn't try mail.

In the interim, a quick solution might be to set the from email to your Return-Path and make reply_to your preferred "human-readable" email (I'm assuming most people will just hit 'reply' on an email). In tests, this seems to work, but I haven't tested across multiple clients.

It doesn't fix the underlying problem, but might allow us to use the email class for simpler projects requiring this.

Thoughts?
