Feature: show sender adress

[funktionierbar]

Hi,

another thing that was kind of irritating at the start, is that the original sender of a mail is not routinely added to the relayed mail. If the person sending the mail does not sign his/her name in the mail, the mail gets relayed anonymously and there is no way to figure out who sent it.

changing the headers would be helpful like this:
from: original-sender@example.com
to: listmail@example.com
reply-to: listmail@example.com

thanks a lot!
