Hello all. For subscribe messages and such, mailman uses the "Sender:" rather than "From:" this is bad. Netscape and many other mailers don't let you set the "Sender:" and mine is _always_ wrong.
My user name is "clark" on my linux box at home, I'm using "mail.mindspring.com" for my SMTP server. Somehow... god know how, I get "Sender: email@example.com" and there is _no_ way I can change that (that I know of).
Now. I'm _not_ firstname.lastname@example.org , yet when I subscribe and stuff, it sends errors to this poor bloke.
Thus, I respectfully request that Mailman use "From:" if it is there.
P.S. I you don't believe me, check the headers for this message.
