[Mailman-Users] Variable for sender's email?

[Andy Peed]

Apologies if I have missed this in the archives...

I have a mailing list in which replies are by default directed back to the
list. I place a header on each message which indicates this and asks that
the To: line be changed if the reply is to be sent only to the sender.

I have been asked if the sender's email address could be placed into that
header specifically. Is there a variable I can use to do that?

Thanks...
