[Mailman-Users] Personalized Footer

[Larry Hansford]

I have added personalization to the lists, and have added a line in the 
footer that shows:

This message was sent to: member at domain.com

which the list members like, but they would like me to add a line that reads:

This message was sent by: sender at domain.com


Can someone tell me what variable I would use to insert the sender's 
name/address in that line?  This is Mailman 2.1.1.

Thanks!

Larry
