[Mailman-Users] Any way to add sender email address to subject line or body of email?

[Dan Watts]

Due to many sites now blocking emails that do not come from the defined
list of sending hosts, I've changed the lists I manage to replace the
"From:" header with the list address using "anonymous_list". This works
great for delivery but many people don't bother to sign their emails and
we end up not knowing who is posting. It would be great if I could put
the sender email address in the subject line or as a first line in the
body of each posting. Is there a way to do either one of these things?
