OK, so for this list the email address would be locked to sender:
	mimedefang-bounces at lists.roaringpenguin.com

But for the SpamAssassin list (for example), the senders are all different:
	All the below are @spamassassin.apache.org:
	users-return-33376-Matthew.van.Eerde=hbinc.com
	users-return-33377-Matthew.van.Eerde=hbinc.com
	users-return-33378-Matthew.van.Eerde=hbinc.com
	...

So the best I could do is lock to @spamassassin.apache.org
