Hmmm. I had one as recently as 5/15 and Return-Path was not touched nor
some of the other places the address appears. It is frustrating that AOL
wants to stop the unwanted e-mail but tries to make it difficult to figure
out who is complaining.

I think so. With personalization on, Mailman is generating a separate
e-mail for each user which passes through Postfix as separate messages
with a unique ID in Postfix. Without personalization, Mailman could pass
as few as one message to the MTA and let the MTA split it into all the
destinations. With personalization, the message for each user comes to the
MTA as a separate message. One of the tradeoffs of personalization is the
increased workload for Mailman and the MTA.
