[Mailman-Users] ghost subscriptions

[Ron Echeverri]

I have a mailing list where some people are getting two copies of a
message, and others are getting a copy of the message even after
they've unsubscribed.

Now, i'm very certain this is NOT mailman's fault.  However, i would
like to know if there's some header that can be turned on in mailman
that indicates the intended recipient of each message (similar to
postfix's "Delivered-to:").  Yes, i realize i could install postfix,
but this happens to be occurring on an Exchange server, so...

thanks
