[Mailman-Users] Easing the unsubscription

[David Ocaña]

Hi,

I'd like to know if there is a way to include on each post the member's 
address to make the unsubscription easier. I receive too many 
unsubscription mails from addresses that are not members, just because 
the member of the list is an alias of these non-members, then I have to 
contact those people for asking if they want to unsubscribe the alias or 
their single address (will be their admin's work of course), and finally 
find the alias in the memberlist which fortunately will have the same 
domain as the people who are trying to unsubscribe.

Is it possible to attach a message like "This mail was sent to 
xxx at domain.xxx. If you want to unsubscribe, please email us to 
xxx-leave at foo.org and from xxx at domain.xxx".

Thanks a lot.

P.S: Sorry for mistakes  ¬_¬'
