For Mailman 2.2, I am considering changing the Sender: header from the
LIST-bounces address to the LIST posting address. As discussed in the
FAQ at <http://wiki.list.org/x/RoA9>, I think this is in the spirit of

However, I am nervous about this. There are potential problems with
non-compliant/brain-dead software that might inappropriately direct
bounces or out of office/vacation messages to the Sender: where they
might end up on the list.

I think that bounces aren't of great concern as I think there are few
MTAs that return bounces to other than the envelope sender, and even
if an MTA returns a bounce to Sender: it likely won't be From: a list

I'm more concerned about out of office/vacation messages.

I would like to hear from anyone who as actually made this change
(putting the list posting address in Sender:). If you have done this,
do you notice an increase in these kinds of messages reaching the list.
