Hi,
I have a customer that uses Mailman on their VPS (Virtual Private
Server) running the Plesk Control Panel. After a recent upgrade of
Plesk, they can no longer send a single email to multiple lists.
Supposedly, this worked prior to the upgrade.
For example, if they send a message to list1 at domain.com and 'CC'
list2 at domain.com, only list1 recipients receive the email. I was able
to reproduce this behavior on a test VPS we have available here at our
office. I'm able to send to each test list individually but when I send
to one list and 'CC' the other, I only receive emails from the first list.
The mail server logs show the initial email going out to both list
addresses so I'm not sure why one is being "dropped" after reaching
mailman. I experimented with the Mailman Privacy Options | Recipient
Filters and set "Must posts have list named in destination (to, cc)
field (or be among the acceptable alias names, specified below)? " to No
for both of my test lists, but this didn't help resolve the issue.

I'd really appreciate any suggestions!
