[Mailman-Users] Constant moderation required when user sends to list + CCs

[Steve Campbell]

I've got a list set up for a group of people. One of the users often 
sends an email to the list and adds carbon copy recipients of 
non-members along with the email. The list is on one mail server and the 
CCed recipients go to another mail server. I see in the maillogs of the 
SMTP server she uses that the email is in fact split properly in that 
the email to the list is sent separately to the list server and the CCed 
recipients are sent to the proper server for delivery. These messages 
always require moderation due to the fact that the list server indicates 
there are too many recipients. It's as though the list is using the 
headers with all of the recipients for delivery instead of what it 
actually receives to process.

This is an older version 2.1.5 of mailman. Is there anything I can do to 
remedy this?
