Your outgoing MTA (Thet.Net-Mailscanner?) is creating this header based
on the envelope recipients of the message.

You may or may not be able to fix this in the MTA.

I think you can avoid this issue by making mailman send a separate
message to each recipient. You can do this in one of the following

1) In mm_cfg.py set


   This is not recommended because it has all the performance
implications of 2) and none of the advantages.

2) In mm_cfg.py set


3) In mm_cfg.py set


   and then on the list admin Non-digest options page set personalize
to Yes. This will only affect individual messages, not digests.

This may be because you have specified a msg_header in non-digest
options. See
which applies to the msg_header as well as the msg_footer. If you
don't think you have a msg_header, make sure the text box is empty,
not just blank.
