I may have been misleading - I'm not sure that sendmail has anything to
do with it really. The mail gets to sendmail on the list server, there
are two entries there, one saying from xxx at N and one showing it being
piped to mailman/mail/wrapper post list
A few seconds later this shows up in the mailman smtp log
Jan 29 10:13:01 2003 (4859) smtp for 112 recips, completed in 0.315 seconds
After that point I have no knowledge as mailman is using an SMTPHOST (at
our internet provider) which I believe is exim but I don't know the version.
Once the mail comes back to our main mail server (Groupwise), the logs
show one incoming message from the list admin to each local member of
the list, which I guess is what you would expect.

I'm on the list and I get 11 copies (not including the one CCd directly
to me). The strange thing is that messages sent directly from people at
"N" work fine. Messages sent to the list from anyone else work fine.
And after a bit of digging it seems that not all the recipients do get
11 copies, although I haven't been able to find a correlation between
those that do and those that don't - though it does seem to be a per
site rather than per person basis.
Hope that makes sense,
