Hi,
Thanks for the great replies and help.
I found a perl script "findsender.pl" with google and it seems to be
useful. I seem to have missing mail list members from my maillog,
and one python error from mailman.
Here is what I did to verify non-mailing...
list_members maillist > /tmp/listnames
for person in `cat /tmp/listnames`; do ./findsender.pl $person maillog |
grep 'Found 0'; done
{returns 28 email addresses}
I didn't trust that findsender.pl actually parses postfix logs 100% so I
verified
with plain grep for any mention of the user addresses in /var/log/maillog or
/var/log/mailman/* I found one reference of the 28 which findsender.plmissed.
This list has 1890 members, and 27 are not showing up at all in postfix
logs.
Unless postfix has a bug where some emails are not being logged, there seems
to be a problem with mailman. I'm not looking for delivery - just any
reference
to the expected attempts to deliver.
I do however see an error in /var/log/mailman which matches the time of
this mass mailing:

There are no errors like it in our previous months of using mailman
on other smaller departmental mailing lists. The mailman smtp log does not
show
the entry for the 1800 something messages which were delivered OK.
My hunch, is that there is some bad data in our mailing list subscription
which wasn't caught anywhere and has created this issue. We are given
data from the Alumni Affairs department to inject into the mailing list.
It may contain odd things. I've seen a '#' and single quote appear in
the mail subscriptions.
