[Mailman-Users] duplicate messages sent

[Brian Ryner]

I've never had this happen before but it happened this morning.  A
message was sent to the mailing list, and many people on the list got
the message twice (but not everyone).  I'm suspecting something gone
wrong in the dividing up of the mail into batches.  The system is
running Slackware 3.2, Mailman 1.0rc1, Python 1.51. Has anyone ever seen
anything like this?

I have a complete log of the mailing.... I'm not going to post it
because of the number of email addresses involved, but if there's
anything I should look for, please let me know.  I noticed this:

Jun  2 10:33:34 monm sendmail[15959]: KAA15959:
from=<list-admin at host.com>, size=3445, class=-60, pri=3141445,
nrcpts=101, msgid=<199906021510.KAA15936 at host.com>, proto=ESMTP,
relay=bin at localhost [127.0.0.1]
Jun  2 10:33:34 monm sendmail[15974]: KAA15974:
from=<list-admin at host.com>, size=3445, class=-60, pri=3141445,
nrcpts=101, msgid=<199906021510.KAA15936 at host.com>, proto=ESMTP,
relay=mailman at localhost [127.0.0.1]
Jun  2 10:36:13 host sendmail[15993]: KAA15959:
to=<user1 at domain1>,<user2 at domain1>, ....
....
Jun  2 10:41:24 host sendmail[15994]: KAA15974:
to=<user1 at domain1>,<user2 at domain1>, ....

This is just an example, there were more smtp id's.  I noticed that the
first line has relay=bin at localhost; the second has mailman at localhost...
is that anything to worry about? I'm not an expert on sendmail, so any
advice is appreciated.

Thanks.
