Hi,
I am new to the list but old to the LISTSERV :-)
Lately I have been banging my head against the following problem. I would
very much appreciate any ideas, no matter how wild they might seem.
What happens: I have mostly local subscribers, but some are from outside
domains like gmail, hotmail and yahoo. One of the outside domains is our
university central mail system (our department is running its own mail
system). Subscribers, whose addresses are in the university central mail
system intermittently receive list posts duplicated. I traced the problem
in the logs and here is an example of what happens:
1.
At 17:17:28 <poster> sent the mail to [CHEMMAIL] list.
2.
at 17:20:34 LISTSERV received the approval confirmation from <poster> for
[CHEMMAIL] list.
At 17:30:34 (standard 10 minutes delay) the LISTSERV created a list of all
recipients, put them into 8 outbound files, confirmed the mailing to
<poster> and closed the operation. All addresses were on
the list only once.
3.
From 17:30:34 to 17:30:35 LISTSERV passed those outbound files to sendmail
via 127.0.0.1:

At 17:31:13 the message was accepted for delivery by smtp2.ns.utoronto.ca

At 17:41:38 LISTSERV sent again one block of addresses with the same
message ID but different sendmail ID.

6.
At 17:42:05 the message was resent to all UTORmail recipients in 4 blocks
of addressees identical to the previous blocks of addressees.

It seems clear that the bifurcation occurs at the LISTSERV -> sendmail
level. However, there is no trace of that in the LISTSERV log. The last
entry in that log is 17:30:34 (send job finished) followed by an unrelated
entry at 18:38:53.
Thanks
Frank
