Assunto: [Exim] Duplicate sends for a mailing list
I found reference to a problem like this in the list archive, but no
resolution. This list has about 850 members and is managed by
majordomo. I'm running exim 3.21 on Solaris 2.6. The problem is that
apparently arbitrary members of the list are receiving multiple copies
of the messages. Not all messages, not all members. Below are log
excerpts demonstrating the occurence.

First majordomo sends one message to the list.

2001-01-26 18:47:45 14MIan-0003E2-00 <= owner-marbio@???
U=majordomo P=local S=5674
id=5.0.0.25.0.20010126153534.02e90830@???

Sometime later, six deliveries are made to the same address (mine) --
note the message ID is the same for all. It seems that later deliveries
get more copies. The initial several deliveries only got one in this
case. Those who get one vs more seem quite arbitrary, but may be
related to passage of time (interveneing queue runs? "-bd -q15m" ).
The occurence of this kind of delivery may also be related to message
size, if that could be a clue. It's quite nasty when multiple copies of
a large post put people over-quota. Thanks for any help.
