[Mailman-Users] Repeat messages - FollowUp-Summary

[Joseph McCall]

All the permissions look good and the headers don't indicate looping
membership. Some good ideas and certainly appreciated.

The final clue to the puzzle (I think) is that the last two times this has
occurred (previously with Mailman 2.0.5):

	a) the recipients had left the company we were mailing to
	b) they had set up forwarding and
	c) they had set up auto-reply ("I no longer am with...")
	d) (interesting) the receiving mail systems were both running Novell
GroupWise

I'm taking the low-road and blaming the receiving end not returning proper
notification of delivery (though my logs show that they deliveries were
successful).

Anywho, thanks for the replies!

Joe

Looks like the lock files are not working... is the "sticky" bit set
properly on the directory structure?

It looks like qrunner is kicking off every minute (as it is set to do...)
and that it is processing the message in the queue as though no other
qrunner process is running.  The only reason I can think of for it to do
that, would be the lock file not working.  Ordinarily qrunner would see the
lock file on the list and then ignore those messages.

Ahhhh... Here is a long shot - Look at the message headers and see if the
messages are looping.  Could your list be a member of your list?  That would
have the same effect.  Also, someone on the list forwarding their mail to
the list would cause similar damage - those tricky end users!
