[Mailman-Users] Looping Moderator Approval Requests / Mailman&Exim

I am having trouble with held posts for the lists I run at Jennic.

We've recently set up Mailman to run in conjunction with Exim and it's 
working very well (withlist -r is invaluable though), but we're having 
trouble with the moderation because it is ending up in a loop (that 
thankfully stops itself after about 30 iterations) but is nonetheless 
proving to be a big pain.

When a post is received that is held for moderation, an e-mail is sent 
to list-owner, but when that is sent back into mailman for forwarding, 
mailman treats the message as if it was going onto the list and holds it 
(because of the included message that was originally help). This then 
generates another moderation e-mail which is sent to list-owner which is 
then held and so on.

I'm not sure if there is a fundamental failure in my understanding of 
the system of if there's something I've not thought about, but I cannot 
get it to work properly.

I've seen a lot of documentation suggesting that every list should have 
10 aliases in the Exim aliases file for piping into mailman, and -owner 
is included in these, however I think I am right in saying that that 
doesn't apply in this situation because I have configured the Exim 
transport/router as directed to pipe all mail into mailman that hasn't 
been caught by aliases instead.

Can anyone shed any light on this for me?

P.S. The main issue here is that we run SpamAssassin on the mailserver 
and it adds an X-Spam_Bar header which we then check for in the list 
Spam Filters. Before, every single spam e-mail was generating 30 
moderator requests.. now we have told the lists to discard anything with 
an X-BeenThere: ListName at company, but it doesn't just stop the loop, it 
prevents all moderator requests reaching the list owner because in the 
end it seems the moderator requests are trying to head for the lists not 
the list owners. It's all very confuzzling.
