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@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.
