Hi all, Togheter with Effeietsanders I am administering the wikilovesmonuments-l mailing list[0]. This list is receiveing huge amounts of spam messages (quick stat: we are talking about 20 messages per hour). We have tried to implement some spam filter rules following this[1] (a page which I have edited myself) but basically we were unable to get any effect of sorts. Here's the two spam filtering rules I have created: * Rule 1: X-Spam-Score: [+]{2,99} * Rule 2: X-Spam-Score: [*]{2,99} I have added both rules with "+" and "*" to be sure, and I have specified the numbers (more or equal than 2 and less or equal than 99) because in my first try the rule with just {2,} (i.e. "more or equal than 2") was not working. The fact is that the solution didn't work out in the end (we were still holding in our moderation queue lots and lots of messages with an high spam score) and so we are changing the default policy for the list about non-member messages from "Hold" to "Reject" (see [2]) This was quite frustrating, but we were unable to fix the problem is some other way. I am sharing this to make sure I wasn't making some sort of stupid mistake in the rules. This other bug report is related[3]. Thank you.

I have no experience with the spam level and Mailman, so I let someone else answer on this point. For the Reject vs Discard mentionned in your original wikitech email, following [1], Reject rejects the message and warn the sender his/her message was rejected, and Discard rejects the message without any warning send to the sender. The latter is better for spam issues (because of the [[backscatter]] problem, i.e. someone whose address was spoofed by a spammer will get warnings when his/her address is rejected on some mailing lists, even if s/he is not the original sender to the mailing list), but it can be an issue for legitimate users (do not know their message was rejected). At the least, you can add some warning on the info page to say only members can send emails. [1] http://staff.imsa.edu/~ckolar/mailman/mailman-administration-v2.html (search "discard")
It's not clear to me if there is a request in this report for some technical change to fix or work around some well-defined (and described) problem. And how this is different from what's requested in bug 56525. Could you please clarify?
Please answer comment 2.
Poke for the above. It should technically work with a discard.
Unfortunately closing this report as no further information has been provided. Cristian: Please feel free to reopen this report if you can provide the information asked for and if this still happens. Thanks!
