I don't really mind that I'm dropping mail from the lists (since I don't seem to be getting any false positives) and I'm not particularly worried about the quality of the filtering on lists - I find the notification messages *much* more annoying than the spam itself. -- "You grabbed my hand and we fell into it, like a daydream - or a fever." -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

I can't find the bit in there that stops you sending the contentless bounce message? Can you point me at it so I can send a patch to include how close to the threshold I am and also patch it so that DDs can disable it? Thanks, Simon. -- [ "No, the radio works.

When we see spam getting through to the lists, we already adjust the spam filters. If you think you can do a better job, the spamassassin rules are all publicly available, and we gladly accept patches.

I'm not convinced that's really true. You obviously have some system that generates the messages based on bounces and that records which message bounced. If many subscribers bounce the same mail that's a good indication that it's spam. Perhaps instead of sending these content-free notes that we're going to be unsubscribed some time, after some undisclosed number of bounces, listmasters could consider these messages as hints with which to adjust the spam filter used. -- --("Do you have a girl coming over?" - Scully)-- Simon ("What's a girl?" - Mulder ) Nomis Htag.pl 0.0.22 signature.asc Description: Digital signature

Wouldn't it be possible to configure the mail server to filter the mail based on the header content? That is, * Is it spam? => Yes => Now do the following: 1. If mail from a mailing list or precedence Bulk or has List-Id in headers, discard it 2. Reject with 5xx - Spam This is kind of what I have setup postfix to do except I filter based on source IP - could be easier to setup in master's case. If mail is from a known mailing list server (eg. debian, sourceforge), it gets accepted and processed in a post queue filter with spam being dropped. If mail is not from a known mailing list server, it goes to default configuration which does pre-queue filtering where spam is rejected with 5xx SMTP level message. I'm sure it would be possible to set it up based on the existence of Priority: Bulk or List-Id: headers. The only side effect is sometimes the number of connections are more than the server can filter, but that is not generally a significant problem. It just means the connection is delayed for a few minutes. - Adam -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

It would be nice if the mail indicated what that threshold is, so that we know whether this is an immediate cause for concern. The FAQ merely says "it depends" (with some details, but not enough to do an accurate check), so perhaps the program that generates the mail is in a better position to say. -- Colin Watson [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

The problem is that the filtering is differential; master.debian.org should be reconfigured to either just accept these messages from lists, or discard them. As listmaster has nothing to do with the mail configuration on master, there's not much listmaster can do about it.

Is master unsuitable to receive mail from lists.debian.org?
Hello. I tried to contact [EMAIL PROTECTED] about this without success, so this time I will Cc: debian-devel, as it would be extremely strange that I'm the only person with this problem. Executive summary: master.debian.org, where I receive debian email, has stronger spam filtering than lists.debian.org, as master seems to use some kind of "content filtering". As a result, some spam messages distributed by lists.debian.org are rejected by master.debian.org. This is insane! Please do agree on a set of filtering rules for master and lists.debian.org which do not make lists.debian.org to send messages to master that master will then reject.
