Re: debian-user list info and guidelines: spam

There is a comprehensive FAQ on the Debian Wiki which is in need of updating.

Your post provides a hook to ask about a question that arises sporadically: Probably less than one a month I receive from Debian Listmaster Team <listmaster@lists.debian.org> a message "lists.debian.org has received bounces from you". Invariably it reads:
In the last seven days we've seen bounces for the following list:
* debian-user
	1 bounce out of <nn> mails in one day (<x>%, kick-score is 80%)

First: How common is this occurrence for others?

Even when it happens, it will obviously never rise to the kick-score, so it's functionally forgettable. But the post itself is educational, particularly with the background info links, which explain the origin of the problem in spam control, and why bouncing list mail is not nice, and what can and should be done about spam. I'm sympathetic to the problem, but don't run my own mail server [I suspect many on this list do so, and thus are closer to spam issues], and can never get my ISP to care about this.

One aspect on which the FAQ is silent is exactly /how/ the debian lists are filtered for spam. That would probably be too much specificity for a FAQ, but I wonder about it because of a problem I'm having with another list [SOGo], in the opposite direction:
	I cannot currently post to the SOGo list because their spam filter (UCEPROTECT) claims that my ISP currently hosts 6 spammers. In response, they block all mail from that ISP (called UCEPROTECT Level2 protection). Again, getting my ISP to care about this is an ongoing challenge.

Is there an intelligent way to manage when spam control efforts break the system they want to protect? Do the debian lists attempt to control spam by blocking specific users, domains or ISPs?

Kind regards,
