Well I'm in still in the dark as to how to resolve this problem with spam from mailing lists. The flood of spam has stopped, but one spam message got through the Debian filters today, so I am likely to be able to continue trying to resolve the problem, with the odd spam getting through the Debian filters from time to time. I have a separate mailbox for the Debian-user list, and when the spam flood was in full flow everything turned up in this mailbox, ham, and spam, so no spam from the Debian list was sent to the wastebin. I'm still working on finding a fix though. The way the ignorelist.db is supposed to work with bogofilter, is that you populate the ignorelist.db with headers from a genuine post from, for instance, the Debian list, then when you check your mail, bogofilter ignores the headers from mail sent from the Debian list, and turns it's attention to the body of the messages, and hopefully will separate the spam from the ham. As I say, I'm still trying to resolve the problem. I'll post back when I've fixed it. After all, it must be possible.
