Hi, Over the last week, my machine (Fedora, SA 3.1.3, qmail, qmail-scanner-queue.pl) has been recieving a fair amount of junk mail which is not being tagged as spam; in fact the total scores are negative.
The messages are simply a random stream of words, with punctuation scattered in them. No HTML, no URLs being advertised, no excessive capitalisation, just meaningless text. The message headers are pretty clean too, apart from the From field being false. As such, SA is finding very little to complain about, and is even lowering the scoring because the bayes filtering deems it to be good. Any thoughts on what I can do about these messages? Even with bayes turned off, they would still fail to score more than say 2 or 3. Each message contains a different paragraph of random text, so it's not possible to pick out keywords; and the messages are coming from dialup machines, so blocking IP isn't going to be very effective. Many thanks, Peter Smith
