Random Words
Been following the threads in the mailing list (this and SA-Talk) for
spam with Random
Words (both in Subject and/or Body). This, apparently, is the only type
of spam that manage to bypass our amavid-new+SA+postfix on a FreeBSD 4.8
box (virii-scanner is DrWeb). However, the threads on this subject died
out two weeks ago; unless I missed a few important threads, there wasnt
a definitive conclusion.

What the most (official)ish stand in combating this sort of Spam? Didnt
see any rules against it in 2.63, and there was a (negative) note on
training the bayes with hundreds of these messages. There's been
discussion of making custom SA rules to training the bayes with all of
these messages/emails, with someone mentioning the later types of these
Spam included punctuations which wasnt accounted for in the rules.

Feedback/pointers in this matter is greatly appreciated.

Thanks

I'm as ish as you can get --
1) Use Bayes -- Bayes catches 99%+ of this spam on the three domains I
manage via SA.
2) I developed some "longwords" rules to enhance even that performance,
and per http://bugzilla.spamassassin.org/show_bug.cgi?id=2970 it looks
like some subset or variation on those rules will be included in the next
release of SA.

I haven't yet taken time to post them on the rules wiki, but they should
be available through the archives (search for longwords), and I can send
them to anyone who needs them.
