>They all use lots of good text hidden...
I think HMM will detect these mails.
- setup HMM
- move all such files in the right corpus folder !
- run a rebuildspamdb
Forget to detect a spam mail on html tags. This will lead in to a never
ending storry.
Put such a mail in the analyzer - you'll see the words are used by assp
bayes.

Betreff: [Assp-test] block specific pattern
Hi again.
Over the last 3-4 days I've seen a HUGE increase in spam slipping
through. All from lots of different "legit" (compromised) mail
servers/accounts. They all use lots of good text hidden in the
message. The only thing in common is some of the html formatting,
which is what I want to catch.
All of the messages have this at the bottom:
<br><center><a href="http://somedomain.com/abunchofnumbersandletters";><img
src="http://somedomain.com/abunchofnumbersandletters.gif";
border="0"></a></center>
</body>
</html>
The thing that varies is the host name and the series of numbers and
letters. That same hostname and series is repeated in the img tag,
but trailing with a .gif.
I'm fearful of rejecting legit mails that might use this kind of
tracking, but don't know what else to do....
Some users are getting hundreds of these a day.
