Err... No? Whatever gave you that idea? Did you not read my post?
My spam filter caught the original spam, based on such things as sender
address, character set used, adjacent crap characters in subject
(!@#$%^&* etc.) and body, whether the subject is empty or lacks lower
case characters (all caps subjects are seldom legit mail), certain
words in the body and more. None of these are enough to trigger the
filter on their own--that would create far too many false positives.
However, when a follow-up to a previously caught spam is detected
(using the references/in-reply-to header) it is instantly filed as spam.
When the OP reposted the spam he did so with a "legal" subject line,
announcing a (to me) understandable charset, a non-depreciated sender
address and without the references/in-reply-to header that would link it
to the previous spam so I could instantly blackhole it.
Please explain to me, in the light of this information, how I can
improve my spam-detection routines so that I would be able to catch the
original post of this tread. I am genuinely interested to find out how
you think that is possible.
