As an ISP we decide the best way to handle spam was to rank and tag so
the user can decide, in this case we must have all tests process so that
the rankings are accurate.  If Scott's team were to add some mechanism
to optionally process portions, that would be fine, at least his team
understands that what makes this possibly the best mail scanning suite
in existence, is the fact that they keep in mind that what works for you
doesn't necessarily work for me (so many other companies ignore that).  

If someone does implement RegEx, it needs to be a limited or specialized
version since they can reprocess a single word many times looking for
the best match (try looking at the theory behind RegEx engines, it can
only be process intensive, especially when compared to simple string
matches like Declude currently uses). They need to not be greedy matches
or better yet support a very small set of rules, an overly simplified
engine could allow for word boundries and whitespace with optional
letters and make word and phrase filters much more powerful.

Interesting point, I hadn't considered tests that add a negative weight.
(Although the default config only comes with two negatives as far as I
know
and I haven't had need to add others). However I think it would be safe
to
make some assumptions in the test process that could cut CPU time and
still
yield the type of accuracy we're used to.  For instance,  its very
likely
you'll have more tests that add to the weight than those which detract.
So
you could skip the detracting tests on those messages which haven't
gathered
enough weight from the adding tests to fail your threshold.  Why bother
if
they're going to pass anyway right?  Along the same line of thought, you
could just stop processing additive tests after your weight threshold
has
been met and simply configure the detracting tests weight values
according
to your threshold.

Thoughts?
