Case-sensitive Filtering Possible?

[John McGaw]

I have a situation where I need to have a filter make case-sensitive
matches but there seems to be no way to make it pay attention to such
trivialities. What needs to be done is to tell the difference between, for
example 'User...@provider.com' and 'user...@provider.com'. And yes, I
know that email addresses and such are supposed to ignore case but in this
case a prolific spam source has the first version and uses it consistently.
TB's spam filtering is totally hopeless in this (and most other?) regard(s)
and gleefully passes every bit of this spam through while randomly
'junking' good messages and it never seems to learn no matter what I do.
After a year or two it should have learned something, shouldn't it?

While I'm asking questions, why can't the TB user-defined filters do
sensible tests like 'if there are five or more forwards in a header
somebody is trying to hide something so it is probably spam so send it off
to the junk folder'?

For more sophisticated filtering, I would consider a proxy with regex
and wildcards or some kind of add-on.

Native Tbird doesn't do regex or wildcards, which is very limiting.

Can you suggest a proxy which is reliable, easy to set up, and preferably
free? I probably remember enough regex to get me going from my time with
Unix in the days of dinosaurs and dumb terminals although in this situation
a simple 1:1 match would do the job just fine.

Disclaimer: I'm not using any spamfilters currently, Tbird's or other.
When I did, I preferred the SpamPal choices over the Bayesian style,
even tho' SP also had a Bayesian plugin which I didn't use

I once used SpamPal (for email), but I don't know if it is still as well
supported as it was when I used it. It looks like some of its webpages
are now hosted at sourceforge instead of the way it used to be.
http://sourceforge.net/projects/spampal/ some old support

I've never used SpamAssassin

... but I think SpamPal was easier.

I've read some good reviews about some Tbird plugins and there is a lot
of useful info on the page below.
