I am wondering if it would help if I added "Subject" to the list of 
things you could use in rulesets.

Would it be useful?

You would only be able to match against exact strings or regular 
expressions, and I'm not quite sure how I would parse it in the ruleset 
files. Exact strings would be in double-quotes, with '"' characters in 
the string doubled up as a means of escaping them. How I would find the 
end of a regular expression is another matter. I guess it would be 
surrounded with '/' characters, and I would look for the first '/' that 
wasn't preceded by a '\'.

I would have to allow the 'i' on the end of a regexp match at least. 
Matching against a quoted exact string would be a substring match.

It would be available just about anywhere you can use a ruleset, as I 
read the subject line near the point where I read the from and to 
addresses from the envelope.

Multiple "Subject:" lines would be handled by adding them all together 
with a \n newline between each one.

Your comments please....

Jules
