I am new to the list, new to procmail, and I really don't know all that

mans, and other such things, mostly what has happened is that I have
gotten even more confused than I already was.
I really don't want to do anything all that complex, but I could really
use some help please!
What I want to do is filter out most of my incoming spam from repeat
spammers.
What I currently have in my .procmailrc file is a whole bunch of recipes
that look pretty much like this:
:0
* ^From:(_dot_)*(_at_)mailexcite(_dot_)com
$HOME/mail/filtered
Obviously, though, this recipe only looks at the "From" line. What I
would like to do is have a recipe that searches the entire header for the
given search string.
Also, it would be nice if I could have one recipe that searches for all of
the search strings instead of having a separate recipe for each one (which
makes for a pretty long .procmailrc file).
I use procmail's scoring to do exactly that. You start by setting the
score negative, and add points for every hit on your keyword list (or
subtract them for things you want to whitelist).
One recipe for something like this might be:
:0 H:
* -5^0
* 10^0 @mailexcite\.com
* 10^0 some.other.condition
* 10^0 still_another_condition
. . . etc. . .
* -100^0 Subject: re: uce
$HOME/Mail/filtered
It totals up the score, and if it's greater than zero, it delivers to
$HOME/Mail/filtered. The H indicates to egrep the headers, IIRC.
By using constructs like 10^0, I'm indicating it should only get
scored for the first hit. If I used 10^1, it'd get ten points for
each. If you used "* 10^1 mailexcite.com" instead and
"mailexcite.com" appeared three times in the headers, it'd score 30
points. If you set VERBOSE=ON in your .procmailrc, it'll show you the
scores anyway as it processes the recipe, but that's practically like
cheating. :-)
You should probably read the procmailsc man page before trying this.
Also, be aware that there's the potential to divert mail you didn't
intend to if you don't use some sort of whitelisting.
If you need more than this, e-mail me off-list.
