sean -
thanks for your help! however, i just tried your two main suggestions:
* ^Subject:.* [0-9]+
and
* ^Subject:.*[^ ]*.* [0-9]
and neither worked (when i send an e-mail with 7+spaces then a number in
the subject line, it just sorts it into my inbox as it does regularly). did
you test these our on yours before you sent them? are you positive they
work on your system? i have a bunch of other filters working so i know
procmail is functioning....
thanks so much!!!

Six in succession, versus a total of six or more. There's a difference.

The brackets define a character class, and should contain only one of any
given character. When you see things like [ ] in this list, those
contain a space and a tab. The plus trailing the character class says
"match 1 or more of the previous", so the above would match any messages
with a numeric in the subject which followed a space, such as "staff
meeting at 2pm".
this didn't work and i then tried variations such as:
[snip] - also incorrect. You should read up on regular
expressions. Procmail uses them in the recipes, but they're not some
voodoo that was invented as part of procmail.
Have you tried the direct approach:
* ^Subject:.* [0-9]+
There are six spaces preceeding the numeric class. Now, this would match
spaces at the beginning of the subject as well, though the first character
of whatever followed would have to be numeric. Since you might not want
an abundance of leading spaces to trip your rule, you may want to match
ANYTHING EXCEPT a space before matching the spaces:
* ^Subject:.*[^ ]*.* [0-9]
Also note that the plus which was originally following the numeric class
is gone -- since the line isn't anchored to the end, it is unnecessary -
we want at least one, and any more is fluff, so if you eliminate the plus,
you'll match when you find one, since if theres one, or theren's five,
there will be one to match.
This would say "match anything in the subject up to something that ISN'T a
space, then match anything at all, six spaces, then a number - followed by
whatever (we're not using an EOL anchor to require that the numbers appear
at the VERY end of the line, so anything could follow the number -- more
numbers, letters, whitespace, whatever).
Of course, SPACE in the above examples is very literally a SPACE. If you
wanted to match SPACE or TAB, then you'd replace the individual spaces
with individual character classes containing a space and a tab:
* ^Subject:.*[^ ]*.*[ ][ ][ ][ ][ ][ ][0-9]
Some of the bracketed bits will appear wider in this email, and may be
translated by your email client to be all spaces, but they are indeed all
just a space and a tab.
