Uh, every possibly variation of the use of procmail is not going to be
covered in the manpage. This is _basic_ regexp stuff.
Besides regexps, you should get familiar with the procmail FAQ and the
searchable archives of the procmail list, both linked from, of all places:
<http://www.procmail.org>
A brief search of the archives with the keywords:
subject blank empty
returned a plethora of hits, among the top few:
<http://www.xray.mpe.mpg.de/mailing-lists/procmail/2000-11/msg00119.html>
List archives are your friend, and so are the FAQs.
Off the top of my head (because, as I said, these are _basic_ regexps):
# Subject: header not even present!
:0h
* ! ^Subject:
!fwdaddr
# subject header present, but blank (not the same as one with "no subject")
:0h
* ^Subject:[ ]*$
!fwdaddr
The abovementioned archived email contains a few variants on these (#4
being the one you might want to use if you're interested in a single regexp
which should catch _most_ instances).
FTR - if you're interested in catching messages with "no subject" (a
subject string sometimes used by default by some mailers if no subject is
specified -- and there are a few variants of this as well), it'd probably
be a good idea to _NOT_ use that same subject on a post to a mailing list
asking about such things - especially one which is about mail filtering,
where people might actually have filters to ditch your message since from
all appearances, it didn't really include a subject...

Please DO NOT carbon me on list replies. I'll get my copy from the list.
