Quoting Ken Hooper (bighouse(_at_)type2(_dot_)com):
I need to identify messages that have either the word "subject" or have
nothing at all in the subject field. Testing for nothing is puzzling me. I
went through the grep man page and procmailex but didn't see anything
useful. Do the following make sense?
* ^Subject: .*subject
* ^Subject: !.+
How 'bout (untested)
* ^Subject:[ ]+$
Where the $ indicates end of line.
