I get the feeling that most, if not all of the people who
replied to this message mis-interpreted the question (but I guess I might
be...).  Pine does indeed offer filtering.  It's different than what
procmail does, but they still call it filtering.  If you open up the pine
configuration and scroll down a ways, you'll see a couple of options for
"display-filters" and "sending-filters".  A good example of pine filters
is the pinepgp package, which automates pgp signing, key verification,
encryption, and decryption.  I used the attached filter, part of the
pinepgp package, to PGP sign this message.  I don't know anything about
how to write one, but, as you'll see by viewing the attachment, a pine
filter can be a simple shell script.  But I don't know which arguement
to the script is what.  I'd be willing to bet pine filter writing is
documented in the pine-docs package (the contents of which are
also available at ftp://ftp.cac.washington.edu/pine/docs.).
