Jim Watts - Well what do you know? It did the trick! I downloaded the source tarball for pine 4.21, compiled it and installed it, and now my outgoing attachments are tagged correctly and work correctly when received! Many thanks for your insight - I was spinning my wheels in sendmail, metamail, procmail, and every other kind of mail my man pages could find for me, but updating my pine software did the trick...
