| How i can add a signature in procmail to all my mail's
Procmail is generally set up to work on incoming mail. How to get your
outgoing mail to be filtered through procmail (or any other program --- to do
it with procmail, procmail would have to call cat or sed, so you can just run
cat or sed and not call procmail at all for this task) depends on whether your
MUA or your MTA supports it.
