A lot depends on how you're sending the outgoing messages. If a program or a
script is sending them, it can explicitly call procmail to filter the outgo-
ing data (procmail's -m option is perfect for this).
If you're sending it from your own mail user agent, though, that depends:
some mailers (such as Mail, mailx, mh, and mutt) allow the user to specify
a program to handle outgoing mail, but others (such as Elm) do not.

See the sample code for that in the procmailex(5) manual page.
