This doesn't work, because SENDER won't get expanded. However, by
reversing the strong and weak quotes:
DELIVERY = '|procmail -f "$SENDER" ~/.procmail-tmda'
it will (mostly) work, but the FROM line is often empty instead of saying
"MAILER-DAEMON" as it does the first time through procmail.
The first pass through procmail reports the bounce as being from
"MAILER-DAEMON" but this is somehow stripped off by tmda, so when we
regenerate the FROM line when passing back to .procmail-tmda, it ends up
empty. At least the mail gets delivered, but it won't be able to match
procmail expressions designed to catch MAILER-DAEMON, and may cause other
problems that I haven't thought of yet.
Skipping the -f doesn't work at all with mbox format, since no FROM line
is created. It *will* get appended to the mbox, but can't be read by mailx
or pine, and may in fact cause mbox corruption. It might work with
maildir, but I can't say for sure.
