Oh, I see now; fastforward is a program that I specify to be called in
.qmail-default. I thought it was a patch to be applied to qmail.
So it would still have the overhead of having to read a message from
qmail, and then write that message back to qmail. That overhead would be
unavoidable if I'm doing program delivery, I guess.
I wonder if in the future, they'll make an "alias delivery" option in
qmail; that is, it calls an external program, but instead of sending the
entire message to the program, it just sends the "RCPT TO:" address to the
program and the program returns to it which mailbox(es) should be
delivered to. Then again, this could turn out to be an ugly piece of
'feature creep'.
