condredirect feeds each new mail message to
program with the given arguments.
program exits 0,
condredirect forwards the mail message to
newaddress, and then exits 99,
so further commands in
.qmail are ignored.
program exits 111,
condredirect exits 111,
so delivery will be retried later.
program exits anything else
(or does not exist),
condredirect exits 0,
so the rest of
.qmail will be processed as usual.
it is not safe for
program to fork a child that
reads the message in the background.
WARNING: If you create a
.qmail file to enable
condredirect, make sure to also add a line specifying delivery to your normal mailbox.
