fastforward - forward mail according to a cdb database

fastforward forwards each incoming message according to instructions in cdb created by setforward.

       If  there is no forwarding instruction in cdb for the incoming recipient address, fastforward will bounce
       the message.

       You can override .qmail-default with a specific .qmail-recipient; see dot-qmail(5).

       Warning to system administrators: Messages do not reach ~alias/.qmail-default unless they are  controlled
       by the alias user.  See qmail-getpw(8).

       SECURITYWARNING:  If  cdb  includes instructions pointing to a mailing list owned by another user, that
       user gains some amount of control over fastforward's behavior.  In particular, he can  force  fastforward
       to  open any file that you can access, and to read any world-readable file that you own, even if the file
       is in a world-inaccessible directory.

       fastforward - forward mail according to a cdb database

-n   No delivery.  fastforward will print a description of its actions, but will  not  actually  read  or
            forward a message.

       -N   (Default.)  Forward a message as usual.

       -p   Pass  through.  If fastforward does not find the recipient in cdb, it exits 0, giving the message to
            further commands in .qmail-default.  If fastforward finds the recipient, it forwards the message and
            exits 99, so that further commands are skipped.

       -P   (Default.)  Do not pass through.  If fastforward finds the recipient, it forwards  the  message  and
            exits 0.  Otherwise it bounces the message.

       -d   Use $DEFAULT@$HOST as the recipient address, or $EXT@$HOST if $DEFAULT is not set.

       -D   (Default.)  Use $RECIPIENT as the recipient address.
