.TH s/qmail: fastforward 1
.SH NAME
fastforward \- forward mail according to a cdb database
.SH SYNOPSIS
in
.BR .qmail-default :
.B | fastforward
[
.B \-nNpPdD
]
.I cdb
.SH DESCRIPTION
.B fastforward
forwards each incoming message
according to instructions in
.I cdb
created by
.BR setforward .
If there is no forwarding instruction in
.I cdb
for the incoming recipient address,
.B fastforward
will bounce the message.
You can override
.B .qmail-default
with a specific
.BR .qmail-\fIrecipient ;
see
.BR dot-qmail (5).
Warning to system administrators:
Messages do not reach
.B ~alias/.qmail-default
unless they are controlled by the
.B alias
user.
See
.BR qmail-getpw (8).
.B SECURITY WARNING:
If
.I cdb
includes instructions pointing to a mailing list owned by another user,
that user gains some amount of control over
.BR fastforward 's
behavior.
In particular, he can force
.B 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.
.SH "OPTIONS"
.TP 5
.B \-n
No delivery.
.B fastforward
will print a description of its actions,
but will not actually read or forward a message.
.TP
.B \-N
(Default.)
Forward a message as usual.
.TP
.B \-p
Pass through.
If
.B fastforward
does not find the recipient in
.IR cdb ,
it exits 0,
giving the message to further commands in
.BR .qmail-default .
If
.B fastforward
finds the recipient,
it forwards the message and exits 99,
so that further commands are skipped.
.TP
.B \-P
(Default.)
Do not pass through.
If
.B fastforward
finds the recipient,
it forwards the message and exits 0.
Otherwise it bounces the message.
.TP
.B \-d
Use
.B $DEFAULT@$HOST
as the recipient address, or
.B $EXT@$HOST
if
.B $DEFAULT
is not set.
.TP
.B \-D
(Default.)
Use
.B $RECIPIENT
as the recipient address.
.SH VERSION
The original
.B fastforward
verion is 0.51, and the respective
.B fastforward
home page is
.BR http://pobox.com/~djb/fastforward.html .
However, this version is tightly integrated into
.BR s/qmail .
