.SH NAME
.PP
\fB\fCreplier\fR \- automatically respond to messages
.SH SYNOPSIS
.PP
In \fB\fC\&.qmail\fR:
.PP
.RS
.nf
| replier _dir_ _address_ _prog_
.fi
.RE
.SH DESCRIPTION
.PP
The \fB\fCreplier\fR program changes the working directory to \fB\fC_dir_\fR, executes
\fB\fC_prog_\fR with a message on standard input, and forwards the standard output
from \fB\fC_prog_\fR to \fB\fC_address_\fR\&. It adds a \fB\fCMailing\-List\fR field to the message
headers with the contents of \fB\fC_dir_ /mailinglist\fR\&. It rejects the message if
there is already a \fB\fCMailing\-List\fR field. It adds to the message all fields
listed in \fB\fC_dir_ /headeradd\fR, followed by an appropriate \fB\fCDelivered\-To\fR line.
It deletes from the message any fields with names listed in \fB\fC_dir_
/headerremove\fR\&. It performs its header editing on the output from \fB\fC_prog_\fR\&.
.PP
If \fB\fC_prog_\fR exits 0, then \fB\fCreplier\fR forwards the message to \fB\fC_address_\fR and
exits 99\&. If \fB\fCprog\fR exits 111, \fB\fCreplier\fR exits 111\&. If \fB\fCprog\fR exits anything
else, or does not exist, \fB\fCreplier\fR exits 0.
.PP
The \fB\fCreplier\fR program does not distribute bounce messages: if the environment
variable \fB\fC$SENDER\fR is set, and is either empty or \fB\fC#@[]\fR, then \fB\fCreplier\fR
rejects the message.
.SS Environment variables
.PP
The \fB\fCreplier\fR program supplies several environment variables to \fB\fCprog\fR\&. The
recipient address that caused message processing by \fB\fCreplier\fR has one of two
forms: \fB\fC_inlocal_ \- _request_ @ _domain_\fR, where \fB\fC_inlocal_\fR matches the first
line of \fB\fC_dir_ /inlocal\fR, or \fB\fC_request_ @ _domain_\fR, when \fB\fC_dir_ /inlocal\fR has
an empty first line. In either case, \fB\fCreplier\fR sets the following environment
variables:
.PP
\fBNB\fP : These environment variables are not quoted. They are under the
control of the sender.
.PP
\fB\fC$REQUEST\fR
.PP
The \fB\fC_request_\fR portionh of the recipient address.
.PP
\fB\fC$REQUEST2\fR
.PP
The portion of \fB\fC_request_\fR in the recipient address that follows the first
hyphen.
.PP
\fB\fC$REQUEST3\fR
.PP
The portion of \fB\fC_request_\fR in the recipient address that follows the second
hyphen.
.PP
\fB\fC$REQUEST4\fR
.PP
The portion of \fB\fC_request_\fR in the recipient address that follows the third
hyphen.
.SH EXIT STATUS
.PP
If it encounters a permanent error in handling a message, \fB\fCreplier\fR exits
100\&. If it encounters a temporary error a message, \fB\fCreplier\fR exits 111.
