.SH NAME
esmtp
\-
libESMTP to Sendmail compatibility interface

.SH SYNOPSIS
\fBesmtp\fR [\fIflags\fR] [\fIaddress ...\fR]
.br
\fBsendmail\fR [\fIflags\fR] [\fIaddress ...\fR]

\fBmailq\fR
.br
\fBsendmail \-bp\fR

\fBnewaliases\fR
.br
\fBsendmail \-bi\fR

.SH DESCRIPTION
\fBEsmtp\fR is a send-only \fBsendmail\fR emulator for machines which normally
retrieve their mail from a centralized mailhub using programs such as
\fBfetchmail\fR.

\fBEsmtp\fR does not attempt to provide all the functionality of
\fBsendmail\fR: it is intended to be used by mail user agents as \fBmutt\fR.

.SH OPTIONS
Most \fBsendmail\fR options are irrelevant to \fBesmtp\fR .  Those marked
``ignored'' or ``default'' have no effect on mail transfer.  Those marked
``unsupported'' are fatal errors.

.TP
\fB\-Ac\fR (ignored)
Use submit.cf even if the operation mode does not indicate an initial mail
submission.

.TP
\fB\-Am\fR (ignored)
Use sendmail.cf even if the operation mode indicates an initial mail
submission.

.TP
\fB\-B\fR \fItype\fR
Set the body type to \fItype\fR.  Current legal values are 7BIT or 8BITMIME.

.TP
\fB\-ba\fR (unsupported)
Go into ARPANET mode.

.TP
\fB\-bd\fR (unsupported)
Run as a daemon.

.TP
\fB\-bD\fR (unsupported)
Same as \fB\-bd\fR except runs in foreground.

.TP
\fB\-bh\fR (unsupported)
Print the persistent host status database.

.TP
\fB\-bH\fR (unsupported)
Purge expired entries from the persistent host status database.

.TP
\fB\-bi\fR (ignored)
Initialize the alias database.

.TP
\fB\-bm\fR (default)
Deliver mail in the usual way.

.TP
\fB\-bp\fR
Print a listing of the queue(s).

.TP
\fB\-bP\fR (unsupported)
Print number of entries in the queue(s); only available with shared memory
support.

.TP
\fB\-bs\fR (unsupported)
Use the SMTP protocol as described in RFC821 on standard input and output.  

.TP
\fB\-bt\fR (unsupported)
Run in address test mode.  

.TP
\fB\-bv\fR (unsupported)
Verify names only \- do not try to collect or deliver a message.

.TP
\fB\-C\fR \fIfile\fR
Use alternate configuration file.

.TP
\fB\-d\fR \fIX\fR (ignored)
Set debugging value to
\fIX\fR.

.TP
\fB\-F\fR \fIfullname\fR
Set the full name of the sender.

.TP
\fB\-f\fR \fIname\fR
Sets the name of the ``from'' person (i.e., the envelope sender of the mail).
This address may also be used in the From: header if that header is missing
during initial submission.  The envelope sender address is used as the
recipient for delivery status notifications and may also appear in a
Return-Path: header.

This address is also used to select from different identities in the
configuration file. 

If no envelope sender is specified in the command line then the default
identity's address is used.

.TP
\fB\-G\fR (ignored)
Relay (gateway) submission of a message.

.TP
\fB\-h\fR \fIN\fR (ignored)
Set the hop count to \fIN\fR.

.TP
\fB\-I\fR (ignored)
Same as \fB\-bi\fR.

.TP
\fB\-i\fR (ignored)
Ignore dots alone on lines by themselves in incoming messages.
This should be set if you are reading data from a file.

.TP
\fB\-L\fR \fItag\fR (ignored)
Set the identifier used in syslog messages to the supplied \fItag\fR.

.TP
\fB\-N\fR \fIdsn\fR
Set delivery status notification conditions to \fIdsn\fR, which can be `never'
for no notifications or a comma separated list of the values `failure' to be
notified if delivery failed, `delay' to be notified if delivery is delayed, and
`success' to be notified when the message is successfully delivered.

.TP
\fB\-n\fR (default)
Don't do aliasing.

.TP
\fB\-O\fP \fIoption\fR=\fIvalue\fR (ignored)
Set option \fIoption\fR to the specified \fIvalue\fR.  This form uses long
names.

.TP
\fB\-o\fR \fIx value\fR (ignored)
Set option \fIx\fR to the specified \fIvalue\fR.  This form uses single
character names only.  

.TP
\fB\-p\fR \fIprotocol\fR (ignored)
Set the name of the protocol used to receive the message.  

.TP
\fB\-q\fR[\fItime\fR] (ignored)
Process saved messages in the queue at given intervals.  

.TP
\fB\-qp\fR[\fItime\fR] (ignored)
Similar to \fB\-q\fItime\fR, except that instead of periodically forking a
child to process the queue, forks a single persistent child for each queue that
alternates between processing the queue and sleeping.

.TP
\fB\-qf\fR (ignored)
Process saved messages in the queue once and do not fork(), but run in the
foreground.

.TP
\fB\-qG\fR \fIname\fR (ignored)
Process jobs in queue group called \fIname\fR only.

.TP
\fB\-q\fR[\fI!\fR]\fBI\fR \fIsubstr\fR (ignored)
Limit processed jobs to those containing \fIsubstr\fR as a substring of the
queue id or not when \fI!\fR is specified.

.TP
\fB\-q\fR[\fI!\fR]\fBR\fR \fIsubstr\fR (ignored)
Limit processed jobs to those containing \fIsubstr\fR as a substring of one of
the recipients or not when \fI!\fR is specified.

.TP
\fB\-q\fR[\fI!\fR]\fBS\fR \fIsubstr\fR (ignored)
Limit processed jobs to those containing \fIsubstr\fR as a substring of the
sender or not when \fI!\fR is specified.

.TP
\fB\-R\fR \fIreturn\fR
Set the amount of the message to be returned if the message bounces.  The
\fIreturn\fR parameter can be `full' to return the entire message or `hdrs' to
return only the headers.  In the latter case also local bounces return only the
headers.

.TP
\fB\-r\fR \fIname\fR
An alternate and obsolete form of the \fB\-f\fR flag.

.TP
\fB\-t\fR
Read message for recipients.  To:, Cc:, and Bcc: lines will be scanned for
recipient addresses.  The Bcc: line will be deleted before transmission.

.TP
\fB\-V\fR \fIenvid\fR
Set the original envelope id.  

.TP
\fB\-v\fR
Go into verbose mode.  

.TP
\fB\-X\fR \fIlogfile\fR
