.SH SUMMARY
libESMTP to Sendmail compatibility interface
.SH SYNOPSIS
.B esmtp
.RI "[ " flags " ] [ " address " "  ... " ]"
.br
.SH DESCRIPTION
.B Esmtp
is a send-only 
.B sendmail
emulator for machines which normally retrieve their mail
up from a centralized mailhub
using programs such as
.B fetchmail
.
.PP
.B Esmtp
does not attempt to provide all the functionality of 
.B sendmail
: it is intended to be used by other 
mail user agents as 
.B mutt
.

.SH OPTIONS
Most 
.B sendmail
options are irrelevent to 
.B esmtp
. Those marked ``ignored'' or
``default'' have no effect on mail transfer.  Those marked ``unsupported''
are fatal errors.  Those marked ``simulated'' are not errors, but the result
is for the program to exit with an informative message. A sort of fatal
non-error.

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

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

.TP
.BI \-B type
(ignored)
Set the body type to
.IR type .
Current legal values are 
7BIT 
or  
8BITMIME.

.TP
.B \-ba
(ignored)
Go into 
ARPANET 
mode.  All input lines must end with a CR-LF, 
and all messages will be generated with a CR-LF at the end.  
Also, 
the ``From:'' and ``Sender:'' 
fields are examined for the name of the sender.

.TP
.B \-bd
(ignored)
Run as a daemon.

.TP
.B \-bD
(ignored)
Same as
.B \-bd
except runs in foreground.

.TP
.B \-bh
(ignored)
Print the persistent host status database.

.TP
.B \-bH
(ignored)
Purge expired entries from the persistent host status database.

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

.TP
.B \-bm
(ignored)
Deliver mail in the usual way (default).

.TP
.B \-bp
(ignored)
Print a listing of the queue(s).

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

.TP
.B \-bs
(ignored)
Use the 
SMTP 
protocol as described in 
RFC821 
on standard input and output.  
This flag implies all the operations of the
.B \-ba
flag that are compatible with 
SMTP.

.TP
.B \-bt
(ignored)
Run in address test mode.  

.TP
.B \-bv
(ignored)
Verify names only \- do not try to collect or deliver a message.

.TP
.BI \-C file
(ignored)
Use alternate configuration file.

.TP
.BI \-d X
(ignored)
Set debugging value to
.IR X .
.ne 1i

.TP
.BI \-F fullname
Set the full name of the sender.

.TP
.BI \-f name
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.
.B \-f
should only be used 
by ``trusted'' users 
(normally
.IR root ", " daemon ,
and
.IR network )
or if the person you are trying to become 
is the same as the person you are.
Otherwise,
an X-Authentication-Warning header
will be added to the message.

.TP
.BI \-G
(ignored)
Relay (gateway) submission of a message,
e.g., when
.BR rmail
calls
.B sendmail .

.TP
.BI \-h N
(ignored)
Set the hop count to
.IR N .
The hop count is incremented every time the mail is 
processed.
When it reaches a limit, 
the mail is returned with an error message,
the victim of an aliasing loop.  
If not specified, 
``Received:'' lines in the message are counted.

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

.TP
.BI "\-L " tag
(ignored)
Set the identifier used in syslog messages to the supplied
.IR tag .

.TP
.BI "\-N " dsn
Set delivery status notification conditions to
.IR dsn ,
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
.B \-n
(ignored)
Don't do aliasing.

.TP
\fB\-O\fP \fIoption\fR=\fIvalue\fR 
(ignored)
Set option
.I option
to the specified
.IR value .
This form uses long names.  See below for more details.

.TP
.BI \-o "x value"
(ignored)
Set option
.I x
to the specified
.IR value .
This form uses single character names only.  
The short names are not described in this manual page; 
see the
.I "Sendmail Installation and Operation Guide"
for details.

.TP
.BI \-p protocol
(ignored)
Set the name of the protocol used to receive the message.  
This can be a simple protocol name such as ``UUCP'' 
or a protocol and hostname, such as ``UUCP:ucbvax''.

.TP
\fB\-q\fR[\fItime\fR] 
(ignored)
Process saved messages in the queue at given intervals.  
If
.I time
is omitted, process the queue once.
.I Time
is given as a tagged number, 
with 
`s' 
being seconds, 
`m' 
being minutes (default), 
`h' 
being hours, 
`d' 
being days, 
and 
`w' 
being weeks.
For example, 
`\-q1h30m' 
or 
`\-q90m' 
would both set the timeout to one hour thirty minutes.
By default,
.B sendmail
will run in the background.
This option can be used safely with
.BR \-bd .

.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,
sendmail forks a single persistent child for each queue
that alternates between processing the queue and sleeping.
The sleep time is given as the argument; it defaults to 1 second.
The process will always sleep at least 5 seconds if the queue was
empty in the previous queue run.

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

.TP
\fB\-q\fRG name
(ignored)
Process jobs in queue group called
.I name
only.

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

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

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

.TP
.BI "\-R " return
(ignored)
Set the amount of the message to be returned 
if the message bounces.
The
.I return
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
.BI \-r name
An alternate and obsolete form of the
.B \-f
flag.

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

.TP
.BI "\-V " envid
(ignored)
Set the original envelope id.  
This is propagated across SMTP to servers that support DSNs 
and is returned in DSN-compliant error messages.

.TP
.B \-v
Go into verbose mode.  
Alias expansions will be announced, etc.

.TP
.BI "\-X " logfile
(ignored)
Log all traffic in and out of mailers in the indicated log file.
This should only be used as a last resort 
for debugging mailer bugs.  
It will log a lot of data very quickly.

.TP
.B \-\-
Stop processing command flags and use the rest of the arguments as
addresses.
