.SH DESCRIPTION
.B mhmail
.BR nmh .
This program is intended for the use of programs such as
.BR cron ,
-which expect to send mail automatically to various
-users. It is also used by various
+which expect to send mail automatically to various addresses. It is
+also used by various
.B nmh
commands to mail various
error notifications. Although
.PP
When invoked without arguments, it simply invokes
.B inc
-to incorporate new messages from the user's maildrop. When one or more users
-is specified, a message is read from the standard input and spooled to
-a temporary file.
+to incorporate new messages from the user's maildrop.
+.PP
+When one or more addresses are specified, a message is read from the
+standard input and spooled to a temporary file.
.B mhmail
then invokes
-.B post
-with the
-name of the temporary file as its argument to deliver the message to
-the specified user.
+.BR post ,
+by default, with the name of the temporary file as its argument to
+deliver the message to the specified address.
.PP
The
.B \-subject
switch can be used to specify the
\*(lqSubject:\*(rq field of the message.
.PP
+The
+.B \-resent
+switch indicates that the message body is a fully formed message that
+will be resent, as
+.B dist
+would do. For example:
+.PP
+.RS 5
+.nf
+mhmail u2@example.com -resent < `mhpath cur`
+.fi
+.RE
+.PP
By default,
.B mhmail
will read the message to be sent from the
switch. If the standard input has zero
length,
.B mhmail
-will not send the message. You can use the switch
+will not send the message and return with status 1. You can use the switch
.B \-body
-\*(lr\*(rq to force an empty message.
+\*(lq\*(rq to force an empty message.
.PP
Normally, addresses appearing as arguments are put in the \*(lqTo:\*(rq
-field. If the
+field. At least one such address is required when sending a message,
+i.e., if any other switches are supplied. If the
.B \-cc
-switch is used, all addresses following it are
-placed in the \*(lqcc:\*(rq field.
+switch is used, all addresses following it, even if there are
+intervening switches other than
+.BR \-to ,
+are placed in the \*(lqcc:\*(rq field. The optional
+.B \-to
+switch can appear in front of any addresses to signify their placement
+in the \*(lqTo:\*(rq field. The
+.B \-to
+and
+.B \-cc
+switches may be given multiple times.
.PP
By using
.B \-from
.IR addr ,
you can specify the \*(lqFrom:\*(rq header of
-the draft. Naturally,
+the draft. If no
+.B \-from
+switch is used when sending,
+.B mhmail
+will supply a \*(lqFrom:\*(rq header field using the sender's local mailbox,
+see
+.I localmbox
+in
+.BR mh-format (5).
+Naturally,
.B post
will fill\-in the \*(lqSender:\*(rq
header correctly.
+.PP
+The
+.B \-headerfield
+.I name:value
+switch adds a header field with the specified name and value to the
+message. (The
+.I value
+is called the
+.I field body
+in RFC 2822, but that's too easily confused with the message body.)
+There need not be a space after the colon that separates the
+name and value in the argument to this switch. It is usually best to
+enclose the argument in quotes to protect it from the shell. The
+.B \-headerfield
+switch may be given multiple times to add multiple header fields,
+for example,
+.PP
+.RS 5
+.nf
+mhmail -from sender@example.com \\
+-headerfield 'MIME-Version:1.0' \\
+-headerfield 'Content-Type:text/plain; charset=utf-8' \\
+-headerfield 'Content-Transfer-Encoding:8bit' \\
+recipient@example.com
+.fi
+.RE
+.PP
+Note about this example: the
+.B \-attach
+switch causes
+.I MIME-Version
+and
+.I Content-Type
+headers to be added to the message.
+.PP
+The
+.B \-profile
+switch instructs
+.B mhmail
+to use
+.B send
+instead of
+.B post
+to send the message. This allows use of the user's context and aliases.
+.PP
+The
+.B \-attach
+.I file
+switch attaches the specified file to the message. Use of
+.B \-attach
+enables
+.B \-profile
+because
+.B mhmail
+uses
+.B send
+to handle the attachment. It is usually best to enclose the argument
+in quotes to protect it from the shell. The
+.B \-attach
+switch may be given multiple times to add multiple attachments.
+.PP
+The
+.B \-nosend
+option shows the draft file that would be posted/sent on the command's
+standard output but does not post or send it.
+.B \-send
+provides the default behavior of posting or sending the message. It
+can be used to disable
+.BR \-nosend ,
+for example, when using a shell alias.
+.PP
+All other switches are passed on to
+.B post
+if
+.B \-profile
+is not used, or
+.B send
+if
+.B \-profile
+is used.
