NAME

       mhmail - send or read mail

SYNOPSIS

       mhmail [-to] addrs ...  [-attach file] [-body text] [-cc addrs ...]  [-from addr]
            [-headerfield name:value] [-subject subject] [-resent] [switches for post ... |
            -profile [switches for send ...]]  [-send | -nosend] [-version] [-help]

       mhmail with no arguments is equivalent to inc

DESCRIPTION

       mhmail  is  intended  as  a  replacement  for  the standard Berkeley mail program (mail or
       mailx), which is compatible with nmh.  This program is intended for the  use  of  programs
       such  as  cron,  which expect to send mail automatically to various addresses.  It is also
       used by various nmh commands to mail various error notifications.  Although mhmail can  be
       used interactively, it is recommended that comp and send be used instead to send messages.

       When invoked without arguments, it simply invokes inc to incorporate new messages from the
       user's maildrop.

       When one or more addresses are specified, a message is read from the  standard  input  and
       spooled  to  a temporary file.  mhmail then invokes post, by default, with the name of the
       temporary file as its argument to deliver the message to the specified address.

       The -subject subject switch can be used to specify the “Subject:” field of the message.

       The -resent switch indicates that the message body is a fully formed message that will  be
       resent, as dist would do.  For example:

            mhmail u2@example.com -resent < `mhpath cur`

       By  default,  mhmail  will  read  the message to be sent from the standard input.  You can
       specify the text of the message at the command line with the -body text  switch.   If  the
       standard input has zero length, mhmail will not send the message and return with status 1.
       You can use the switch -body “” to force an empty message.

       Normally, addresses appearing as arguments are put in the “To:” field.  At least one  such
       address  is  required when sending a message, i.e., if any other switches are supplied. If
       the -cc switch is used, all addresses following it, even if there are intervening switches
       other  than  -to,  are  placed  in the “cc:” field.  The optional -to switch can appear in
       front of any addresses to signify their placement in the “To:” field.   The  -to  and  -cc
       switches may be given multiple times.

       By  using -from addr, you can specify the “From:” header of the draft.  If no -from switch
       is used when sending, mhmail will supply a “From:” header field using the  sender's  local
       mailbox, see localmbox in mh-format(5).  Naturally, post will fill-in the “Sender:” header
       correctly.

       The -headerfield name:value switch adds a header field with the specified name  and  value
       to  the  message.   (The value is called the 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 -headerfield  switch  may  be  given
       multiple times to add multiple header fields, for example,

            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

       Note  about this example:  the -attach switch causes MIME-Version and Content-Type headers
       to be added to the message.

       The -profile switch instructs mhmail to use send instead of  post  to  send  the  message.
       This allows use of the user's context and aliases.

       The  -attach  file  switch  attaches  the  specified  file to the message.  Use of -attach
       enables -profile because mhmail uses send to handle the attachment.  It is usually best to
       enclose  the  argument  in quotes to protect it from the shell.  The -attach switch may be
       given multiple times to add multiple attachments.

       The -nosend option shows the draft  file  that  would  be  posted/sent  on  the  command's
       standard  output  but  does  not  post or send it.  -send provides the default behavior of
       posting or sending the message.  It can be used to  disable  -nosend,  for  example,  when
       using a shell alias.

       All  other  switches are passed on to post if -profile is not used, or send if -profile is
       used.

FILES

       /usr/bin/mh/inc            Program to incorporate maildrop into folder
       /usr/lib/mh/post           Program to deliver a message
       /tmp/mhmail*               Temporary copy of message

SEE ALSO

       dist(1), inc(1), send(1), mh-format(5), post(8)

DEFAULTS

       `-from localmbox'
       `-profile' is enabled by default only with -attach
       `-send'

CONTEXT

       If inc is invoked, then inc's context  changes  occur.   With  the  -profile  switch,  the
       context of send is used.  mhmail does not read the context file itself, so an entry for it
       will be ignored.
