MHMAIL(1mh)                                                        MHMAIL(1mh)

NAME
       mhmail - send or read mail non-interactively with nmh

SYNOPSIS
       mhmail [-help] [-version] [-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]

       mhmail with no arguments is equivalent to inc

DESCRIPTION
       mhmail is intended as a replacement, compatible with nmh, for the stan-
       dard  Berkeley  mail  program (mail or mailx).  nmh is intended for the
       use of programs such as cron, which expect to send mail  automatically.
       It  is also used by some nmh commands to mail error notifications.  Al-
       though mhmail can be used interactively, it is  recommended  that  comp
       and send be used instead, to send messages.

       When  invoked  without arguments, mhmail simply invokes inc to incorpo-
       rate new messages from the user's mail drop.

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

       The -subject switch can be used to specify the "Subject:" field of  the
       message.  "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 AT 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, mh-
       mail  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  ad-
       dresses 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-for-
       mat(5).  Naturally, post will fill in the "Sender:" header correctly.

       The  -headerfield name:value switch adds a header field with the speci-
       fied 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 AT example.com \
            -headerfield 'MIME-Version:1.0' \
            -headerfield 'Content-Type:text/plain; charset=utf-8' \
            -headerfield 'Content-Transfer-Encoding:8bit' \
            recipient AT 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 pro-
       vides 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 to post if -profile is not used, or send
       if -profile is used.

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

SEE ALSO
       dist(1), send(1), mh-format(5), send(1), 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.
