mhmail

MHMAIL(1)							     [nmh-1.5]								 MHMAIL(1)

NAME

       mhmail - send or read mail

SYNOPSIS

       mhmail [addrs ...]  [-body text] [-cc addrs ...]  [-from addr] [-subject subject] [-version] [-help]

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 users.  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  users	is
       specified, a message is read from the standard input and spooled to a temporary file.  mhmail then invokes post with the name of the tempo-
       rary file as its argument to deliver the message to the specified user.

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

       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.	You can use the switch -body "" to
       force an empty message.

       Normally, addresses appearing as arguments are put in the "To:" field.  If the -cc switch is used, all addresses following it are placed in
       the "cc:" field.

       By using -from addr, you can specify the "From:" header of the draft.  Naturally, post will fill-in the "Sender:" header correctly.

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

       inc(1), post(8)

DEFAULTS

       None

CONTEXT

       If inc is invoked, then inc's context changes occur.
