Every now and then our users post complete programs to this site. It is especially important that these contributions don't get lost, so I will collect them here. Some of these programs are intended to demonstrate a programming technique and some are ready to run. As a guideline, the code linked in this thread should be general enough to be useful to a large number of users.

mhmail

mhmail(1)						      General Commands Manual							 mhmail(1)

NAME

       mhmail - send or read mail (only available within the message handling system, mh)

SYNOPSIS

       mhmail [addrs...] [options]

OPTIONS

       Specifies  the  text  of the message. If it is specified, then the standard input is not read.  Specifies addresses to be placed in the cc:
       field of the message.  Specifies the content of the From: header of the draft. The address given is placed in the From: field of  the  mes-
       sage.  The  Sender:  field is filled in correctly by post.  Prints a list of the valid options for this command.  Specifies the mail system
       over which mail is sent. The only value allowed is smtp, which is the standard mail system.  Additional values are supported only  for  use
       with other mail systems.  Provides the text of the Subject: field of the message.

DESCRIPTION

       The  mhmail  program is intended as a replacement for the standard mail programs, bellmail and ucbmail. See binmail(1) and mail(1) for more
       details of these mail programs. 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. The mhmail program then
       invokes post with the name of the temporary file as its argument to deliver the message to the specified user.

       Normally, people will use comp and send to send messages.

RESTRICTIONS

       Messages with a null body part will not be sent by mhmail.  You must include some body text in all messages to be sent by mhmail.

       For this version, the -mts option only supports the value smtp. Additional values are supported for use only with other mail systems.

FILES

       Program to incorporate a maildrop into a folder.  Program to deliver a message.	Temporary copy of message.
