When invoked without arguments, it simply invokes inc(1) 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(8) with the name of the temporary 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. ^/usr/bin/inc~^Program to incorporate maildrop into folder ^/usr/lib/nmh/post~^Program to deliver a message ^/tmp/mhmail*~^Temporary copy of message None inc(1), post(8) None If inc is invoked, then inc's context changes occur.
