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.
