SYNOPSIS
/usr/local/lib/mh/rcvdist [-form formfile] [switches for postproc] address ... [-help]
/usr/local/lib/mh/rcvpack file [-help]
/usr/local/lib/mh/rcvtty [command] [-form formatfile] [-format string] [-bell] [-nobell] [-newline] [-nonewline] [-biff] [-help]

DESCRIPTION
A receive-mail hook is a program that is run whenever you receive a mail message. You do NOT invoke the hook yourself, rather the hook is invoked on your behalf by your system's Message Transport Agent. See slocal (1) for details on how to activate receive-mail hooks on your system. Four programs are currently available as part of MH, rcvdist (redistribute incoming messages to additional recipients), rcvpack (save incoming messages in a packf'd file), and rcvtty (notify user of incoming messages). The fourth program, rcvstore (1) is described separately. They all reside in the /usr/local/lib/mh/ directory. The rcvdist program will resend a copy of the message to all of the addresses listed on its command line. It uses the format string facility described in mh-format (5). In addition, rcvdist also recognizes the following additional component escape:

Escape	Returns	Description
addresses	string	the addresses to distribute to
The rcvpack program will append a copy of the message to the file listed on its command line. Its use is obsoleted by the "file" action of slocal. The rcvtty program executes the named file with the message as its standard input, and writes the resulting output on your terminal. If no file is specified, or is bogus, etc., then rcvtty will instead write a one-line scan listing. Either the `-form formatfile' or `-format string' option may be used to override the default output format (see mh-format (5)). A newline is output before the message output, and the terminal bell is rung after the output. The `-nonewline' and `-nobell' options will inhibit these functions. In addition to the standard mh-format (5) escapes, rcvtty also recognizes the following additional component escapes:

Escape	Returns	Description
body	string	the (compressed) first part of the body
dtimenow	date	the current date
folder	string	the name of the current folder
Normally, rcvtty obeys write permission as granted by mesg (1). With the `-biff' option, rcvtty will obey the notification status set by biff (1) instead. If the terminal access daemon (TTYD) is available on your system, then rcvtty will give its output to the daemon for output instead of writing on the user's terminal.
