rcpt500
is a mail-query server that answers X.500 white pages queries. It is
designed to be run out of your mail system alias file (or the equivalent).
rcpt500
accepts the entire contents (including headers) of an RFC 822
message on standard input. The message is parsed, and a search or help
command found in the Subject: header of message body is recognized and
a reply is sent to the sender.
If you are using
sendmail(8),
you could add the following line to the
aliases(5)
file
(/etc/aliases)
to have
rcpt500
invoked whenever mail is sent to the address namelookup on your host:
namelookup:"|/usr/sbin/rcpt500 -l"

The default values for most of the things you can specify with options
