DESCRIPTION
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 mes
sage 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"

ity.
-h ldaphost
