=head1 NAME
relay_only - this plugin only permits relaying
=head1 SYNOPSIS
# in config/plugins
check_relay
relay_only
# other rcpt hooks go here
=head1 DESCRIPTION
This plugin can be used for the case where a server is used as the smart
relay host for internal users and external/authenticated users, but should
not be considered a normal inbound MX server
It should be configured to be run _AFTER_ check_relay and before other
RCPT hooks! Only clients that have authenticated or are listed in the
relayclient file will be allowed to send mail.
