=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.
