=head1 SYNOPSIS
|
|
|
|
This plugin checks the norelayclients config file to see if
|
|
relaying is denied.
|
|
|
|
This allows specific clients, such as the gateway, to be denied
|
|
relaying, even though they would be allowed relaying by the
|
|
relayclients file.
|
|
|
|
=head1 CONFIG
|
|
|
|
config/norelayclients
|
|
|
|
Each line is:
|
|
- a full IP address
|
|
- partial IP address terminated by a dot for matching whole networks
|
|
e.g. 192.168.42.
|
|
|
|
=head1 BUGS AND LIMITATIONS
|
|
|
|
This plugin does not have a more_norelayclients map equivalent
|
|
of the more_relayclients map of the check_relay plugin.
|
|
