 CHECK_RELAY, CHECK_NORELAY, RELAY_ONLY
 
     All 3 plugins are deprecated and replaced with a new 'relay' plugin. The new plugin reads the same config files (see 'perldoc plugins/relay') as the previous plugins. To get the equivalent functionality of enabling 'relay_only', use the 'only' argument to the relay plugin as documented in the RELAY ONLY section of plugins/relay.

 Determine if the connection is denied. Use the I<reject 0> option when first enabling the plugin, and then watch your logs to see what would have been rejected. When you are no longer concerned that valid messages will be rejected, enable with I<reject 1>.
