The RBL monitor service was shut down on 5th of May 2016.

		Feel free to migrate your configuration to other services, for example:

		* https://www.rblmon.com/
		* https://rblwatcher.com/
		* http://rbl-check.org/en/

		or use a tool-based approach using
		
		* https://github.com/matteocorti/check_rbl
		* https://github.com/logic/rblcheck

		So long, and thanks for all the fish,
