Did now. I put '2001:470:xxxx::/48' in my relayclients which reflects my IPv6 network at home and my connecting client was correctly handled as a relay client. So check_relay does the sensible thing and can be relied upon by other plugins. Regards Michael -- It's an insane world, but i'm proud to be a part of it. -- Bill Hicks
