Answer
ORDB is an acronym for “Open Relay DataBase”. This organisation provides a DNS based Black List (DNSBL) of servers which are believed by ORDB to send unsolicited commercial email or spam.
GMS users who have GMS Anti-Spam installed can use DNSBL services, including ORDB, to help reduce the amount of spam entering their system. For more details on DNSBL, please see Knowledge Base Entry Q0264.
There is no connection between ORDB and Gordano Ltd.. For more information on ORDB, please see their web site.
