Subject: check on ordb.org

Go to this page on ordb.org: Find Best Online Casinos, Bonuses & Gambling Guides | Search . There you can check if your ip address is in the ORDB database.

From the logs you posted, I’d say you are in that database. Both receiving SMTP servers won’t accept mail from you, but they use a different message. An SMTP administrator can usually write his own message, so it doesn’t surprise me they are different. BTW, you can do that in Domino, too. On the configuration document, in the blacklist section, you can specify your custom message for blacklisted servers.
