These domains are all over, and probably they weren't all blocked for the same reason. If you have "550" entries in your /etc/access file, they'll show up on this list. Or if you use a DNSBL, or various other reasons. Make sure you aren't running an open relay, open proxies, or an insecure formmail, any of which can be blood in the water for spammers. -Warren Block * Rapid City, South Dakota USA To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
