These are ip addresses that are being rejected by Redhawk.org by our DNSBL (DNS Block List, access.redhawk.org) which is maintained by our SpamHawk® Product. The DNSBL is implemented via Sendmail, if you have legitimate email for Redhawk.org that is being blocked, seek the feedback link on the left side of the Redhawk page and send a message, but you have to leave a way to contact you and the ip address in question. So How did you get on the list? UBE = Unsolicited Bulk Email.
