Linode is taking immediate and drastic measures. Since yesterday 50 accounts represnting several hundred IPs have been cancelled as fraud for this specific SMTP-enabled-customer plus high IP churn abuse pattern. A new policy will be going into effect today, putting further restrictions on when support may grant outbound-SMTP-filter removal to requesting customers. Would Linode meet the criteria for getting someone from the Linode's Trust and Safety department on this list? Mark -- Mark G.
