Block list service provider must be identified.
Medium Severity
<VulnDiscussion>Block List filtering is a sanitization process performed on email messages prior to their arrival at the destination mailbox. By performing this process at the email perimeter, threats can be eliminated outside the enclave, where there is less risk they can do harm. Block List Services (sometimes called Reputation Data Services) are fee based data providers that collect the IP addresses of known SPAMmers and other malware purveyors. Block List Service Subscribers benefit from more effective SPAM elimination, which has been estimated as comprising up to 90% of inbound mail volume. Failure to specify a Block List provider risks that manual email administration effort would be needed to maintain and update larger block lists than a single email site administrator could conveniently or accurately maintain. The 'Block List' Services vendor provides a value for this field, usually the DNS suffix for their domain.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
