Deferred emails to Prodigy-protected and Rackspace-hosted domains

Incident Report for Mailprotector

Identified

Mailprotector resolved a significant reputation issue that affected AT&T and Yahoo domains. As part of that remediation, the volume of emails from affected servers significantly dropped. As the affected servers have been put back into service, some domains using Prodigy (part of AT&T and Yahoo) and Rackspace are deferring email delivery due to the rapid volume change. Mailprotector is mitigating the occurrence of deferrals by metering the volume of affected servers. This process will take several more weeks to reach full resolution.
