Hi Mark Thanks for the insight.
Most deferred mails go to remote mx that do use PP internally and have an mx that is branded with their domain. But there are also a good bunch of recievers that have a *.pphosted.com mx. Thos mails to *pphosted.com are now delivered. There were less mails to *.ppe-hosted.com mx but there were no deferred mails there. What do you mean that PDR kicks in deferrals per-customer? Would that affect specific Mail.FROM that would be deferred? Would love to talk to a PP representative to better understand those deferrals.
