Email Delivery Can Be Affected by External Service Providers’ DMARC Policies

Overview

Some external email service providers have enabled an email authentication policy intended to help prevent email spoofing (a technique used to forge the "From" address of an email message so that it appears to come from a known sender). However, in some scenarios this email authentication policy can interfere with the delivery of legitimate email messages, including messages addressed to @pitt.edu addresses.
