My Gmail outgoing mail has been inoperable since I received this in an email on May 28. The source is as follows: Mail Delivery Subsystem • MAILER-DAEMON@mx0a-001a9a01.pphosted.com
Returned mail: see transcript for details
It looks like a valid system notification yet when I long pressed the document icon it said (,null) I think my email was hijacked in some way by this. It was directed to my [redacted] address which I linked with my Gmail account.
