The email in question is neither a PGP nor S/MIME mail - it is a notification mail for a web-based "secure maildrop" service (e.g. McAfee Secure Email Gateway, Cisco Secure Email Encryption Service).

This is a common type of system used by companies to send "encrypted" 
emails, but the terminology is disingenuous. No part of the email message is encrypted, instead it is converted to a web document and transferred over TLS (hence "encrypted").

In short, this has nothing to do with GPG.
