We saw this very recently after a site firewall upgrade. Almost
identical behaviour except the final "\n.\n" was never received so the
message was deferred. We logged a 421 command timeout.
The Cisco device was on our premises, not the remote, and removing the
erroneous "inspect SMTP" made it all go away.
