Error on emails forwarded from the State of Florida

General Email Routing

My e-mails forwarded to r[email protected] from r[email protected] originating from the State of Florida Department of Revenue are failing. Other e-mails are forwarding. I do not host a mailserver on blysells.com. How do I fix?

I have the same issue. I forwarded emails to my Gmail. It had been working fine until recently. Most emails are rejected by Google with “transient error (421): 4.7.0”.
