Your IP (64.246.187.194) has been blocked due to a bogus helo. Bogus helo indicates that a system provided a falsified IP or name when attempting to send mail to our users. This usually indicates a virus infection on the mail server and we cannot unblock the IP address while the helo reports incorrectly. The system administrator will need clean the system of viruses and worms, and properly configure and secure it before we will unblock.


Now, as far as I can tell, I'm sending a proper HELO with my server's FQDN, and their server is coming back with a nonsense error. According to RFC 821, the error code means:

      553 Requested action not taken: mailbox name not allowed
            [E.g., mailbox syntax incorrect]

And yes, the recipient is a valid recipient, we can email him just fine from Gmail or from our ISP's mail server.


So, that's all to say... any wooly thinking here? Or am I right on in my diagnosis that it's their problem?

It looks that your helo doesn't match your reverse. Maybe you should fix that first and try again. Not sure if that's the problem since I don't know what all they check for related to the helo, but I'd start there.
