I am getting this error in the mail_logs on just a few incoming connections... After this error the connection is lost and the sending SMTP server is unable to send e-mail to us. Any idea what this is and how I correct it?

Note I have an appliance with built-in SSL inspection (not a single appliance).
Appreciate your detailed answer.
Thanks,
