To be clear, it was not rejecting mail.  The emails were never rejected, but only deferred, as is provided for by the RFC for SMTP.

Every message in the queue has been delivered (or will be).  None will be rejected.

There is a big difference, but not worth any more hijacking of this thread than has already taken place.

Thanks for reinstating the account.

Again - your attention to this matter was greatly appreciated and I thank you for your follow-through and follow-up.
