In researching an answer to your question, I came across the following
information on the MSN website:

    2. After given a numeric SMTP error response code between 500 and 599
       (also known as a "permanent non-delivery response"), the sender must
       not attempt to retransmit that message to that recipient.

Microsoft Outlook doesn't follow this rule. Outlook perpetually retries
sending messages which encounter an SMTP permanent error between
500 and 599. How interesting that their on-line e-mail service has
rules that prevent use of the parent company's own products.  <8-)
