Does someone have the name / # handy for the hotmail help line for sysadmins? In researching an answer to your question, I came across the following information on the MSN website: http://advertising.msn.com/adproducts/Email_TechStd.asp 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-) matthew black california state university, long beach
