Thanks for your response. In part you probably identified the problem.
Apparently an undocumented portion of Microsoft Outlook deals with error
messages that are returned when a message is undeliverable. I was getting
"Error message 554 Message Refused". The mail server was rejecting the
address because it was bad. A transcription error allowed an relatively
unnoticeable character into the address. Since prior mailings had worked,
the address went unchecked. The bad address had been auto-stored in the
contacts folder. No where in the Outlook help or on-line info system is
there any discussion of these errror messages. Thanks.
