Can this user normally send you email, can he send you emails without
attachments, did he try sending it again?

We have an Exchange 2000 Server within our company.  Our users have
Outlook 2000 on thier PCs.  Someone tried to sending me an email with a
file attachment.  I was not able to receive the email with the
attachment.
 The sender instead received a message in their email:

Subject: "Delivery Status Notification (Failure)" with the following
Comment:

The following message to <email address> was undeliverable.  The reason
for this problem:
5.1.0 - Unknown address error 550 - '5.2.1 Message rejected.'

Any ideas of what would cause this or where to start troubleshooting?

Thanks,

Joe

The haggis is unusual in that it is neither consistently nocturnal nor
diurnal, but instead is active at dawn and dusk (crepuscular), with
occasional forays forth during the day and night.
