I am on a network running Microsoft Backoffice (I think) and XP
Professional on our workstations. Last week we statred rejecting or
bouncing incoming emaild from certain addresses. They faxed us the
message which says "this message was rejected due to the current
administrative policy by the destination server."

We have not changed any settings or done anything different. Any help
would be appreciated. Thanks.

You may want to talk to the person who set up your server software, as they'll
be more trained in Exchange administration to figure out what the problem
is.

Regardless, it's not an Outlook issue. It may be at your ISP level, it may
be at the server level, but it's not an Outlook problem.
