I have a question about the following error message.
You do not have permission to send to this recipient. For

> <XXXXXXXX.com #5.7.1>
The user/users can send and receive to any other address but this particular one.
Background: New 2k domain w/Exchange 2k. All user accounts were recreated and not migrated. Old 5.5 exchange was infested with netsky. 2k Exchange has anti-virus for exchange in place.
Thanks in advance.
