Another 5.7.1 You do not have permission to send to this recipient error

We're running Exchange 2003 SP2. GFI MailEssentials v12 as spam filter.

A user from an outside company is unable to send a message to a specific user within our domain. They are able to send messages to other accounts in our domain. Other users at the same outside company can send a message to the original intended recipient.  Messages come in fine to other accounts and show up in the logs. The outside account has been added to GFI whitelist and outlook safe sender list. No joy.  Exchange sender, recipient and connection filtering enabled. The outside account is not blocked on our exchange server that I can find.

The bounce message generated from the sending mail server:
bigwig@ourdomain.com on 8/8/2007 1:49 PM

> assistance, contact your system administrator.
>             <their.internal.mail.server.com #5.7.1 smtp;550 5.7.1
> Requested action not taken: message refused

Any help is greatly appreciated.

The message means what it says - the message was refused.
Has the sender showed that it is your server that is rejecting the message?
Do connections from their server show in your logs? Have you used GFI to see whether it is logging the rejection?

Thanks for the reply.
GFI does not log the rejection but does log other messages from the sender to other accounts in our domain.  I see in the smtp log xexch50 - 504 followed sometimes by bdat -250.  I'm not clear why this occurs only with the two accounts -- other accounts on the two domains send and receive fine.
