Another 5.7.1 You do not have permission to send to this recipient error
Posted on 2007-08-08
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:

Any help is greatly appreciated.
