Multi-Tenanted Exchange 2010 - 501 5.1.3 invalid address
We have a multi-tenanted Exchange 2010 server and one of our tenants have reported that some (not all) external senders are receiving the following bounce-back >> 501 5.1.3 invalid address even though the addresses are correct.
I've seen the following MS KB article >> http://support.microsoft.com/kb/944302 but I'm not sure it can work in a multi-tenanted environment.
Could someone offer any advice on how to resolve this issue?

Can you post the headers of a failed message?
enable logging on the receive connector(s) and have a look through them to locate the failed messages. check exactly what recipient e-mail address is being provided by the sending server to confirm why it may not exist.
The KB article you noted would only be an issue if the recipients address is missing the details after the @ symbol.

Has it been tried with a single email address instead of sending it to 2 people, just to confirm nothing odd is happening?4
can you e-mail these addresses from your own external account (Hotmail, gmail for example)
did you turn on logging as suggested above to confirm exactly what communication is occurring between the sender & recipient's servers?
Google tried to deliver your message, but it was rejected by the server for the recipient domain democraticprogress.org by mail.c9-it.com. [217.158.56.130].OK, so is 'mail.c9-it.com the correct server for the email domain 'democraticprogress.org'?
