We have an Exchange 2007 Server having issues sending outbound to 2 companies. Our server passes email to a Barracuda 300 through a smarthost, which scans for content and virus. We are clean on mxtoolbox, SPF record in place RDNS in place, etc.
The rejection emails have a vague 554 error. they are at large companies, so it is difficlult to get to a person who can whitelist us or discuss the issue. The NDRs don't specify any particular problem. Here is a cleaned bounce back:

If you want to send me a test message to alan @ it-eye.co.uk my spam software will reject you if you are not setup properly in any way. If it gets through, then you are either being filtered by content or by IP incorrectly.
