outbound emails rejected by 2 companies

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:

Please read through my EE Article on problems sending mail to one or more specific domains as someting may be wrong, although I suspect that all is well and you are being blocked incorrectly.
https://www.experts-exchange.com/articles/Software/Server_Software/Email_Servers/Problems-sending-mail-to-one-or-more-external-domains.html - Currently unavailable, but also available at http://www.it-eye.co.uk/faqs/readQuestion.php?qid=2
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.

I believe the companies rejecting us use Mcafee products and we are on a proprietary Mcafee black list.
