Numerous vendors and organisations maintain some kind of lookup facility where you can determine if a site is currently blocked, and perhpas in some instances trends such as for how long the block has been in place and the general reason for this being the case, yet I cannot find anything analagous to this for the Cloudmark service.
Examples of what I'm talking about are sites such as:
Does anyone know if there is such a function provided by Cloudmark or Microsoft? (I'm not really expecting the latter, but it's worth asking)
so you want to know the reason why those services are blocking specific domain, am I right?!

No, not specifically - I was just using that as an example of what some sites provide. What I'm really after is proof that can be derived from a body external to ourselves that a remote domain has been classified as untrustworthy by Cloudmark.
To be honest, this is more of a political issue. Right now, if a company has been "blacklisted" and therefore unable to send mail to us, usually the way we're notified is they complain to an executive at our university, who then proceeds to blame us, and the only place we can provide "proof" this isn't the case is from the Forefront output - which is obviously our own system. What we really need is the same kind of basic, external from either Microsoft or Cloudmark that we can send the external company and our own executives to so they can see for themselves that the classification has nothing to do with us and that we're not extracting misinformation from our systems to somehow cover the situation up.
Something as fancy as senderbase.org wouldn't be necessary (though it would be nice), but something basic like the reporting from spamhaus would be ideal. So, what I'm asking is if such a facility already exists for Cloudmark/Microsoft Forefront for Exchange or not.
All it boils down to is that external companies don't want to hear us telling them they have a problem. If we had an external reference to point them to that would go a long way to helping them understand they need to fix up things like invalid or missing SPF information; invalid sending domains (we've had numerous instances where people have the actual server as the sending domain), etc.
Also, it just occurred to me I've posted this in the Exchange forums, where technically it should have been on the Forefront forum, even though it's about Forefront for Exchange - my mistake. If the thread can be moved, I'd appreciate it.
When Forefront rejects an email (as the domain is blacklisted), the sender will get a bounce back with the company that has the domain in the blocklist and an advice to contact them to get it sorted.
Isn't your sender getting a bounce with a similar message?
