Hmm, I'd think it a good move to post some statistics, including possible false positives. The problem is ID'ing them, of course; if we're talking any substantial volume of mail then the manpower (I don't know of any automated HAM detector apart from a SPAM/HAM comparator, which is what they're presumably using already) would be substantial.
Do you know what their philosophy is? Proactive, or reactive? Do they just throw it away?
Or, what do they use?
Currently, spam fighting for my few domains and limited number of users costs me an hour or so per day. But, that's PROactive time, mostly spent in blocking senders and reporting the guilty. Other than that, some of our users are "on their own" in re: filtering.
I'm hoping to get one setup for all, but only one ... which means we'll have to migrate delivery/MX addresses for some domains to another address.
But, yeah...I wonder how many legit emails don't make it through? I think email has now come full circle where heavy users don't really care if something doesn't get through. If it's important enough a phone call will be made.
That rings true with our experience. As we've begun blocking larger sets of dynamic and generic DNS zones, every once in a while we found some fairly small outfit with a mailserver but no PTR records ending up blocked. Our clients who are their correspondents were pretty quick to let us know they weren't getting through....
