I running it here and of the 5 different systems we have used, it has
been by far the most effective.
We are not associated in any way with Cloudmark, just a very happy
user.
May I ask, what domain (part) do you check against, actually? The TLD of the
PTR? And what if no PTR is available? And what of two-level country TLD's?
SURBL ran into similar questions. Not really an SPF issue, to be honest; but
it were nice if cloudmark gave some specs as how to retrieve the domain name
to check against.
