I know (but obviously forgot) that there are free ones, but I also know 
that some offer subscriptions.  It may be metered on usage, i.e., if it's
just your personal mail relay vs. one that is shared by hundreds of email
addresses, etc.

I forgot to mention that there's also a blackhole list that checks the
URLs of the embedded links.  This is, among other uses, for the "drive-by"
hacked servers, typically in the Pacific Rim, that host the temporary
online "stores" for offshore pharmacies and such.  I've found it to be
extremely effective, though sadly (?) it also seems to include the
occasional opt-in commercial mailing list.
