Yeah I know about that but the thing I'm trying to avoid is accepting the
emails for processing altogether. When my servers get hammered with 10 or 20
spams a second, processing that trash only to delete it wastes valuable
resources. It's much better to handle it at the MTA and reject there, so as
not to even process the trash.

Through another list I was told to use milter-link, which does exactly what I
want and is currently running on a test server. It's looking good and is
working fine so far. I'll likely put it into production by the end of today.

I know milter-greylist can query IP blacklists (I use that already) but I
wonder if milter-greylist's dnsrbl function can query URI lists like:

multi.surbl.org
multi.uribl.org

?

If it can, then technically speaking, I don't need milter-link at all,
milter-greylist would be able to perform the same function.

Michael.
