Milter-greylist

Hi,

First of all, thank you very much for creating milter-
greylist.  It really helps a lot.

Now I've got a question.  My MX server gets a lot of
probes from spammers for mail accounts that don't exist.
That is, I have thousands of these in my logs:

Jan 20 00:01:19 [...] <guirre@mydomain>... User unknown
Jan 20 00:01:19 [...] <gulfier@mydomain>... User unknown
Jan 20 00:01:20 [...] <gullit@mydomain>... User unknown
Jan 20 00:01:21 [...] <gummo@mydomain>... User unknown

After installing milter-greylist, all of those are
greylisted:

Jan 20 13:17:44 [...] to <arioch@mydomain> delayed for 00:03:00
Jan 20 13:17:56 [...] to <arjani@mydomain> delayed for 00:03:00
Jan 20 13:18:33 [...] to <arkeen@mydomain> delayed for 00:03:00
Jan 20 13:18:34 [...] to <arkosic@mydomain> delayed for 00:03:00

Those just take up space in the greylist for no reason.
In fact, 99% of the contents of my dump file is from
such useless probes.  And the address harvester might
even come back and probe the same account again.

Is it possible _not_ to greylist those, but reject the
mails permanently (and immediately)?  In other words,
a permanent "User unknow" should take precedence over
temporary greylisting.

Best regards
   Oliver
