Milter-greylist

Hi all!

Just learning how to use milter-greylist. I'm making progress, but
have something I don't understand. Given these definitions in the
greylist.conf file:

        list "greydomains" domain { megabulkmessage/[0-9]*/.com }

and

        racl blacklist list "greydomains" spf self

without the "spf self" most of the megabulkmessage-originated messages
come back with a valid SPF...

I still find things from megabulkmessage***.com being greylisted. for
example:

begin 644 /dev/stdout
M3V-T(#(Q(#$R.C4X.C`V(&9C<VAO;64@;6EL=&5R+6=R97EL:7-T.B!S;69I

`
end

I had thought that being blacklisted would cause the milter to just
drop the message. apparently I'm wrong about that, or have something wrong
in my greylist.conf file.

I'd appreciate some advice on this. Thanks in advance for your help! :)

PS:
Though I'm still working on the best way to configure milter-greylist,
I'm already seeing a LOT less spam than I was. (I've had the same email
address and domain since somewhere around 1995, give or take, so I'm
well known to all the spammers.)
