There are two scallability problems in milter-greylist
1) RAM usage. But if you have a big mail server you can afford to buy more
memory
2) time to dump the database to disk. This could be improved by using
several buckets and dumping to disk bucket by bucket. Or by using an
external database. Or by not dumping at all, which cause the greylist to
be lost on power outtage.

I don't see any other problem you can hit on a bigger setup.
