I do not know how the above Greylisting is implemented. Once I did some
attempt using the file system as database too (one (empty) file per
connecting IP in some hierarchy). It ate all my inodes (was a small
partition).

So - if it is based on the same idea, make sure to have enough inodes
(df -i).
