FYI: milter-greylist expires unsuccessful entries in not in 'timeout'
time, but in 'delay + timeout' time (and 'timeout' is only a global
setting). Hence in this context, you're ensuring that tuples from
messages which are indeed spam are going to waste space in your
database longer than those that are less likely to be spam.
