Hi Anton,

If you want to keep the size down, you might wanna decrease the
'timeout' during which greylisted tuples are stored from
milter-greylist default of 5d to 4h or 3h *. This shouldn't cause any
problem, in fact, this is the recommended value from Evan's paper.

* My current understanding, not explicitly supported by
greylist.conf(5), is that with milter-greylist this 'timeout' value
corresponds to the period of time that the greylisting tuples are
stored after the greylist time is already over, e.g. if you have
'greylist 1h' and 'timeout 4h', then the total time the brute force
tuples are stored before being ejected is 5h, not 4 hours as it would
have been with the suggested timeout terminology from the original
whitepaper and some other greylisting implementations.

Cheers,
Constantine.
