Milter-greylist

Hello.



I noticed some similar software (portgrey) are also capable to adjust 
the minimal count of mails before a client is whitelisted, 
milter-greylist accepts clients after one try, true or false?

And about memory and database, I compile milter-greylist with db4 
support, I understand, that all information are keeped memory and dumped 
for backup into db? But the db file is plain text based, so is it the 
database file at all? And does the dump file rotate ever? And how to 
check the actual memory use?
