INNODB tables are a newer table type for MySQL, with transaction 
support.   Personally, I think MyISAM is 100% fine for greylisting, 
given the extremely simple database structure. 

Our mail volume is also around 20,000 message attempts per day; 
relaydelay.pl and MySQL 4.1 are using up less than 5% CPU on a P3/700 
server.  milter-spamc and spamd use a bit more, but still the machine is 
largely idle.
