A disadvantage of using a mysql-based greylisting solutions is you're
reliant on another service which means you're adding an extra point of
failure.
Many of the 'de facto standard' Exim greylisting solutions use some sort
of flat-file backend. Take a look at 'greylistd' and 'postgrey', both
work just fine with Exim 4.
