I'm going to implement greylisting on my mailserver but not sure what to use.
So is there "de-facto" greylisting software for postfix? Gld? Postgrey? Any software I should not even consider?
Mysql support would be nice but not "must have" functionality, what I need is stable and working solution.
Ofcourse if you think I shouldn't use any greylisting at all you can share your opinion
Currently I'm using few rbl lists and spamassassin and it's working fine but as traffic increases I think that greylisting can help to reduce load on server.
