It's working great for me. I've set whitelisted domains within whitelist_clients and set my delay to =180. My only problem is determining what emails are being blocked vs jus greylisted but I think you said you're working on that solution. I whitelisted people who were popping up on the greylist without actually knowing if they were being blocked. I haven't implemented the spamtrap email yet, mainly because I didn't understand the purpose the first time around. I think I get it now and will do that as well, as I think it could aso be very beneficial. I truly believe the final setup should be within ISPC3->emails->global filters->content filter. After spamassisin/amavisd-new, this would be the final block, right? Lately it seems a simple block is to block anything from a .info domain.
