I'm setting up greylisting on my server right now and while reading over the instructions it appears to be easy to set up, but there doesn't appear to be any details as to how to fine tune greylisting. If say your qmail server is blocking a specific site or domain and you want to allow it because it isn't a spammer.
Anybody have any idea's or input on this since the manuals really don't have anything on fine tuning it? Thanks, My (Alan) Nguyen
