It's true that greylisting has the downsides that you described. But after several years of day to day use, I've found that those problems are fewer and farther between than I expected and often easy to work around. E.g. password reminders, if it doesn't get through immediately wait a minute (that's my greylist window), request another reminder, and that one will generally sail right through. Sometimes things do get delayed though, e.g. receipts from places I've never done business with before. Sqlgrey (the greylist tool I use with postfix) even has support for downloading whitelists from a well known source, so popular things that might cause trouble are automatically handled. Even with it's downsides, given the realities of today's spam saturated Internet, it's easily the most effective tool in my spam toolkit. g.
