We use greylisting for a number of reasons: 1) It gives DNS-based RBLs a chance to catch up with spammers who stay on a given IP address. This makes it more likely that SA will catch the spam. 2) It's very cheap. 3) We are toying with the idea of auto-training greylisted messages that are *not* retried as spam. Basically, this lets us use spammer behaviour to better detect spammer content. We still haven't actually done this yet, but it seems like it might be a good idea.
