I don’t really like greylisting, as it takes longer for email to get through. What did help without any perceivable loss whatsoever is being extensively strict about SMTP specifications (e.g. proper hostnames in EHLO) and things like PTR records. I really like watching these ‘5xx: Client <something> rejected’ flying by in my mail.info :)
