I regard greylisting as almost essential these days, even if only done selectively. Experience here is that the SBL-XBL is amazingly trustworthy, so good I currently use it as a Yes/No block before greylisting, or anything else. I'm always wary of statistical filters that stick email in a spam folder, especially the really good one like spamassassin, as when they go wrong the email is effectively quietly lost. If the filter is bad and one is forever rescuing stuff from the spam folder, then you might as well use the delete key instead. One should aim to reject spam before the SMTP transaction completes, so the false positives get returned to sender (rather than lost in a "possible spam" folder).
