In our scenario sbl-xbl at the MTA plus SURBL blocks 80% of spam... If I add greylisting the result goes up to over 95%. I use Xwall spam filter.
I wish all SMTP servers were greylisting compliant - there are some interesting problems - bummer.
Is anyone else recommending or not recommending greylisting and what are your experiences. Seems like surbl should get more effective over the years but right now it probably only stops 50% of our spam if used by itself.

Hi Paul, sbl-xbl at the MTA plus SURBL use should be an effective combination. It's what I've been recommending to other folks. Preventing spams from even entering your network using spamhaus is quite safe, fast and smart.
