I've been blocking subnets to the mail server manually for the past 10 days or so. Scan the logs and look at common IP sources for spam. PITA but I've got it under control. One of the earlier schemes I noticed was from .pw and .in top level domains. What I'm seeing now are messages coming from assorted domains but from a common subnet and hosting company - some US based. I've had mail queued up for 20-30 mins before delivery before adding some firewall rules. My mail server is an i5 running Windows Server.
