Difference in Spam getting through Spamhaus-Zen and ClamAV signatures (which include ClamAV, SaneSecurity, MBL, and one other)?
No, delivered spam is about the same # of messages as before. Difference in number of messages getting bounced by Spamhaus-Zen and ClamAV? Down about about 40-50%. Overall mail volume is down by a corresponding amount (so the drop in Zen/ClamAV rejections doesn't mean the messages are leaking through, we're seeing fewer attempts to submit messages, and the drop is all contained within messages that Zen and ClamAV were already protecting us from). Which all translates to: less load on our MX servers. That said, everything isn't all peachy. Last week, after McColo was nuked, we had some malware infect a PC on campus, and it started spewing a ton of spam. We stopped it as soon as we noticed it, but, clearly the fight goes on.
