[Full-disclosure] Anyone have a reason for 2x the email flow today?

The cause was massive cross-posting to security lists. Just kidding.

Are your numbers pre-filtering or post-filtering? 

Pre-filtering counts are really spam counts, so if your numbers are pre-filtering you are just seeing a basic bot-driven spam run. And basic bot-driven spam runs are far more dramatic than they were a couple of years ago.

I see pre-filtering peaks like that several times per month. December 3 was my most recent spike, with 440,000 messages compared to 270,000 on the 2nd and 4th.
