It could be a side effect of Verisign's "this domain doesn't exist, would you like to buy it?" shenanigans. It's hard to test that a domain exists when you're no longer getting useful responses. That could break quite a few spam filters.

Yesterday my average of around 800 mails a day, dropped to roughly 200. It has been a pain as I don't know what my MB limit is on my POP account. So I've written a bounce deletion script.
