In the never-ending battle against unwanted email junk, I added a bunch of phishing mail signatures to my mail server. Within 15 minutes, the new rules rejected 2 messages; and another 2 in the next 45 minutes. A small but worthwhile reduction in the deluge.
Update: and if I delay incoming email from Windows machines then lots of inbound connections strangely don't run to completion. :-)
