E-mail spam

[mtbc]

This month I have been receiving more spam so I concluded that it is time to risk increasing anti-spam measures. I no longer graylist, partly because it was a hassle to maintain with some large services retrying delivery from a new host each time. Instead, I periodically download lists of miscreants' IP addresses and have the firewall redirect their incoming deliveries to a tarpit. I have now added FireHOL's level 2 list to those I redirect away from my MTA: at least based on a small sample, it includes the IP addresses of many hosts that recently spammed me. I wonder which lists others favor.
