Thinking out loud....
Anyone have contact with thunderbird devs? Could a pop proxy be used to check emails being downloaded by thunderbird on SURBL, then decline to download the ones that hit? Obviously with whitelist bypasses?
Then the user could use a web client to delete spams without downloading? Or whatever.....
