John> I already have two dozen entries.) You'll have a lot of collateral damage. I've worked with a lot of schemes over the years for spamfighting. A lot of spam is sourced inside corporate or educational choke points, meaning that a spam message from inside a company would block all remaining mail from that company. So, for this to work, you really need to time out your blocks no more than an hour or two later, or legit mail will get unnecessarily delayed. -- Randal L.
