I see the same goal far off in the horizon. It's propably the only way
out of the mess. Or perhaps one of two (*).

Even though I'm pretty pleased with how the filtering works today, it
needs continous tuning and tweaking to keep it that way. And I have a
lot other things to do.


(*) The other way out would be if all ISP's that doesn't block smtp/25
from their subscriber networks started doing so. Most unlikely..
