Quoting Pascal Hakim <pasc@redellipse.net>:
Even if we assume that I fell asleep on the page down key while counting 4., and guess that I missed half, we're still talking about blocking over 800 valid messages. 25/37700 works out to be 0.066% of spam not being blocked. It's still annoying of course, as the metric to use is the number of spam messages that make it through rather than the percentage that make it through. SNR and all that.
That is crazy. How is the spam filter that good? On my own server I block a ton of stuff at SMTP time, but an annoyingly high amount of stuff still gets past SpamAssassin. Is the filter processing all this mail regularly trained? I know that we can now report mail in the archive as spam, e.g., if it actually gets through. Has that contributed to an increased level of effectiveness?
