I guess Google doesn't care about the spam they send, because this doesn't give them financial losses (if someone would start suing them for spam they send, things may change). On the other hand, they are *convinced* (even if this might not be completely true), that accepting anything that *might be* spam (even if it isn't actually) may harm them financially. So they are over-filtering. By "over-filtering" I mean they are focused more on minimizing the number of errors of the first kind (mistakenly accepting a spam mail) than on minimizing the number of errors of the second kind (mistakenly rejecting, or filing to Spam folder, a non-spam mail). The two goals are a bit contrary to each other - if you try too hard to minimize one, the other goes up. But my opinion is - and always was - that for any decent spam filtering system the second goal should be more important than the first, ie. you should make sure that users miss as little non-spam mails as possible, even at the cost of slight increase on number of spams that go through. However, Google seems to think the other way - they want to filter as much spams (and probable spams) as possible, at the cost of increase in rejected non-spam mails. And probably their users are happy with losing mail anyway as they are not going away (and remember, Google is not only free Gmail, it is also paid tier that many corporations use, and that suffers the same problem...). -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
