Yes, Google seems to have flipped some switch or pushed some change that takes well established domains and senders from that domain and for reasons that are not well understood written them off as spam. In theory they are getting a huge 'not spam' signal back at HQ but I agree with Linus that they screwed up big time. Stuff they should know wasn't spam and have in the past not classified as spam, now suddenly is. Algorithm update fail.

This started hitting several of my mailing lists a while back. Not just personal servers, but several major web mail providers, most notably Yahoo and AOL. Some theories floated around that it had to do with a change to header/certificates, but I don't recall if I saw any actual confirmation of that.

For some sender's I don't even have the "report as spam" button, even though most of the shit I get from them is ads I didn't ask for. Just because it's from a well recognized company domain.
