While it has been my experience that Google's Gmail service has done a pretty good job of only putting legit spam in my spam folder, this morning I noticed something different.
Forum notifications were now being sent directly to spam, for the first time ever. Even more curiously, when I opened one of the messages, it said this:
Why is this message in Spam? We've found that lots of messages from firstname.lastname@example.org are spam.
The only link it gives underneath is to Google's standard spam policies, and suggests that multiple other users have been reporting similar messages as spam.
What is also strange, is that I have a filter set up specifically for notifications from this forum (topics updates, PM, etc.). This way, all the messages go to their own folder, and everything stays organized. Normally a filter like this is enough to keep these messages out of the spam folder - but I guess not anymore. I'll have to make the filter more specific perhaps, and keep an eye on the spam folder (which is a good idea anyways of course).
Anyhow, just a head's up in case anyone else starts experiencing the same censorship. If anyone knows how I can help 'unreport' it, please share, as it isn't clear just looking at it how to do so.
