GMail thinks that Spherical emails are spam. It should be obvious why if you check the attached screenshot... The addresses mismatch or they're not verified to belong to each other or whatever. This should be fixed.

I will change the email address once I can confirm if spheredev.org email can be set up. Meanwhile, users should please set GMail to accept that email address.

I don't think there's a way to do that, or am I missing something? Clicking "not spam" only works for the one email, and only per person, since it's an email coming from a mismatching address (which GMail just automatically marks as a spam mail). I remember having similar issues with my own email address sending automatic Drupal update mails to myself.

I don't get it in my spam folder. Replies to my PM's went straight to my inbox.

Ah, alright. I can assume it was just being weird then?
