Your system does not send confirmation e-mails

It appears that no email notifications are being sent. I invited several external users to collaborate on testing and none of them have received emails, checked spam and trash etc. Any time an email is expected to be sent we are seeing no emails sent.

Hi. It's happening to me right now.

Not getting confirmation email when I sign-up without linking to Github or Bitbucket.

Hi, it's happening to me too...
It is been 7 days since...
