I am seeing the Discourse setup screen and attempting to send the admin email.
I have configured TXT, MX, and CNAME records for my domain and used the discourse-setup.sh script with the credentials and smtp supplied by mailgun.
In addition I have opened ports for my Google Compute Engine instance with the discourse server on it for HTTP HTTPS and 587 for the SMTP (as configured when I ran the setup script.)
Still no emails.
What gives? Please help. Is there a Slack, IRC or Discourse channel or some other chat as well?
