I am not receiving emails from the site or the doctor. I noticed that the doctor is using port 465 even though I configured it to use 2525:
==================== YML SETTINGS ====================
DISCOURSE_HOSTNAME=url
SMTP_ADDRESS=smtp.mailgun.org
DEVELOPER_EMAILS=REDACTED
SMTP_PASSWORD=REDACTED
SMTP_PORT=2525
SMTP_USER_NAME=url
LETSENCRYPT_ACCOUNT_EMAIL=REDACTED
==================== MAIL TEST ====================
For a robust test, get an address from URL...
Sending mail to REDACTED . .
Testing sending to email@gmail.com using smtp.mailgun.org:465, username:postmaster@url with plain auth.
======================================== ERROR ========================================
UNEXPECTED ERROR
Net::ReadTimeout
Is this expected? I used the smtp checker and it works with 2525 but times out with 465.
