Hello everyone, i am running Ghost 1-Click Droplet. It works well but Mailgun configuration doesn’t work properly.

I want to use mailgun not only for newsletter but also for sign in / sign up / password renew… etc. I created a domain in Mailgun, configured all DNS settings and at the end got SMTP and API codes. Api codes in Ghost GUI registered and newsletter function works good.

Then i setup SMTP in config.production.json file and restarted Ghost… When i try to sign up or so, it does not work.

Do i missing something ?

Do you happen to use an european server in Mailgun? Because I had the same problem and after many attempts I got it working by changing the host from to

"mail": {
  "transport": "SMTP",
  "options": {
    "service": "Mailgun",
    "host": "",
    "port": 465,
    "secureConnection": true,
    "auth": {
      "user": "",
      "pass": "password"
