Hello everyone, I’ve been trying to configure outbound mail on a self-hosted Discourse installation but so far no luck. Even with Namecheap support involved, we couldn’t get it working. Hoping someone here can point out what I’m missing. Setup Hosting: DigitalOcean droplet, Discourse installed v…

What is the failure message? Is digital ocean blocking outgoing mail many others have reported? Have you tried port 2525?

Thank you guys for the replies I appreciate it very much. @pfaffman I am not aware that Digital Ocean is blocking outgoing mail. No i have not tried 2525. After searching for it I stumbled upon an article they block all outgoing mails Why is SMTP blocked? | DigitalOcean Documentation I did a litt…

[이미지] LG1: If they won’t open it I need to look into mailgun, I hope this is free. if you contact their support for account activation, after change to the plan type setting, you should be fine on a free plan [이미지] LG1: Namecheap Private Email I always thought of this being very simil…

Digital Ocean has replied and replied to their mail: ”We’d be happy to explore the possibility by having our Security team take a closer look at unblocking the SMTP ports for you.

In that case, you should switch to using a transactional mail service like Mailgun (100 emails free per day) or Brevo (300 emails free per day). Then, you can switch to using port 2525 in your app.yml file, since that isn’t blocked.

I never experienced in my life my brandnew account gets blocked LOL ”Mailgun: Your account is temporarily disabled.” Is there an alternative SMTP service I can use?

You should use a transaction mail service like Mailgun, Brevo or Amazon SES. That’s the optimal way to send emails from your forum.
