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…

You should use a transaction mail service like Mailgun, Brevo or Amazon SES. That’s the optimal way to send emails from your forum. See discourse/docs/INSTALL-email.md at main · discourse/discourse · GitHub You may also want to check out: [图片] Troubleshoot email on a new Di…

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…

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.

Greetings from DigitalOcean Support! We understand that you have an application requirement or a business need to enable port 25, 465 and 587. However due to our current policy we are unable to facilitate requests to remove the restriction on this port. We recommend utilizing alternative ports if…

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?

失败消息是什么？

DigitalOcean 是否正在阻止传出邮件，许多其他人也报告了此问题？

您尝试过端口 2525 吗？
