Cloudron Forum

your config.production.json should work as it is identical to the solution here: https://forum.ghost.org/t/unable-to-invite-new-admin-users-to-account-without-mailgun-setup/56711/11 I had tried it and it is working for me. by default if you set up ghost.example.com cloudron should set up an email account ghost.app@example.com for you, you should use ghost.app@example.com instead of newsletter@example.com.

In the interim, I underwent the business evaluation process at Mailguns. The support staff was amiable, and my blogs received positive feedback. Due to a limitation of nine emails per transmission, I was required to send newsletters in smaller batches.

Glad to be of assistance @wmlutz said in Outbound SMTP (Transactional Email) Stopped Working - Invalid login: 535 Authentication failed: mailgun's transactional email cost which is cents/mo. I don't think I've ever paid anything yet as I've not yet gone over the 1000 free messages a month or whatever it is...

Yes, you’re correct! If you’ve configured Mailgun as a relay on Cloudron, you should use port 587 with STARTTLS for secure email sending. If you're looking for alternatives, I recommend SMTPget and iDealSMTP. Both offer reliable services and can also be easily configured for your email needs.

@girish Mailgun. It hasn't happened again (so far). BTW, the notification error listed only two out of ten domains (all using Mailgun).

@humptydumpty thanks, good to know. We don't automate Mailgun relay yet, so we are not affected.

@girish Awesome thanks.

@girish I originally tried that with no success, I figured that the Ghost CLI command initiated some other process or method

@edapm Personally, I'm all-in with Hetzner, not free but the best value for features I've found, particularly having network DDoS protection as standard. Others recommended include Contabo and Scaleway. If you're getting free (inclusive) stuff from Microsoft then I suppose that's decent. Personally, I'm all GitLab, so anything GitHub is second-choice. I guess there's nothing truly free, including your time, but those are the options I recommend, otherwise it's support tickets to Azure and hope for their ability to allow for port needs.
