Sign Up Form Firewall Port

Integrations & API
1

I’m setting up a quite strict firewall proxy on my origin server, accepting only incoming connections from Cloudflare. However, I must put some outgoing ports to send the signup/login email. What’s the protocol I should use and the port?

The port will be dependent on how you’ve set up your email config although it’s typically SMTP over port 587.

If you’re blocking outgoing requests from Ghost just be aware that it can cause issues, for example:

  • embeds won’t work if Ghost can’t make outgoing web connections
  • scheduling won’t work if Ghost can’t make requests to itself
  • newsletter sending won’t work if Ghost can’t make API requests to Mailgun
  • integrations won’t work if Ghost can’t make the webhook requests
