**WHOOO HOOOOO!** It’s working!! (Self signed)

Some things to note:

- In the code in the post above (15) the certificate has to be named .crt (and not .cert!)
- The hostname when creating the self signed cert should not have ‘www’ in it.
- The pop3 polling host in the Discourse control panel should just have the hostname (so not [mail.domain.com](http://mail.domain.com), just [domain.com](http://domain.com)).

I do have other problems tho 😷 `RateLimiter::LimitExceeded` but at least we’ve moved on a bit!

Hope this thread proves useful for others too 🙂
