I think this commit is related with this.  
[https://github.com/discourse/discourse/commit/ea5c3a3bdc529db59be54c27588e41c7951ea269](https://github.com/discourse/discourse/commit/ea5c3a3bdc529db59be54c27588e41c7951ea269)

If I understand it correctly here

There is no problem if the `smtp_settings` address is `smtp.mailgun.org`. My address is `smtp.eu.mailgun.org`. Maybe this is why I got the errors… 🤔

Thanks 🙂

Thanks for the report, @Don and @RBoy! 🙏

The fix is here. Once merged the error should go away.
