Configuring another email provider for Discourse

[A Former User]

Hi,
The default email server that runs with all Cloudron Apps doesn't work for me because as I read more that half of DigitalOcean IPs are blacklisted.
The quite easy workaround for WordPress was just to use the SMTP plugin with Mailgun.
I would like to do the same thing with Discourse, but you cannot change the email server settings directly in the Discourse UI but must go through the command line as in the following procedure: https://crunchify.com/how-to-configure-mailgun-email-server-on-discourse-forum-correct-way/
I know my away around Docker a bit but need better step-by-step instructions on hope to go into the Discourse container and configure it to run with my Mailgun account. Any help on this would be much appreciated.
Cloudron rocks by the way, this issue has to do with a limitation of DigitalOcean and not Cloudron.
Thanks!

@wexlerj The email relay configuration in Cloudron is at the domain level. Please see https://docs.cloudron.io/email/#relay-outbound-mails . So Email -> Select domain -> Outbound -> Mailgun. And then all apps will automatically use mailgun (not just discourse).
