How to create new discussion topics via e-mail?

I generally prefer to use e-mail, and it’s my understanding that Discourse (the software running this site) can function as a mailing list. However, I haven’t been able to find any documentation that explains how to use e-mail with this forum. (A quick e-mail to "discuss@gohugo.io" just generated a generic response that the e-mail address wasn’t recognized.)

Can anyone point me in the right direction?

@natefinch: Can you help here? I’m not sure about the email settings.

In discourse dashboard: Settings/Emails/reply via email,

you could find options.

However, I can’t upload a picture here.
