It seems to me that Racket Discourse doesn't have the option for starting new topics via email enabled. When I tried just sending an email, I got a reply with "[Racket Discussions] Email issue -- Unknown To: Address" subject.

A bit of searching yielded this link: How do I use Discourse via email? - FAQs - Mozilla Discourse

But no such icon is present in Racket Discourse topics. Would it be possible to enable it?

Hmm... well, I just spent five minutes searching, and I can't find the relevant setting, if in fact it exists. Let me know if you can find anything on


Okay, yay! Found it.

Down side: there are some things to configure, and some gotchas.

One fundamental issue is that by default, users must be at trust level 2, "member", in order to start new topics. Thinking harder, this is probably a foundational pillar of spam prevention, and I'd be leery about adjusting that.

Second, it looks like there's some configuration work to do around choosing email addresses and even a possible authentication server, ugh.

It's not yet clear to me whether this is required or simply available.

Further investigation required!

Just a quick note

  • you should be able to start new threads(aka topics) by emailing
  • new users can email in. No need to be at β€˜trust level 2’
