I read somewhere that Discourse supports a mailing-list-style interface.
(hopefully including such things as: Receive posts/replies via email , send posts/replies via email )
Is that correct?
Is it possible to get that activated here? (or is it already?)
You should already receive replies by email as far as I understand (so hopefully you’ll get this one!). I’m not sure about posting through email, but you can try to reply to this and see what happens!
As @reosarevok says, you should already receive replies to your e-mail (unless you went and disabled that in your preferences), but it is not currently possible to post to Discourse by e-mail. I hope to get this set up, but e-mail is always tricky.
Note that you can “watch” categories and get e-mails for all topics and replies to those topics without having to watch the topics individually.
