Even before Discourse I recall forum software that managed mailing lists. There was usually a sticky with a message warning forum users that each post is sent out as an email, so be respectful of this and format accordingly should you desire a response. EDIT: I actually don't know if it was forum software or just mailman plugged into the forum somehow.
