While most seem to get it, the reply-to vs from is still an issue for some folks replying to messages coming from our discourse forum (either their client or they themselves set the address to the From instead of Reply-To)
So I’m wondering, if there’s any chance of discourse additionally using the References and In-Reply-To headers to see if it contains any known post ids.
Emails seem to contain:
firstname.lastname@example.org To: RemObjects <email@example.com>
(Our forum is setup to use firstname.lastname@example.org,com as reply-to, email@example.com as from. talk@ all goes to the support so that no message gets lost when people reply to the wrong address)
