I would like to know how the option to choose between "reply to author" or "reply to all" could be triggered in email clients of the users who receive notifications from Discourse.
Currently, every message comes from the same "do not reply" address, addressing only the recipient.
I would like to read opinions on whether a naive approach using author_of+{reply_id}@my.discourse as the sender and multiple addresses as recipients (the real recipient and a audience_of+{reply_id}@my.discourse) would allow users to choose recipients (author or all) in their clients (in a scenario with email-receiver).
