I (and others from Evolution mailing list) are trying to get to grips with using discourse in a mailing list type way.
One thing I’ve noticed is that the threading information on the emails doesn’t seem to be working. None of the message IDs in the References: header match up with other emails from the topic. I would expect a reply to at least mention the message ID from the messages it’s replying to, but it doesn’t seem to.
Things are made more complex in that I don’t seem to be notified about my own posts - so that any threads that I reply to are essentially broken.
The only consistent threading reference is to the original topic - i.e. <email@example.com> so at least the specific topic seems to stay together - but even that breaks occasionally.
Does anyone seriously use Discourse exclusively by email?
