Some users like to archive all the received email on their own system if they use the email service. I have a user whose service was interrupted for some considerable time. They asked if I could send all the emails from the gap. I said no, it’s not supported, and Discourse is really a web forum with a mailing list in parallel on the side only.
Having said that, is there a way to dump out all topics in a given date range by mail to a given user? Or, how to dump out all the topics to a file, and then I could postprocess them with a simple script to send out?
