Currently the Community Mailbot only forwards the first post of a topic to the corresponding email lists. Sometimes we want to also forward a reply (for example: a downtime announcement, and then a follow-up resolution announcement).
Here's a solution: we can designate a tag that can be added to a post. Mailbot will look for that tag, and forward that reply.
Note that this won't be a regular Discourse tag, which applies at the topic level. Instead, this tag needs to be in the message body of a reply. Something like #mailbotreply. The Mailbot would then need to look at the full text of posts.
