When you enable “Category mirrors a mailing list”, replies to the email thread will end up in the same topic. See [Configuring incoming email to create new topics or group messages - #21](https://meta.discourse.org/t/start-a-new-topic-via-email-e-mail/62977/21).

It would be very interesting if Discourse could perform a reply all when new messages are posted on the topic though! This would provide a two-way mailing list interface.
