This smells like a feature request to me.

Sounds like this fits under the overall banner of achieving more feature parity with mailing lists.

But even with this change, what if that topic is closed?

Or should sites using discourse as a mailing list replacement opt to have `allow duplicate topic titles` on instead?

Also:

> [@Anon email-in should be able to add multiple posts to a topic](https://meta.discourse.org/t/anon-email-in-should-be-able-to-add-multiple-posts-to-a-topic/20888/4):

> The way other (ticketing) systems handle this is to send an acknowledgement email to the sender. That contains the reply key so replies will get appended to the same topic (ticket).
