I'm writing this from the mail app in ElementaryOS 7.1. I'm always curious how Preposter.us will handle mail from a new client.
Hoping this goes well because after spending a few days with Elementary on one of my System76 machines (I'll write more about that later) I'm really enjoying it, and it would be awesome it I could use it for blogging.
I'm not sure if this client defaults to HTML or plain text, but I guess we'll find-out soon.
