If only it kept preferences...
I was hoping I found a good replacement to the built-in Mail app (and to other clients as well) and for a few minutes it looked like I did.
Then I realized that, whatever I did trying to map the default folders (trash, archive, etc.) to my own ones on my IMAP server, the app kept resetting to its own defaults and recreating its own folders on my server.
And that made the entire app useless to me.
