Guess it's not for everyone.

(Personally, I dislike that my email is stored at Googleplex, and that
I cannot fiddle with the server setup.  Otherwise, it's pretty darn
great.)

So the above "mailboxes=, search=" is not a Dovecot configuration
option but a search performed by an IMAP client, right..  (learning
mode!)

I just misunderstood something basic (see above).

"Creates" as in "the client has to keep track of them client-side, the
server knows nothing about them", right?

Niice..  Can an unmodified MUA be expected to correctly fetch the
individual messages found with INTHREAD?  Or does it need to "switch
folders" or perform other IMAP magic.
