In theory you can run different imapds with different configurations. It
might be a little tricky due to the sieve scripts being in whatever
namespace is the server default, but it's probably manageable.

It's going to be a pain to deploy at FastMail for historical reasons -
but I would like to switch everyone over to unixhs and altns along with
setting up a new servername to connect to, because then we can support
dots in usernames and sharing across domains, which are both
often-requested features.

The changes in the database format are easy - the hard part is getting
everybody to reconfigure their clients!

So I suspect we will keep the existing endpoint
(mail.messagingengine.com) with compatible behaviour (suppress other
domains, strip domains, regular namespace) and tell new users to use the
new server name so they can see everything else.
