First of all, it is great to get this discussion on this topic.

Snoozing should work on all (probably except nntp as it is read only?)
backends. But what about the approach which Mailbox is using,
i.e. moving the messages from the inbox into another folder (called "Later"?), and storing
metadata (which folder the message is from, when it is due, ...) in the
registry? The querying of the registry could be timed (every x minutes),
and when due, the message could be moved back to it's original location.

The advantage of this approach is that snoozed messages can also be
checked from other mail programs (I am thinking about an imap backend
for gmail), although only with missing information on due dates / times.

Cheers,

Rainer
