Here's one thought: have imap.el memorize when was the last command
sent to the server.  And always before sending a command, look whether
more than N seconds have passed since the last command.  If so,
suspect that the server might have timed out and send a no-op
command.  If the no-op command gets a reply soon, all is well.  But if
there is no timely reply to the no-op, assume the connection has been
severed, close it and open a new one.

How's that sound?

(That's what I'm going to do for Tramp which has the same problem.
But since I haven't done it yet, I don't know how it will go.)
