It would be easier to tell who was at fault with a trace of the
session. My recollection is that the server is responsible for
delivering messages for which it hasn't previously announced an
expunge. Cyrus handles this situation by refcounting the message and
not removing it until no client has a handle on it, so mutt works
quite well with it.
I'm not sure whether or not courier is within the bounds of the IMAP
spec (in the past, it often hasn't been), but of course mutt shouldn't
freeze up anyway.
