So two hours after clicking on an IMAP folder the contents of that
folder were still not displayed correctly?

This doesn't have any relevance.

Then something is seriously wrong.  The fact that you "forced" the
Wheezy Dovecot package into a Squeeze system may have something, if not
everything, to do with your problem (somehow I missed this fact in your
previous email).

Debian testing/sid packages are compiled against newer system libraries.
 If you check various logs you'll likely see problems related to this.
This is also why the Backports project exists--TESTING packages are
compiled against the STABLE libraries so newer application revs can be
used on the STABLE distribution.  Currently there is no Dovecot 2.x
backport for Squeeze.

I would suggest you thoroughly remove the Wheezy 2.0.15 package and
install the 1.2.15-7 STABLE package.  Read the documentation for 1.2.x
and configure it properly.  Then things will likely work as they should.
