I did some more tests, and it really seams like the Spam folder is the
only one causing trouble. Between other groups copying/moving mail seems
to work fine, but as soon some new mail gets added to Spam (manually,
downloading new mail from the server works fine), I get the same
problem. Another log file is attached.

Sorry, I think I got your question wrong. The *remote* server is running
Dovecot 1.2.15, the local one is v2.0.8. But this concerns just the
remote side, right?
