Thanks for your reply. I tried that one as well - unfortunately that 
didn't really help a lot. Debug now looks a bit different than before:
(Ofcourse did I try it without the debug option at all as well - but 
with the same result.)

But unfortunately there is no more debug as I was hoping of sa-learn.
I also tried using different Dovecot versons already - but with the same 
result - they all give my MTC a SERVERBUG when I try to move mails with 
the help of the antispam plugin.
