[Dovecot] xi.rename-it.nl/debian/ dovecot-2.0 sieve problem

[Martin Rozgonski]

Hi, 

i used to use deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.0 main  
to update dovecot 1.2 with debian lenny. I used the convert script to change 
my configuration file. Everything works fine but sieve does not work anymore. 
There is no error in the logs but dovecot simply ignores any filter. 

I checked the documentation/configuration twice and had still no success.
Maybe, this is a known/unknown bug or any suggestions?

Best regards
