I guess this problem was generated by one of this patches:
http://www.dovecot.org/list/dovecot-cvs/2006-June/005915.html
http://www.dovecot.org/list/dovecot-cvs/2006-June/005917.html
http://www.dovecot.org/list/dovecot-cvs/2006-June/005918.html
http://www.dovecot.org/list/dovecot-cvs/2006-June/005919.html

So, with dovecot-20060620.tar.gz or dovecot-20060621.tar.gz you will 
have this problem. Try dovecot-20060619.tar.gz. It works great for me.
