I already did. Ingo takes the folder separator out of the namespace 
information provided  by dovecot. Which is a slash in my case. It IMP 
(the webmail part) works perfectly and displays everything correctly. If 
I setup a sieve filter to place a mail in a subfolder, ingo creates the 
following:
  fileinto "INBOX/mailinglists/discussion/dovecot";
which dovecot does not understand when an email hist this rule. If I 
however manually change it to
  fileinto "INBOX.mailinglists.discussion.dovecot";

The same rule works fine. Ingo is behaving like it should, sticking to 
the namespace given by the server but the delivery agent does not seem 
to understand slashes as folder separators and gives the following error:
