the sieve part seems to be very tricky.
My test is now working with a public folder and I have a
"sieve_before" script in place which works for rules of the
private namespace.

But when the rule shall "fileinto" a public folder, the mail isn't
filtered (moved) and syslog says
dovecot: lmtp(.): Error ... sieve...: Mailbox doesn't exist.

After some tests I found out it always looks in the private (or shared)
namespace for that specfied folder.
Do I miss a config option to let dovecot sieve "fileinto" a public
namespace folder?
I use dovecot version 2.2.13.
