The sorting in the according public folder happens in a global sieve script before user scripts are fireing. It is combined with the ‚+‘ notation in postfix for sub addresses and an special ‚listadm‘ user

The sieve script is then reading the generated address and delivers it into the according public folder. We learned a lot about sieve scripting with this task :-)

More details would be to much here.
To be honest, we needed some time to get it done properly. It is a combination of features and A LOT OF testing and analysing the behaviour of postfix/dovecot/public-folder/sieve/acl.
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.
