Hello Steffen,

thank you for creating a test setup. I will try to implement it the way
you did it, but I will stay with maildir.

Meanwhile I have recognized another issue, this time with our webmail
system (roundcube). It seems that it is not able to handle multiple
namespaces so I might need to stay with the single private namespance setup.

Thank you very much for your kind help.

best regards

Andreas
