Dispatching by selected queue

[massimobianchi]

Hello,
I created a number of different email address, each to dispatch to a differente queue.

In the postmaster settings, i set the "trust=Yes", and "Dispatch by selected queue" to the proper queue, but the emails are dispatched to the default queue.

To achieve the result I have added a postmaster filter rule, but I don't understand what I am missing.

In the syslog no errors or warnings.

Any Idea ?
Thanks,
Massimo
