Procmail problem

Hello everybody.

I have a problem in setting a mail server in 42.1. I have done it many times in the past in other Suse distributions without problems (at least at the end).
Now Postfix works well and when a message arrives through the port 25 it sends the mail to procmail for delivering. In fact the log says: “… status=sent (delivered to command: /usr/bin/procmail)”. procmail is present in /usr/bin and its procmailrc configuration file is present in /etc containing:

The problem is that nothing arrives into the “new” mail folder and nothing is written into procmail log file.

Is anything wrong or is anything changed in 42.1?

Thanks a lot for any advice.
