Your system uses mbox?

Per the documentation, if you are using PHP to access users' files in
their home directories, does the web server really have write access
to those files/directories?

Presumably this is for testing, because it isn't matching what your
requirements are per below.  What version of Server Settings Backend
are you using?  Presumably, version 2.0.  The example configuration in
the filters plugin is out of sync.  Please change %u to %1 and see
what you get.  (Note in the future, if you upgrade Server Settings
Backend, you will need to come back to this and change it to %u
again.)

This is a minor issue you have discovered because your
$default_folder_prefix (in the main SM config.php) is presumably
empty.  I have a fix for that, but this isn't going to matter to you
(code will still execute the same).

This appears to be the main problem.  See above for the fix.

> Are there some configuration guide? or some examples? My purpose is to use plugins to configure /home/%u/.procmailrc file as procmail command do.

As is mentioned several times in the documentation and configuration
files, there is ample documentation and information in the Server
Settings Backend plugin.  More general examples for configuring it can
also be found in the Server Settings plugin.
