Fwd: Quota messages warning

I have dovecot 2.4.5 in a Docker container and warning quota of message
count isn't working.
My quota config:
In storage option works ok, but in case of messages no event success.
Log not show anything and external script is not call, of course.
Any idea?
Best Regards,
Alberto
How are you delivering mail to dovecot?
