Just a stupid question, to avoid the obvious "radio doesn't work? Plug
it in" mistake: did you run "postconf reload" after changing the
configuration file? I presume you did, but I'm still asking :-)

main.cf is unsuspicious at first glance.

How does mail enter your system? Via SMTP? If you're using getmail or
something that injects via "sendmail" command, then the filter is
bypassed since smtpd isn't in the loop.

Looks good, too.

Could you show logging related to a message entering your system the
usual way, all the way from initial submission until final delivery?

Is the script executable?
Do messages remain in the mail queue (check with mailq)?

Note that Postfix and your filter "logger" need not be in the same file,
since Postfix uses the "mail" facility, logger defaults to the "user"
facility (sometimes called "priority" for reasons I don't know). Check
your syslog configuration.
