If you want to enable a filter for specific users, define the filter in
master.cf but do not add the "-o content_filter=xxx" to smtp.

Instead, add an access table to the top of your smtpd_recipient_restrictions like
this :
check_recipient_access hash:/etc/postfix/filter


... and in that table activate the filter :

-- /etc/postfix/filter :

user1@dom.com FILTER filter:dummy
dom2@com FILTER filter:dummy

Remember to do a 'postmap filter' .
