Do you want to reject them or eat them and send them to /dev/null ?
If you want to reject them something like this would work:
header_checks = regexp:/etc/postfix/regexp_table
and in /etc/postfix/regexp_table something like:
/^Subject: This is the subject I want to reject REJECT 554
Custom rejection message
