As documented header_checks is not an smtpd(8) feature, it is
a cleanup(8) feature.
The easiest way to give separate treatment to mail from the
internal network versus mail from outside is to use separate
Postfix instances.
Otherwise,
submission inet n - - - - smtpd
-o cleanup_service=submission_cleanup
submission_cleanup unix n ............................ cleanup
-o header_checks=pcre:/etc/postfix/header_checks
would do the job.
