This depends on the modifications in the master.cf file.
My last option is to ask if you or anyone else can send me their madter.cf and main.cf (removing the personal content) so I can try a complete working file set on my configuration. If you are willing to share that would be very much appreciated.
Just delete those variables from master.cf you don’t want to override them , you should have all your restrictions set in main.cf
example line from master.cf just delete old one and paste this one:
smtps inet n - y - - smtpd -o syslog_name=postfix/smtps -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes -o smtpd_reject_unlisted_recipient=no -o smtpd_recipient_restrictions= -o smtpd_relay_restrictions=permit_sasl_authenticated,reject -o milter_macro_daemon_name=ORIGINATING
