As documented at the link you mentioned, the Postfix SMTP CLIENT

"postconf -d config_directory" shows where the postconf command looks for
main.cf (and master.cf).
The settings in mainl.cf then determine the location of other Postfix
program and data files.
It would be worthwhile to find out if

If no-one else posts one, I can post a solution that:
- relies on smtpd_delay_reject=yes to postpone check_policy lookup
until RCPT TO.
- disables the SIZE announcement in EHLO
- diusables the SIZE check in MAIL FROM
- calls check_policy to let postfwd (etc.) reject mail, but that
only works

Postfix does not implement SASL auth. It proxies the bits betwen
the remote SMTP client and (SASL library or Dovecot). If you must
see SASL details, use Dovecot "auth_debug=yes" logging, and run a
tool that acts on that information.

For RECEIVING mail, specify a long smtpd_timeout value, like 1000s
master.cf:
submission .. .. .. .. .. .. .. smtpd
