The easiest may be to use a TCP socket for the dovecot auth service:
/etc/postfix/main.cf:
smtpd_sasl_path = inet:127.0.0.1:12345
and to configure Dovecot accordingly.
I found a very old posting for how to configure dovecot to open
multiple auth sockets in
https://dovecot.org/pipermail/dovecot/2013-August/091960.html
This could be used to open a socket under every Postfix queue
directory.
