Sorry, my initial diagnosis was incorrect.

You already have the fix 20220404. That fix changed a fatal error
into a warning, and returns an EADDRNOTAVAIL error.
> postfix/submission/smtpd[156]: fatal: no SASL authentication mechanisms
The server needs to announce the SASL mechanisms in the EHLO response.
If it cannot reply to EHLO, then I don't see what good it does if
we make this a non-fatal error.
