After upgrading from 22.04 to 24.04, postfix sasl authentication is broken.
I see lots of these:
postfix/smtps/smtpd[17393]: warning: SASL authentication failure: cannot
connect to saslauthd server: No such file or directory
It looks like someone had the same problem:
https://serverfault.com/questions/1159702/saslauthd-service-not-
starting-after-upgrade-to-ubuntu-24-04
/etc/default/saslauthd looks correct, postfix is chrooted.

The systemd unit for salsauthd is *disabled* for some reason.

I will try to dig further and amend the report with my findings.
