Your system needs append_dot_mydomain=yes in main.cf, because the
new default setting could break mail delivery.

That will break mail deliveries if you don't have append_dot_mydomain=yes
in main.cf. See the warning message above.

If it says "using backwards-compatible default setting
mynetworks_style=subnet" (to prevent mail from suddenly getting
blocked) then you need to set mynetworks_style=subnet in main.cf.
