There is no need to restart or even "reload" Postfix when certificates
change, unless you've left renewal too late, and are already or will
imminently be serving expired certificates.
Most Postfix service processes, in particular all the ones that
make use of private keys and certificates, run for a limited
amount of time and are automatically replaced with newer processes
that use the latest settings.
