For MX hosts there is no reason to bother with public CAs, even
when the CA certs are free. Just set the expiration date a few
centuries into the future, and replace the cert when you feel the
key has been around long enough, rather than based on a pre-set
deadline.
For MSAs offering service to Joe Public, sure you'll want a CA-issued
cert.
i only referred to "the interval between expiry is long enough that I
get to learn everything over from first principles every time I have to
replace a cert"
