The "smtpd_tls_CAfile" is unused bloat unless you solicit client certificates, and even/especially then should NOT be the standard WebPKI CA bundle (which might go in CApath in some edge cases), but would instead list only a short list of CAs you actually trust and use for acceptable client certificates. -- Viktor.
