A couple of the latter to highlight: * In Postfix 3.1, by default DANE TLSA records will also be used even when a domain's MX records are not DNSSEC-validated, provided the TLSA records of the MX host are. See: http://www.postfix.org/postconf.5.html#smtp_tls_dane_insecure_mx_policy * The compiled-in non-export Diffie-Hellman parameters for the Postfix SMTP server now employ a 2048-bit rather than 1024-bit "safe-prime" (p = 2*q + 1, with q also prime. To ensure that g=2 generates a subgroup of order q, q is chosen to be 11 mod 24 and p is then 23 mod 24). -- Viktor.
