The replacements are the ACLs acl_smtp_mime and acl_not_smtp_mime. +JH/03 Upgrade security requirements imposed for hosts_try_dane: previously + a downgraded non-dane trust-anchor for the TLS connection (CA-style) + or even an in-clear connection were permitted. Now, if the host lookup + was dnssec and dane was requested then the host is only used if the + TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority + MXs) will be tried (for hosts_try_dane though not for hosts_require_dane) + if one fails this test. + This means that a poorly-configured remote DNS will make it incommunicado; + but it protects against a DNS-interception attack on it. + +JH/04 Bug 1810: make continued-use of an open smtp transport connection + non-noisy when a race steals the message being considered. + +JH/05 If main configuration option tls_certificate is unset, generate a + selfsigned certificate for inbound TLS connections. + +JH/06 Bug 165: hide more cases of password exposure - this time in expansions + in rewrites and routers. + +JH/07 Retire gnutls_require_mac et.al.
