+JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
+ Server implementation by Todd Lyons, client by JH.
+ Only enabled when compiled with EXPERIMENTAL_PRDR. A new
+ config variable "prdr_enable" controls whether the server
+ advertises the facility. If the client requests PRDR a new
+ acl_data_smtp_prdr ACL is called once for each recipient, after
+ the body content is received and before the acl_smtp_data ACL.
+ The client is controlled by bolth of: a hosts_try_prdr option
+ on the smtp transport, and the server advertisement.
+ Default client logging of deliveries and rejections involving
+ PRDR are flagged with the string "PRDR".
+
+PP/16 Fix problems caused by timeouts during quit ACLs trying to double
+ fclose(). Diagnosis by Todd Lyons.
+
+PP/17 Update configure.default to handle IPv6 localhost better.
+ Patch by Alain Williams (plus minor tweaks).
+ Bugzilla 880.
+
+PP/18 OpenSSL made graceful with empty tls_verify_certificates setting.
+ This is now consistent with GnuTLS, and is now documented: the
+ previous undocumented portable approach to treating the option as
+ unset was to force an expansion failure. That still works, and
+ an empty string is now equivalent.
+
+PP/19 Renamed DNSSEC-enabling option to "dns_dnssec_ok", to make it
+ clearer that Exim is using the DO (DNSSEC OK) EDNS0 resolver flag,
+ not performing validation itself.
