 New Features in Exim
 --------------------
@@ -76,6 +76,85 @@ PH/05 Previously, if "verify = helo" was set in an ACL, the condition was true
       tested the remembered result. Now, if a previous verification attempt has
       not happened, "verify = helo" does it there and then.
 
+PH/06 It is now possible to specify a port number along with a host name or
+      IP address in the list of hosts defined in the manualroute or
+      queryprogram routers, fallback_hosts, or the "hosts" option of the smtp
+      transport. These all override any port specification on the transport.
+      The relatively standard syntax of using a colon separator has been
+      adopted, but there are some gotchas that need attention:
+
+      * In all these lists of hosts, colon is the default separator, so either
+        the colon that specifies a port must be doubled, or the separator must
+        be changed. The following two examples have the same effect:
+
+          fallback_hosts = host1.tld::1225 : host2.tld::1226
+          fallback_hosts = <; host1.tld:1225 ; host2.tld:1226
+
+      * When IPv6 addresses are involved, it gets worse, because they contain
+        colons of their own. To make this case easier, it is permitted to
+        enclose an IP address (either v4 or v6) in square brackets if a port
+        number follows. Here's an example from a manualroute router:
+
+           route_list = * "</ [10.1.1.1]:1225 / [::1]:1226"
+
+      If the "/MX" feature is to be used as well as a port specifier, the port
+      must come last. For example:
+
+           route_list = *  dom1.tld/mx::1225
+
+PH/07 $smtp_command_argument is now set for all SMTP commands, not just the
+      non-message ones. This makes it possible to inspect the complete command
+      for RCPT commands, for example. But see also PH/45 below.
+
+PH/08 The ${eval expansion now supports % as a "remainder" operator.
+
+PH/09 There is a new ACL condition "verify = not_blind". It checks that there
+      are no blind (bcc) recipients in the message. Every envelope recipient
+      must appear either in a To: header line or in a Cc: header line for this
+      condition to be true. Local parts are checked case-sensitively; domains
+      are checked case-insensitively. If Resent-To: or Resent-Cc: header lines
+      exist, they are also checked. This condition can be used only in a DATA
+      or non-SMTP ACL.
+
+      There are, of course, many legitimate messages that make use of blind
+      (bcc) recipients. This check should not be used on its own for blocking
+      messages.
+
+PH/10 There is a new ACL control called "suppress_local_fixups". This applies
+      to locally submitted (non TCP/IP) messages, and is the complement of
+      "control = submission". It disables the fixups that are normally applied
+      to locally-submitted messages. Specifically:
+
+      (a) Any Sender: header line is left alone (in this respect, it's a
+          dynamic version of local_sender_retain).
+
+      (b) No Message-ID:, From:, or Date: headers are added.
+
+      (c) There is no check that From: corresponds to the actual sender.
+
+      This feature may be useful when a remotely-originated message is
+      accepted, passed to some scanning program, and then re-submitted for
+      delivery. It means that all four possibilities can now be specified:
+
+      (1) Locally submitted, fixups applies: the default.
+      (2) Locally submitted, no fixups applied: use control =
+          suppress_local_fixups.
+      (3) Remotely submitted, no fixups applied: the default.
+      (4) Remotely submitted, fixups applied: use control = submission.
+
+PH/11 There is a new log selector, "unknown_in_list", which provokes a log
+      entry when the result of a list match is failure because a DNS lookup
+      failed.
+
+PH/12 There is a new variable called $smtp_command which contains the full SMTP
+      command (compare $smtp_command_argument - see PH/07 above). This makes it
+      possible to distinguish between HELO and EHLO, and also between things
+      like "MAIL FROM:<>" and "MAIL FROM: <>".
+
+TF/01 There's a new script in util/ratelimit.pl which extracts sending
+      rates from log files, to assist with choosing appropriate settings
+      when deploying the ratelimit ACL condition.
