 New Features in Exim

     contains the cipher used for the delivery. The same is true for
     $tls_peerdn.
 
+ 4. There is now a -Mvc <message-id> option, which outputs a copy of the
+    message to the standard output, in RFC 2822 format. The option can be used
+    only by an admin user.
+
+ 5. There is now a /noupdate option for the ratelimit ACL condition. It
+    computes the rate and checks the limit as normal, but it does not update
+    the saved data. This means that, in relevant ACLs, it is possible to lookup
+    the existence of a specified (or auto-generated) ratelimit key without
+    incrementing the ratelimit counter for that key.
+
+    In order for this to be useful, another ACL entry must set the rate
+    for the same key somewhere (otherwise it will always be zero).
+
+    Example:
+
+    acl_check_connect:
+      # Read the rate; if it doesn't exist or is below the maximum
+      # we update it below
+      deny ratelimit = 100 / 5m / strict / noupdate
+           log_message = RATE: $sender_rate / $sender_rate_period \
+                         (max $sender_rate_limit)
+
+      [... some other logic and tests...]
+
+      warn ratelimit = 100 / 5m / strict / per_cmd
+           log_message = RATE UPDATE: $sender_rate / $sender_rate_period \
+                         (max $sender_rate_limit)
+           condition = ${if le{$sender_rate}{$sender_rate_limit}}
+
+      accept
+
+ 6. The variable $max_received_linelength contains the number of bytes in the
+    longest line that was received as part of the message, not counting the
+    line termination character(s).
+
+ 7. Host lists can now include +ignore_defer and +include_defer, analagous to
+    +ignore_unknown and +include_unknown. These options should be used with
+    care, probably only in non-critical host lists such as whitelists.
