+16. It is now possible to supply a list of domains and/or IP addresses to be
+ lookup up in a DNS blacklist. Previously, only a single domain name could
+ be given, for example:
+
+ dnslists = black.list.tld/$sender_host_name
+
+ What follows the slash can now be a list. As with all lists, the default
+ separator is a colon. However, because this is a sublist within the list of
+ DNS blacklist domains, it is necessary either to double the separators like
+ this:
+
+ dnslists = black.list.tld/name.1::name.2
+
+ or to change the separator character, like this:
+
+ dnslists = black.list.tld/<;name.1;name.2
+
+ If an item in the list is an IP address, it is inverted before the DNS
+ blacklist domain is appended. If it is not an IP address, no inversion
+ occurs. Consider this condition:
+
+ dnslists = black.list.tls/<;192.168.1.2;a.domain
+
+ The DNS lookups that occur are for
+
+ 2.1.168.192.black.list.tld and a.domain.black.list.tld
+
+ Once a DNS record has been found (that matches a specific IP return
+ address, if specified), no further lookups are done. If there is a
+ temporary DNS error, the rest of the sublist of domains or IP addresses is
+ tried. The dnslists item itself defers only if none of the other DNS
+ lookups in this sublist succeeds. In other words, a successful lookup for
+ any of the items in the sublist overrides a defer for a previous item.
+
+17. The log selector queue_time_overall causes Exim to output the time spent on
+ the queue as an addition to the "Completed" message. Like queue_time (which
+ puts the queue time on individual delivery lines), the time is tagged with
+ "QT=", and it is measured from the time that the message starts to be
+ received, so it includes the reception time.
+
+18. It is now possible to use both -bF and -bf on the same command, in order to
+ test a system filter and a user filter in the same run. For example:
+
+ exim -bF /system/filter -bf /user/filter </test/message
+
+ This is helpful when the system filter adds header lines or sets filter
+ variables that are used by the user filter.
+
+19. The Exiscan patch is now merged into the main source. See src/EDITME for
+ parameters for the build.
+
+20. If the key for a dnsdb PTR lookup is not an IP address, it is used
+ verbatim, without component reversal and without the addition of
+ in-addr.arpa or ip6.arpa.
+
+21. Two changes related to the smtp_active_hostname option:
+
+ (1) $smtp_active_hostname is now available as a variable. Its value
+ sticks with the message and is therefore available in routers and
+ transports at delivery time.
+
+ (2) The default for smtp_banner uses $smtp_active_hostname instead
+ of $primary_hostname.
+
+22. The hosts_max_try_hardlimit option (default 50) is added to the smtp
+ transport. Exim will never try more than this number of IP addresses; if it
+ hits this limit and they are all timed out, the message is bounced, even
+ though not all IP addresses may have been tried. Compare hosts_max_try,
+ which is a "soft" limit, because Exim will exceed it when hosts time out.
+ The new limit is a protection against lunatic DNS configurations with
+ hundreds of IP addresses.
