New Features in Exim
--------------------
updated when there is a relatively large batch of changes). The doc/ChangeLog
file contains a listing of all changes, including bug fixes.
+Exim version 4.53
+-----------------
+
+TK/01 Added the "success_on_redirect" address verification option. When an
+ address generates new addresses during routing, Exim will abort
+ verification with "success" when more than one address has been
+ generated, but continue to verify a single new address. The latter
+ does not happen when the new "success_on_redirect" option is set, like
+
+ require verify = recipient/success_on_redirect/callout=10s
+
+ In that case, verification will succeed when a router generates a new
+ address.
+
Exim version 4.52
-----------------
cdb {DB/ratelimits.cdb} \
{$value} {RATELIMIT} }
+ Warning: if you have a busy server with a lot of ratelimit tests,
+ especially with the per_rcpt option, you may suffer from a performance
+ bottleneck caused by locking on the ratelimit hints database. Apart from
+ making your ACLs less complicated, you can reduce the problem by using a
+ RAM disk for Exim's hints directory, /var/spool/exim/db/. However this
+ means that Exim will lose its hints data after a reboot (including retry
+ hints, the callout cache, and ratelimit data).
+
TK/01 Added an 'spf' lookup type that will return an SPF result for a given
email address (the key) and an IP address (the database):
sender='${quote_mysql:$sender_address}'} \
{$value}fail}}}
+PH/04 There are two new options that control the retrying done by the daemon
+ at startup when it cannot immediately bind a socket (typically because
+ the socket is already in use). The default values reproduce what were
+ built-in constants previously: daemon_startup_retries defines the number
+ of retries after the first failure (default 9); daemon_startup_sleep
+ defines the length of time to wait between retries (default 30s).
+
+PH/05 There is now a new ${if condition called "match_ip". It is similar to
+ match_domain, etc. It must be followed by two argument strings. The first
+ (after expansion) must be an IP address or an empty string. The second
+ (after expansion) is a restricted host list that can match only an IP
+ address, not a host name. For example:
+
+ ${if match_ip{$sender_host_address}{1.2.3.4:5.6.7.8}{...}{...}}
+
+ The specific types of host list item that are permitted in the list are
+ shown below. Consult the manual section on host lists for further
+ details.
+
+ . An IP address, optionally with a CIDR mask.
+
+ . A single asterisk matches any IP address.
+
+ . An empty item matches only if the IP address is empty. This could be
+ useful for testing for a locally submitted message or one from specific
+ hosts in a single test such as
+
+ ${if match_ip{$sender_host_address}{:4.3.2.1:...}{...}{...}}
+
+ where the first item in the list is the empty string.
+
+ . The item @[] matches any of the local host's interface addresses.
+
+ . Lookups are assumed to be "net-" style lookups, even if "net-" is not
+ specified. Thus, the following are equivalent:
+
+ ${if match_ip{$sender_host_address}{lsearch;/some/file}...
+ ${if match_ip{$sender_host_address}{net-lsearch;/some/file}...
+
+ You do need to specify the "net-" prefix if you want to specify a
+ specific address mask, for example, by using "net24-".
+
+PH/06 The "+all" debug selector used to set the flags for all possible output;
+ it is something that people tend to use semi-automatically when
+ generating debug output for me or for the list. However, by including
+ "+memory", an awful lot of output that is very rarely of interest was
+ generated. I have changed this so that "+all" no longer includes
+ "+memory". However, "-all" still turns everything off.
