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.
+Version 4.63
+------------
+
+1. There is a new Boolean option called filter_prepend_home for the redirect
+ router. It defaults true, for backward compatibility. If a "save" command in
+ an Exim filter has a relative path for its argument, and $home is defined,
+ it is automatically prepended to the relative path. This action can now be
+ prevented by setting filter_prepend_home false.
+
+2. There is a new acl, set by acl_not_smtp_start, which is run right at the
+ start of receiving a non-SMTP message, before any of the message has been
+ read. (This is the analogue of the acl_smtp_predata ACL for SMTP input.) The
+ result of this ACL is ignored; it cannot be used to reject a message. If
+ you really need to, you could set a value in an ACL variable here and reject
+ based on that in the acl_not_smtp ACL. However, this ACL can be used to set
+ controls, and in particular, it can be used to set control=suppress_local_
+ fixups, which cannot be used in the acl_not_smtp ACL because by the time
+ that ACL is run, it is too late. When the acl_not_smtp_start ACL is run, the
+ sender and recipients are known, so the "senders" and "sender_domains"
+ conditions and $sender_address and $recipients variables can be used.
+ Variables such as $authenticated_ sender are also available. It is possible
+ to specify added header lines in this ACL.
+
+
+Version 4.62
+------------
+
+1. The ${readsocket expansion item now supports Internet domain sockets as well
+ as Unix domain sockets. If the first argument begins "inet:", it must be of
+ the form "inet:host:port". The port is mandatory; it may be a number or the
+ name of a TCP port in /etc/services. The host may be a name, or it may be an
+ IP address. An ip address may optionally be enclosed in square brackets.
+ This is best for IPv6 addresses. For example:
+
+ ${readsocket{inet:[::1]:1234}{<request data>}...
+
+ Only a single host name may be given, but if looking it up yield more than
+ one IP address, they are each tried in turn until a connection is made. Once
+ a connection has been made, the behaviour is as for ${readsocket with a Unix
+ domain socket.
+
+2. If a redirect router sets up file or pipe deliveries for more than one
+ incoming address, and the relevant transport has batch_max set greater than
+ one, a batch delivery now occurs.
+
+3. The appendfile transport has a new option called maildirfolder_create_regex.
+ Its value is a regular expression. For a maildir delivery, this is matched
+ against the maildir directory; if it matches, Exim ensures that a
+ maildirfolder file is created alongside the new, cur, and tmp directories.
+
+
Version 4.61
------------
-PH/01 There is a new global option called disable_ipv6, which does exactly what
- its name implies. If set true, even if the Exim binary has IPv6 support,
- no IPv6 activities take place. AAAA records are never looked up for host
- names given in manual routing data or elsewhere. AAAA records that are
- received from the DNS as additional data for MX records are ignored. Any
- IPv6 addresses that are listed in local_interfaces, manualroute route
- data, etc. are also ignored. If IP literals are enabled, the ipliteral
- router declines to handle IPv6 literal addresses.
-
-PH/02 There are now 20 of each type of ACL variable by default (instead of 10).
- It is also possible to change the numbers by setting ACL_CVARS and/or
- ACL_MVARS in Local/Makefile. Backward compatibility is maintained if you
- upgrade to this release with existing messages containing ACL variable
- settings on the queue. However, going in the other direction
- (downgrading) will not be compatible; the values of ACL variables will be
- lost.
-
-PH/03 If quota_warn_message contains a From: header, Exim now refrains from
- adding the default one. Similarly, if it contains a Reply-To: header, the
- errors_reply_to option, if set, is not used.
-
-PH/04 The variables $auth1, $auth2, $auth3 are now available in authenticators,
- containing the same values as $1, $2, $3. The new variables are provided
- because the numerical variables can be reset during string expansions
- (for example, during a "match" operation) and so may lose the
- authentication data. The preferred variables are now the new ones, with
- the use of the numerical ones being deprecated, though the support will
- not be removed, at least, not for a long time.
-
-PH/05 The "control=freeze" ACL modifier can now be followed by /no_tell. If
- the global option freeze_tell is set, it is ignored for the current
- message (that is, nobody is told about the freezing), provided all the
- "control=freeze" modifiers that are obeyed in the current message have
- the /no_tell option.
-
-PH/06 In both GnuTLS and OpenSSL, an expansion of tls_privatekey that results
- in an empty string is now treated as unset.
-
-PH/07 There is a new log selector called sender_verify_fail, which is set by
- default. If it is unset, the separate log line that gives details of a
- sender verification failure is not written. Log lines for the rejection
- of SMTP commands (e.g. RCPT) contain just "sender verify failed", so some
- detail is lost.
+The documentation is up-to-date for the 4.61 release. Major new features since
+the 4.60 release are:
+
+. An option called disable_ipv6, to disable the use of IPv6 completely.
+
+. An increase in the number of ACL variables to 20 of each type.
+
+. A change to use $auth1, $auth2, and $auth3 in authenticators instead of $1,
+ $2, $3, (though those are still set) because the numeric variables get used
+ for other things in complicated expansions.
+
+. The default for rfc1413_query_timeout has been changed from 30s to 5s.
+
+. It is possible to use setclassresources() on some BSD OS to control the
+ resources used in pipe deliveries.
+
+. A new ACL modifier called add_header, which can be used with any verb.
+
+. More errors are detectable in retry rules.
+
+There are a number of other additions too.
