   3 New Features in Exim
   4 --------------------
   5
   6 This file contains descriptions of new features that have been added to Exim,
   7 but have not yet made it into the main manual (which is most conveniently
   8 updated when there is a relatively large batch of changes). The doc/ChangeLog
   9 file contains a listing of all changes, including bug fixes.
  10
  11 Version 4.61
  12 ------------
  13
  14 PH/01 There is a new global option called disable_ipv6, which does exactly what
  15       its name implies. If set true, even if the Exim binary has IPv6 support,
  16       no IPv6 activities take place. AAAA records are never looked up for host
  17       names given in manual routing data or elsewhere. AAAA records that are
  18       received from the DNS as additional data for MX records are ignored. Any
  19       IPv6 addresses that are listed in local_interfaces, manualroute route
  20       data, etc. are also ignored. If IP literals are enabled, the ipliteral
  21       router declines to handle IPv6 literal addresses.
  22
  23 PH/02 There are now 20 of each type of ACL variable by default (instead of 10).
  24       It is also possible to change the numbers by setting ACL_CVARS and/or
  25       ACL_MVARS in Local/Makefile. Backward compatibility is maintained if you
  26       upgrade to this release with existing messages containing ACL variable
  27       settings on the queue. However, going in the other direction
  28       (downgrading) will not be compatible; the values of ACL variables will be
  29       lost.
  30
  31 PH/03 If quota_warn_message contains a From: header, Exim now refrains from
  32       adding the default one. Similarly, if it contains a Reply-To: header, the
  33       errors_reply_to option, if set, is not used.
  34
  35 PH/04 The variables $auth1, $auth2, $auth3 are now available in authenticators,
  36       containing the same values as $1, $2, $3. The new variables are provided
  37       because the numerical variables can be reset during string expansions
  38       (for example, during a "match" operation) and so may lose the
  39       authentication data. The preferred variables are now the new ones, with
  40       the use of the numerical ones being deprecated, though the support will
  41       not be removed, at least, not for a long time.
  42
  43 PH/05 The "control=freeze" ACL modifier can now be followed by /no_tell. If
  44       the global option freeze_tell is set, it is ignored for the current
  45       message (that is, nobody is told about the freezing), provided all the
  46       "control=freeze" modifiers that are obeyed in the current message have
  47       the /no_tell option.
  48
  49 PH/06 In both GnuTLS and OpenSSL, an expansion of tls_privatekey that results
  50       in an empty string is now treated as unset.
  51
  52 PH/07 There is a new log selector called sender_verify_fail, which is set by
  53       default. If it is unset, the separate log line that gives details of a
  54       sender verification failure is not written. Log lines for the rejection
  55       of SMTP commands (e.g. RCPT) contain just "sender verify failed", so some
  56       detail is lost.
  57
  58
  59 Version 4.60
  60 ------------
  61
  62 The documentation is up-to-date for the 4.60 release. Major new features since
  63 the 4.50 release are:
  64
  65 . Support for SQLite.
  66
  67 . Support for IGNOREQUOTA in LMTP.
  68
  69 . Extensions to the "submission mode" features.
  70
  71 . Support for Client SMTP Authorization (CSA).
  72
  73 . Support for ratelimiting hosts and users.
  74
  75 . New expansion items to help with the BATV "prvs" scheme.
  76
  77 . A "match_ip" condition, that matches an IP address against a list.
  78
  79 There are many more minor changes.
