-Version 4.81
+Version 4.83
+------------
+
+ 1. If built with the EXPERIMENTAL_PROXY feature enabled, Exim can be
+ configured to expect an initial header from a proxy that will make the
+ actual external source IP:host be used in exim instead of the IP of the
+ proxy that is connecting to it.
+
+ 2. New malware type "sock". Talks over a Unix or TCP socket, sending one
+ command line and matching a regex against the return data for trigger
+ and a second regex to extract malware_name. The mail spoofile name can
+ be included in the command line.
+
+
+Version 4.82
------------
1. New command-line option -bI:sieve will list all supported sieve extensions
Unless you really know what you are doing, leave it alone.
4. If not built with DISABLE_DNSSEC, Exim now has the main option
- dns_use_dnssec; if set to 1 then Exim will initialise the resolver library
+ dns_dnssec_ok; if set to 1 then Exim will initialise the resolver library
to send the DO flag to your recursive resolver. If you have a recursive
resolver, which can set the Authenticated Data (AD) flag in results, Exim
- can now detect this.
+ can now detect this. Exim does not perform validation itself, instead
+ relying upon a trusted path to the resolver.
Current status: work-in-progress; $sender_host_dnssec variable added.
early in reception rather than at the end; this will affect any timestamp
included. The log line showing delivery is recorded before that showing
reception; it uses a new ">>" tag instead of "=>".

+
To support the feature, verify-callout connections can now use ESMTP and TLS.
The usual smtp transport options are honoured, plus a (new, default everything)
hosts_verify_avoid_tls.
for specific access to the information for each connection. The old names
are present for now but deprecated.
- Not yet supported: IGNOREQUOTA, SIZE, PIPELINING, AUTH.
+ Not yet supported: IGNOREQUOTA, SIZE, PIPELINING.
8. New expansion operators ${listnamed:name} to get the content of a named list
and ${listcount:string} to count the items in a list.
- 9. New global option "gnutls_enable_pkcs11", defaults false. The GnuTLS
+ 9. New global option "gnutls_allow_auto_pkcs11", defaults false. The GnuTLS
rewrite in 4.80 combines with GnuTLS 2.12.0 or later, to autoload PKCS11
modules. For some situations this is desirable, but we expect admin in
those situations to know they want the feature. More commonly, it means
through, thus breakage. So we explicitly inhibit the PKCS11 initialisation
unless this new option is set.
+ Some older OS's with earlier versions of GnuTLS might not have pkcs11 ability,
+ so have also added a build option which can be used to build Exim with GnuTLS
+ but without trying to use any kind of PKCS11 support. Uncomment this in the
+ Local/Makefile:
+
+ AVOID_GNUTLS_PKCS11=yes
+
+10. The "acl = name" condition on an ACL now supports optional arguments.
+ New expansion item "${acl {name}{arg}...}" and expansion condition
+ "acl {{name}{arg}...}" are added. In all cases up to nine arguments
+ can be used, appearing in $acl_arg1 to $acl_arg9 for the called ACL.
+ Variable $acl_narg contains the number of arguments. If the ACL sets
+ a "message =" value this becomes the result of the expansion item,
+ or the value of $value for the expansion condition. If the ACL returns
+ accept the expansion condition is true; if reject, false. A defer
+ return results in a forced fail.
+
+11. Routers and transports can now have multiple headers_add and headers_remove
+ option lines. The concatenated list is used.
+
+12. New ACL modifier "remove_header" can remove headers before message gets
+ handled by routers/transports.
+
+13. New dnsdb lookup pseudo-type "a+". A sequence of "a6" (if configured),
+ "aaaa" and "a" lookups is done and the full set of results returned.
+
+14. New expansion variable $headers_added with content from ACL add_header
+ modifier (but not yet added to messsage).
+
+15. New 8bitmime status logging option for received messages. Log field "M8S".
+
+16. New authenticated_sender logging option, adding to log field "A".
+
+17. New expansion variables $router_name and $transport_name. Useful
+ particularly for debug_print as -bt commandline option does not
+ require privilege whereas -d does.
+
+18. If built with EXPERIMENTAL_PRDR, per-recipient data responses per a
+ proposed extension to SMTP from Eric Hall.
+
+19. The pipe transport has gained the force_command option, to allow
+ decorating commands from user .forward pipe aliases with prefix
+ wrappers, for instance.
+
+20. Callout connections can now AUTH; the same controls as normal delivery
+ connections apply.
+
+21. Support for DMARC, using opendmarc libs, can be enabled. It adds new
+ options: dmarc_forensic_sender, dmarc_history_file, and dmarc_tld_file.
+ It adds new expansion variables $dmarc_ar_header, $dmarc_status,
+ $dmarc_status_text, and $dmarc_used_domain. It adds a new acl modifier
+ dmarc_status. It adds new control flags dmarc_disable_verify and
+ dmarc_enable_forensic.
+
+22. Add expansion variable $authenticated_fail_id, which is the username
+ provided to the authentication method which failed. It is available
+ for use in subsequent ACL processing (typically quit or notquit ACLs).
+
+23. New ACL modifer "udpsend" can construct a UDP packet to send to a given
+ UDP host and port.
+
+24. New ${hexquote:..string..} expansion operator converts non-printable
+ characters in the string to \xNN form.
+
+25. Experimental TPDA (Transport Post Delivery Action) function added.
+ Patch provided by Axel Rau.
+
+26. Experimental Redis lookup added. Patch provided by Warren Baker.

Version 4.80
------------
gnutls_require_mac & gnutls_require_protocols are no longer supported.
tls_require_ciphers is now parsed by gnutls_priority_init(3) as a priority
string, documentation for which is at:
- http://www.gnu.org/software/gnutls/manual/html_node/Priority-Strings.html
+ http://www.gnutls.org/manual/html_node/Priority-Strings.html
SNI support has been added to Exim's GnuTLS integration too.
then henceforth you will have to maintain your own local patches to strip
the safeties off.
- 8. There is a new expansion operator, bool_lax{}. Where bool{} uses the ACL
+ 8. There is a new expansion condition, bool_lax{}. Where bool{} uses the ACL
condition logic to determine truth/failure and will fail to expand many
strings, bool_lax{} uses the router condition logic, where most strings
do evaluate true.
Note: bool{00} is false, bool_lax{00} is true.
- 9. Routers now support multiple "condition" tests,
+ 9. Routers now support multiple "condition" tests.
10. There is now a runtime configuration option "tcp_wrappers_daemon_name".
Setting this allows an admin to define which entry in the tcpwrappers
