improving accessibility.
I think people who want to just find the port/package and install it are
more likely to look for "spamassassin the program" than "spamassassin the
perl module collection."
New Stuff since 4.80.1 (ftp://exim.inode.at/exim/ChangeLogs/NewStuff-4.82):
1. New command-line option -bI:sieve will list all supported sieve extensions
of this Exim build on standard output, one per line.
ManageSieve (RFC 5804) providers managing scripts for use by Exim should
query this to establish the correct list to include in the protocol's
SIEVE capability line.
2. If the -n option is combined with the -bP option, then the name of an
emitted option is not output, only the value (if visible to you).
For instance, "exim -n -bP pid_file_path" should just emit a pathname
followed by a newline, and no other text.
3. When built with SUPPORT_TLS and USE_GNUTLS, the SMTP transport driver now
has a "tls_dh_min_bits" option, to set the minimum acceptable number of
bits in the Diffie-Hellman prime offered by a server (in DH ciphersuites)
acceptable for security. (Option accepted but ignored if using OpenSSL).
Defaults to 1024, the old value. May be lowered only to 512, or raised as
far as you like. Raising this may hinder TLS interoperability with other
sites and is not currently recommended. Lowering this will permit you to
establish a TLS session which is not as secure as you might like.
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_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. 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.
5. DSCP support for outbound connections: on a transport using the smtp driver,
set "dscp = ef", for instance, to cause the connections to have the relevant
DSCP (IPv4 TOS or IPv6 TCLASS) value in the header.
Similarly for inbound connections, there is a new control modifier, dscp,
so "warn control = dscp/ef" in the connect ACL, or after authentication.
Supported values depend upon system libraries. "exim -bI:dscp" to list the
ones Exim knows of. You can also set a raw number 0..0x3F.
6. The -G command-line flag is no longer ignored; it is now equivalent to an
ACL setting "control = suppress_local_fixups". The -L command-line flag
is now accepted and forces use of syslog, with the provided tag as the
process name. A few other flags used by Sendmail are now accepted and
ignored.
7. New cutthrough routing feature. Requested by a "control = cutthrough_delivery"
ACL modifier; works for single-recipient mails which are recieved on and
deliverable via SMTP. Using the connection made for a recipient verify,
if requested before the verify, or a new one made for the purpose while
the inbound connection is still active. The bulk of the mail item is copied
direct from the inbound socket to the outbound (as well as the spool file).
When the source notifies the end of data, the data acceptance by the destination
is negociated before the acceptance is sent to the source. If the destination
does not accept the mail item, for example due to content-scanning, the item
is not accepted from the source and therefore there is no need to generate
a bounce mail. This is of benefit when providing a secondary-MX service.
The downside is that delays are under the control of the ultimate destination
system not your own.
The Recieved-by: header on items delivered by cutthrough is generated
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.
New variable families named tls_in_cipher, tls_out_cipher etc. are introduced
for specific access to the information for each connection. The old names
are present for now but deprecated.
Not yet supported: IGNOREQUOTA, SIZE, PIPELINING.
8. New expansion operators ${listnamed:name} to get the content of a named list
and ${listcount:string} to count the items in a list.
9. New global option "gnutls_allow_auto_pkcs11", defaults false. The GnuTLS
rewrite in 4.80 combines with GnuTLS 2.12.0 or later, to autoload PKCS11
modules. For some situations this is desirable, but we expect admin in
those situations to know they want the feature. More commonly, it means
that GUI user modules get loaded and are broken by the setuid Exim being
unable to access files specified in environment variables and passed
through, thus breakage. So we explicitly inhibit the PKCS11 initialisation
unless this new option is set.
Some older OS's with earlier versions of GnuTLS might not have pkcs11 ability,
so have also added a build option which can be used to build Exim with GnuTLS
but without trying to use any kind of PKCS11 support. Uncomment this in the
Local/Makefile:
AVOID_GNUTLS_PKCS11=yes
10. The "acl = name" condition on an ACL now supports optional arguments.
New expansion item "${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.

PP/12 Unbreak server_set_id for NTLM/SPA auth, broken by 4.80 PP/29.
PP/13 Dovecot auth: log better reason to rejectlog if Dovecot did not
advertise SMTP AUTH mechanism to us, instead of a generic
protocol violation error. Also, make Exim more robust to bad
data from the Dovecot auth socket.
TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
When a queue runner is handling a message, Exim first routes the
recipient addresses, during which it prunes them based on the retry
hints database. After that it attempts to deliver the message to
any remaining recipients. It then updates the hints database using
the retry rules.
So if a recipient address works intermittently, it can get repeatedly
deferred at routing time. The retry hints record remains fresh so the
address never reaches the final cutoff time.
This is a fairly common occurrence when a user is bumping up against
their storage quota. Exim had some logic in its local delivery code
to deal with this. However it did not apply to per-recipient defers
in remote deliveries, e.g. over LMTP to a separate IMAP message store.
This change adds a proper retry rule check during routing so that the
final cutoff time is checked against the message's age. We only do
this check if there is an address retry record and there is not a
domain retry record; this implies that previous attempts to handle
the address had the retry_use_local_parts option turned on. We use
this as an approximation for the destination being like a local
delivery, as in LMTP.
I suspect this new check makes the old local delivery cutoff check
redundant, but I have not verified this so I left the code in place.
TF/02 Correct gecos expansion when From: is a prefix of the username.
Test 0254 submits a message to Exim with the header
Resent-From: f
When I ran the test suite under the user fanf2, Exim expanded
the header to contain my full name, whereas it should have added
a Resent-Sender: header. It erroneously treats any prefix of the
username as equal to the username.
This change corrects that bug.
GF/01 DCC debug and logging tidyup
Error conditions log to paniclog rather than rejectlog.
Debug lines prefixed by "DCC: " to remove any ambiguity.
TF/03 Avoid unnecessary rebuilds of lookup-related code.
PP/14 Fix OCSP reinitialisation in SNI handling for Exim/TLS as server.
Bug spotted by Jeremy Harris; was flawed since initial commit.
Would have resulted in OCSP responses post-SNI triggering an Exim
NULL dereference and crash.

SC/01 Update eximstats to watch out for senders sending 'HELO [IpAddr]'
JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
Server implementation by Todd Lyons, client by JH.
Only enabled when compiled with EXPERIMENTAL_PRDR. A new
config variable "prdr_enable" controls whether the server
advertises the facility. If the client requests PRDR a new
acl_data_smtp_prdr ACL is called once for each recipient, after
the body content is received and before the acl_smtp_data ACL.
The client is controlled by bolth of: a hosts_try_prdr option
on the smtp transport, and the server advertisement.
Default client logging of deliveries and rejections involving
PRDR are flagged with the string "PRDR".
PP/16 Fix problems caused by timeouts during quit ACLs trying to double
fclose(). Diagnosis by Todd Lyons.
PP/17 Update configure.default to handle IPv6 localhost better.
Patch by Alain Williams (plus minor tweaks).
Bugzilla 880.
PP/18 OpenSSL made graceful with empty tls_verify_certificates setting.
This is now consistent with GnuTLS, and is now documented: the
previous undocumented portable approach to treating the option as
unset was to force an expansion failure. That still works, and
an empty string is now equivalent.
PP/19 Renamed DNSSEC-enabling option to "dns_dnssec_ok", to make it
clearer that Exim is using the DO (DNSSEC OK) EDNS0 resolver flag,
not performing validation itself.
PP/20 Added force_command boolean option to pipe transport.
Patch from Nick Koston, of cPanel Inc.
JH/15 AUTH support on callouts (and hence cutthrough-deliveries).
Bugzilla 321, 823.
TF/04 Added udpsend ACL modifer and hexquote expansion operator
PP/21 Fix eximon continuous updating with timestamped log-files.
Broken in a format-string cleanup in 4.80, missed when I repaired the
other false fix of the same issue.
Report and fix from Heiko Schlichting.
Bugzilla 1363.
PP/22 Guard LDAP TLS usage against Solaris LDAP variant.
Report from Prashanth Katuri.
PP/23 Support safari_ecdhe_ecdsa_bug for openssl_options.
It's SecureTransport, so affects any MacOS clients which use the
system-integrated TLS libraries, including email clients.
PP/24 Fix segfault from trying to fprintf() to a NULL stdio FILE* if
using a MIME ACL for non-SMTP local injection.

TL/09 Add expansion variable $authenticated_fail_id to keep track of
last id that failed so it may be referenced in subsequent ACL's.
TL/10 Bugzilla 1375 - Prevent TLS rebinding in ldap. Patch provided by
Alexander Miroch.
TL/11 Bugzilla 1382 - Option ldap_require_cert overrides start_tls
ldap library initialization, allowing self-signed CA's to be

TL/13 Bug 1301 - Imported transport SQL logging patch from Axel Rau
renamed to Transport Post Delivery Action by Jeremy Harris, as
EXPERIMENTAL_TPDA.
TL/14 Bugzilla 1217 - Redis lookup support has been added. It is only enabled
when Exim is compiled with EXPERIMENTAL_REDIS. A new config variable
redis_servers = needs to be configured which will be used by the redis

Extracts from the NewStuff,
ftp://exim.inode.at/exim/ChangeLogs/NewStuff-4.80
1. New authenticator driver, "gsasl". Server-only (at present).
This is a SASL interface, licensed under GPL, which can be found at
http://www.gnu.org/software/gsasl/.
This system does not provide sources of data for authentication, so
careful use needs to be made of the conditions in Exim.
2. New authenticator driver, "heimdal_gssapi". Server-only.
A replacement for using cyrus_sasl with Heimdal, now that $KRB5_KTNAME
is no longer honoured for setuid programs by Heimdal. Use the
"server_keytab" option to point to the keytab.
3. The "pkg-config" system can now be used when building Exim to reference
cflags and library information for lookups and authenticators, rather
than having to update "CFLAGS", "AUTH_LIBS", "LOOKUP_INCLUDE" and
"LOOKUP_LIBS" directly. Similarly for handling the TLS library support
without adjusting "TLS_INCLUDE" and "TLS_LIBS".
In addition, setting PCRE_CONFIG=yes will query the pcre-config tool to
find the headers and libraries for PCRE.
4. New expansion variable $tls_bits.
5. New lookup type, "dbmjz". Key is an Exim list, the elements of which will
be joined together with ASCII NUL characters to construct the key to pass
into the DBM library. Can be used with gsasl to access sasldb2 files as
used by Cyrus SASL.
6. OpenSSL now supports TLS1.1 and TLS1.2 with OpenSSL 1.0.1.
Avoid release 1.0.1a if you can. Note that the default value of
"openssl_options" is no longer "+dont_insert_empty_fragments", as that
increased susceptibility to attack. This may still have interoperability
implications for very old clients (see version 4.31 change 37) but
administrators can choose to make the trade-off themselves and restore
compatibility at the cost of session security.
7. Use of the new expansion variable $tls_sni in the main configuration option
tls_certificate will cause Exim to re-expand the option, if the client
sends the TLS Server Name Indication extension, to permit choosing a
different certificate; tls_privatekey will also be re-expanded. You must
still set these options to expand to valid files when $tls_sni is not set.
The SMTP Transport has gained the option tls_sni, which will set a hostname
for outbound TLS sessions, and set $tls_sni too.
A new log_selector, +tls_sni, has been added, to log received SNI values
for Exim as a server.
8. The existing "accept_8bitmime" option now defaults to true. This means
that Exim is deliberately not strictly RFC compliant. We're following
Dan Bernstein's advice in http://cr.yp.to/smtp/8bitmime.html by default.
Those who disagree, or know that they are talking to mail servers that,
even today, are not 8-bit clean, need to turn off this option.
9. Exim can now be started with -bw (with an optional timeout, given as
-bw<timespec>). With this, stdin at startup is a socket that is
already listening for connections. This has a more modern name of
"socket activation", but forcing the activated socket to fd 0. We're
interested in adding more support for modern variants.
10. ${eval } now uses 64-bit values on supporting platforms. A new "G" suffix
for numbers indicates multiplication by 1024^3.
11. The GnuTLS support has been revamped; the three options gnutls_require_kx,
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
SNI support has been added to Exim's GnuTLS integration too.
For sufficiently recent GnuTLS libraries, ${randint:..} will now use
gnutls_rnd(), asking for GNUTLS_RND_NONCE level randomness.
12. With OpenSSL, if built with EXPERIMENTAL_OCSP, a new option tls_ocsp_file
is now available. If the contents of the file are valid, then Exim will
send that back in response to a TLS status request; this is OCSP Stapling.
Exim will not maintain the contents of the file in any way: administrators
are responsible for ensuring that it is up-to-date.
See "experimental-spec.txt" for more details.
13. ${lookup dnsdb{ }} supports now SPF record types. They are handled
identically to TXT record lookups.
14. New expansion variable $tod_epoch_l for higher-precision time.
15. New global option tls_dh_max_bits, defaulting to current value of NSS
hard-coded limit of DH ephemeral bits, to fix interop problems caused by
GnuTLS 2.12 library recommending a bit count higher than NSS supports.
16. tls_dhparam now used by both OpenSSL and GnuTLS, can be path or identifier.
Option can now be a path or an identifier for a standard prime.
If unset, we use the DH prime from section 2.2 of RFC 5114, "ike23".
Set to "historic" to get the old GnuTLS behaviour of auto-generated DH
primes.
17. SSLv2 now disabled by default in OpenSSL. (Never supported by GnuTLS).
Use "openssl_options -no_sslv2" to re-enable support, if your OpenSSL
install was not built with OPENSSL_NO_SSL2 ("no-ssl2").

NULL dereference. Report and patch from Alun Jones.
PP/19 DNS resolver init changes for NetBSD compatibility. (Risk of breakage
on less well tested platforms). Obviates NetBSD pkgsrc patch-ac.
Not seeing resolver debug output on NetBSD, but suspect this is a
resolver implementation change.
PP/20 Revert part of NM/04, it broke log_path containing %D expansions.
Left warnings. Added "eximon gdb" invocation mode.
PP/21 Defaulting "accept_8bitmime" to true, not false.
PP/22 Added -bw for inetd wait mode support.
PP/23 Added PCRE_CONFIG=yes support to Makefile for using pcre-config to
locate the relevant includes and libraries. Made this the default.
PP/24 Fixed headers_only on smtp transports (was not sending trailing dot).
Bugzilla 1246, report and most of solution from Tomasz Kusy.
JH/03 ${eval } now uses 64-bit and supports a "g" suffix (like to "k" and "m").
This may cause build issues on older platforms.
PP/25 Revamped GnuTLS support, passing tls_require_ciphers to
gnutls_priority_init, ignoring Exim options gnutls_require_kx,
gnutls_require_mac & gnutls_require_protocols (no longer supported).
Added SNI support via GnuTLS too.
Made ${randint:..} supplier available, if using not-too-old GnuTLS.
PP/26 Added EXPERIMENTAL_OCSP for OpenSSL.
PP/27 Applied dnsdb SPF support patch from Janne Snabb.
Applied second patch from Janne, implementing suggestion to default
multiple-strings-in-record handling to match SPF spec.
JH/04 Added expansion variable $tod_epoch_l for a higher-precision time.
PP/28 Fix DCC dcc_header content corruption (stack memory referenced,
read-only, out of scope).
Patch from Wolfgang Breyha, report from Stuart Northfield.
PP/29 Fix three issues highlighted by clang analyser static analysis.
Only crash-plausible issue would require the Cambridge-specific
iplookup router and a misconfiguration.
Report from Marcin MirosÅaw.
PP/30 Another attempt to deal with PCRE_PRERELEASE, this one less buggy.
PP/31 %D in printf continues to cause issues (-Wformat=security), so for
now guard some of the printf checks behind WANT_DEEPER_PRINTF_CHECKS.
As part of this, removing so much warning spew let me fix some minor
real issues in debug logging.
PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
assignment on my part. Fixed.
PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
Janne Snabb (who went above and beyond: thank you).
PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
string otherwise requires a connection and a bunch more work and it's
relatively easy to get wrong. Should also expose TLS library linkage
problems.
PP/35 Pull in <features.h> on Linux, for some portability edge-cases of
64-bit ${eval} (JH/03).
PP/36 Define _GNU_SOURCE in exim.h; it's needed for some releases of
GNU libc to support some of the 64-bit stuff, should not lead to
conflicts. Defined before os.h is pulled in, so if a given platform
needs to override this, it can.
PP/37 Unbreak Cyrus SASL auth: SSF retrieval was incorrect, Exim thought
protection layer was required, which is not implemented.
Bugzilla 1254, patch from Wolfgang Breyha.
PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built
into Exim, default to IKE id 23 from RFC 5114 (2048 bit). Make
tls_dhparam take prime identifiers. Also unbreak combination of
OpenSSL+DH_params+TLSSNI.
PP/39 Disable SSLv2 by default in OpenSSL support.
Changes in the port:
- added knob to disable DKIM (requested by alex@ahhyes.net)
- added knob to build with GnuTLS (requested by odhiambo@gmail.com)
- fixed handling of 'twist' directives in hosts.allow

literal name_enable wherever possible, and ${name}_enable
when it's not, to prepare for the demise of set_rcvar().
In cases where I had to hand-edit unusual instances also
modify formatting slightly to be more uniform (and in
some cases, correct). This includes adding some $FreeBSD$
tags, and most importantly moving rcvar= to right after
name= so it's clear that one is derived from the other.
New stuff (from ftp://exim.inode.at/exim/ChangeLogs/NewStuff-4.77):
1. New options for the ratelimit ACL condition: /count= and /unique=.
The /noupdate option has been replaced by a /readonly option.
2. The SMTP transport's protocol option may now be set to "smtps", to
use SSL-on-connect outbound.
3. New variable $av_failed, set true if the AV scanner deferred; ie, when
there is a problem talking to the AV scanner, or the AV scanner running.
4. New expansion conditions, "inlist" and "inlisti", which take simple lists
and check if the search item is a member of the list. This does not
support named lists, but does subject the list part to string expansion.
5. Unless the new EXPAND_LISTMATCH_RHS build option is set when Exim was
built, Exim no longer performs string expansion on the second string of
the match_* expansion conditions: "match_address", "match_domain",
"match_ip" & "match_local_part". Named lists can still be used.
Relevant entries from ChangeLog at
ftp://exim.inode.at/exim/ChangeLogs/ChangeLog-4.77:
TK/01 DKIM Verification: Fix relaxed canon for empty headers w/o
whitespace trailer
TF/02 Fix a couple more cases where we did not log the error message
when unlink() failed. See also change 4.74-TF/03.
TF/03 Make the exiwhat support code safe for signals. Previously
Exim might lock up or crash if it happened to be inside a call
to libc when it got a SIGUSR1 from exiwhat.
The SIGUSR1 handler appends the current process status to the
process log which is later printed by exiwhat. It used to use
the general purpose logging code to do this, but several
functions it calls are not safe for signals.
The new output code in the SIGUSR1 handler is specific to the
process log, and simple enough that it's easy to inspect for
signal safety. Removing some special cases also simplifies the
general logging code. Removing the spurious timestamps from the
process log simplifies exiwhat.

4.76 is the security release that fixes CVE-2011-1764, format string
attack and information leak, both inside the DKIM code.
List of changes (ftp://exim.inode.at/exim/ChangeLogs/ChangeLog-4.76):
PP/01 The new ldap_require_cert option would segfault if used. Fixed.
PP/02 Harmonised TLS library version reporting; only show if
debugging. Layout now matches that introduced for other
libraries in 4.74 PP/03.
PP/03 New openssl_options items: no_sslv2 no_sslv3 no_ticket no_tlsv1
PP/04 New "dns_use_edns0" global option.
PP/05 Don't segfault on misconfiguration of ref:name exim-user as uid.

PP/06 Extra paranoia around buffer usage at the STARTTLS transition.
nb: Exim is not vulnerable to http://www.kb.cert.org/vuls/id/555316
TK/01 Updated PolarSSL code to 0.14.2.
Bugzilla 1097. Patch from Andreas Metzler.
PP/07 Catch divide-by-zero in ${eval:...}.
Fixes bugzilla 1102.
PP/08 Condition negation of bool{}/bool_lax{} did not negate. Fixed.
Bugzilla 1104.
TK/02 Bugzilla 1106: CVE-2011-1764 - DKIM log line was subject to a
format-string attack -- SECURITY: remote arbitrary code execution.
TK/03 SECURITY - DKIM signature header parsing was double-expanded,
second time unintentionally subject to list matching rules,
letting the header cause arbitrary Exim lookups (of items which can
occur in lists, *not* arbitrary string expansion). This allowed for
information disclosure.
PP/09 Fix another SIGFPE (x86) in ${eval:...} expansion, this time related
to INT_MIN/-1 -- value coerced to INT_MAX.
New stuff (ftp://exim.inode.at/exim/ChangeLogs/NewStuff-4.76):
1. The global option "dns_use_edns0" may be set to coerce EDNS0 usage
on or off in the resolver library.
And I am also adding patch for exiqgrep that was taken from
http://bugs.exim.org/show_bug.cgi?id=1103 [1].

Feature-safe: yes
From NewStuff-4.75:
1. In addition to the existing LDAP and LDAP/SSL ("ldaps") support,
there is now LDAP/TLS support, given sufficiently modern OpenLDAP
client libraries. The following global options have been added in
support of this: ldap_ca_cert_dir, ldap_ca_cert_file, ldap_cert_file,
ldap_cert_key, ldap_cipher_suite, ldap_require_cert, ldap_start_tls.
2. The pipe transport now takes a boolean option, "freeze_signal",
default false. When true, if the external delivery command exits on
a signal then Exim will freeze the message in the queue, instead of
generating a bounce.
3. Log filenames may now use %M as an escape, instead of %D (still
available). The %M pattern expands to yyyymm, providing month-level
resolution.
4. The $message_linecount variable is now updated for the maildir_tag
option, in the same way as $message_size, to reflect the real number
of lines, including any header additions or removals from transport.
5. When contacting a pool of SpamAssassin servers configured in
spamd_address, Exim now selects entries randomly, to better scale in
a cluster setup.

Please, note that CVE-2011-0017 is not applicable to FreeBSD,
because setuid() doesn't check RLIMIT_NPROC.
Also fixed the periodic script for tidying the databases: now it won't
produce errors if the lockfile is here, but the actual database file
is gone. [2]
And finally, synced the mirror list to the current one and
pruned old unusable mirrors:
- ftp.csx.cam.ac.uk: not synced anymore;
- www.no.exim.org: no DNS record;
- ftp.demon.nl: no longer mirrors Exim;
- ftp.freenet.de: mirror of ftp.csx.cam.ac.uk;

The changes from the previous release are:
1. TWO SECURITY FIXES: one relating to mail-spools which are
globally writable, the other to locking of MBX folders (not mbox).
These have CVE identifiers CVE-2010-2023 and CVE-2010-2024
2. MySQL stored procedures are now supported.
3. The dkim_domain transport option is now a list, not a single
string, and messages will be signed for each element in the list
(discarding duplicates).
4. The 4.70 release unexpectedly changed the behaviour of dnsdb TXT
lookups in the presence of multiple character strings within
the RR. Prior to 4.70, only the first string would be returned.
The dnsdb lookup now, by default, preserves the pre-4.70
semantics, but also now takes an extended output separator
specification. The separator can be followed by a semicolon, to
concatenate the individual text strings together with no join
character, or by a comma and a second separator character, in
which case the text strings within a TXT record are joined on
that second character. Administrators are reminded that DNS
provides no ordering guarantees between multiple records in an
RRset. For example:
foo.example. IN TXT "a" "b" "c"
foo.example. IN TXT "d" "e" "f"
${lookup dnsdb{>/ txt=foo.example}} -> "a/d"
${lookup dnsdb{>/; txt=foo.example}} -> "def/abc"
${lookup dnsdb{>/,+ txt=foo.example}} -> "a+b+c/d+e+f"
