Add missing curly brackets that caused res_ninit() to be called
with non-zeroed state structure. In NetBSD, res_ninit() detects
the mistake and quickly calls res_ndestroy(), which will close file
descriptors based on the random data provided in the state structure.
The result at mine is sendmail going mute after the MAIL FROM
command.
Fix spurious (may be forged) logs when receiving via IPv6 socket,
and fix sending to IPv6-enabled relay.
Bump PKGREVISION
(no revision bump for libmilter, it's not affected)
to determine whether to use the blacklistd feature. This allows
for automatically picking up new OSes that provide blacklistd as
well as ignoring older versions of NetBSD and FreeBSD that don't
have blacklistd.
Add UseBlacklist to M4 config generator. This means that you can
turn it on by doing something like:
LOCAL_CONFIG
...
define(`confUSE_BLACKLIST', `True')dnl
...
It is set to false as the feature is experimental having just been
created.
Ride previous PKGREVISION bump as it was less than an hour ago.
originally created for FreeBSD and were ported to pkgsrc by Hauke
Fath with some cleanup by myself.
These patches add a new "UseBlacklist" option to sendmail to have
it send authentication failure notices to blacklistd.
sendmail options BadRcptShutdown and BadRcptShutdownGood to be
used. "ffr" stands for For Future Release, which means it is a
beta test feature that may show up in a future release of sendmail.
The sendmail-ffr-badrcptshutdown option is disabled by default so
no change to binary packages, thus not bumping PKGREVISION.
MASTER_SITES= site1 \
site2
style continuation lines to be simple repeated
MASTER_SITES+= site1
MASTER_SITES+= site2
lines. As previewed on tech-pkg. With thanks to rillig for fixing pkglint
accordingly.
This will create two sendmail service instances, :mta and :msp, to start
the two sendmail instances that are usually required. The :mta instance
optionally depends on spamassassin and spamass-milter.
pkgsrc change: default to enable TLS
- this has been requested a couple of times and most systems are going
to have a recent enough version of openssl so in most cases there
won't be additional dependencies
8.15.2/8.15.2 2015/07/03
If FEATURE(`nopercenthack') is used then some bogus input triggered
a recursion which was caught and logged as
SYSERR: rewrite: excessive recursion (max 50) ...
Fix based on patch from Ondrej Holas.
DHParameters now by default uses an included 2048 bit prime.
The value 'none' previously caused a log entry claiming
there was an error "cannot read or set DH parameters".
Also note that this option applies to the server side only.
The U= mailer field didn't accept group names containing hyphens,
underbars, or periods. Based on patch from David Gwynne
of the University of Queensland.
CONFIG: Allow connections from IPv6:0:0:0:0:0:0:0:1 to relay again.
Patch from Lars-Johan Liman of Netnod Internet Exchange.
CONFIG: New option UseCompressedIPv6Addresses to select between
compressed and uncompressed IPv6 addresses. The default
value depends on the compile-time option IPV6_FULL:
For 1 the default is False, for 0 it is True, thus
preserving the current behaviour. Based on patch from
John Beck of Oracle.
CONFIG: Account for IPv6 localhost addresses in
FEATURE(`block_bad_helo'). Suggested by Andrey Chernov
from FreeBSD and Robert Scheck from the Fedora Project.
CONFIG: Account for IPv6 localhost addresses in check_mail ruleset.
LIBMILTER: Deal with more invalid protocol data to avoid potential
crashes. Problem noted by Dimitri Kirchner.
LIBMILTER: Allow a milter to specify an empty macro list ("", not
NULL) in smfi_setsymlist() so no macro is sent for the
selected stage.
MAKEMAP: A change to check TrustedUser in fewer cases which was
made in 2013 caused a potential regression when makemap
was run as root (which should not be done anyway).
Note: sendmail often contains options "For Future Releases"
(prefix _FFR_) which might be enabled in a subsequent
version or might simply be removed as they turned out not
to be really useful. These features are usually not
documented but if they are, then the required (FFR)
options are listed in
- doc/op/op.* for rulesets and macros,
- cf/README for mc/cf options.
Note that there was an incompatible config change for IPv6 users.
See the MESSAGE file for details.
pkgsrc change: delete a couple of patches that have been upstreamed
Proofpoint, Inc., and the Sendmail Consortium announce the availability
of sendmail 8.15.1. This release:
o offers more TLS related features,
o does not ignore temporary map lookup failures during header rewriting,
o uses uncompressed IPv6 addresses by default, which is an incompatible
change that requires to update IPv6 related configuration data.
as well as many other enhancements. For details see the release
notes below.
SENDMAIL RELEASE NOTES
This listing shows the version of the sendmail binary, the version
of the sendmail configuration files, the date of release, and a
summary of the changes in that release.
8.15.1/8.15.1 2014/12/06
SECURITY: Properly set the close-on-exec flag for file descriptors
(except stdin, stdout, and stderr) before executing mailers.
If header rewriting fails due to a temporary map lookup failure,
queue the mail for later retry instead of sending it
without rewriting the header. Note: this is done
while the mail is being sent and hence the transaction
is aborted, which only works for SMTP/LMTP mailers
hence the handling of temporary map failures is
suppressed for other mailers. SMTP/LMTP servers may
complain about aborted transactions when this problem
occurs.
See also "DNS Lookups" in sendmail/TUNING.
Incompatible Change: Use uncompressed IPv6 addresses by default,
i.e., they will not contain "::". For example,
instead of ::1 it will be 0:0:0:0:0:0:0:1. This
permits a zero subnet to have a more specific match,
such as different map entries for IPv6:0:0 vs IPv6:0.
This change requires that configuration data
(including maps, files, classes, custom ruleset,
etc) must use the same format, so make certain such
configuration data is updated before using 8.15.
As a very simple check search for patterns like
'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. If necessary,
the prior format can be retained by compiling with:
APPENDDEF(`conf_sendmail_ENVDEF', `-DIPV6_FULL=0')
in your devtools/Site/site.config.m4 file.
If debugging is turned on (-d0.14) also print the OpenSSL
versions, both build time and run time
(provided STARTTLS is compiled in).
If a connection to the MTA is dropped by the client before its
hostname can be validated, treat it as "may be forged",
so that the unvalidated hostname is not passed to a
milter in xxfi_connect().
Add a timeout for communication with socket map servers
which can be specified using the -d option.
Add a compile time option HESIOD_ALLOW_NUMERIC_LOGIN to allow
numeric logins even if HESIOD is enabled.
The new option CertFingerprintAlgorithm specifies the finger-
print algorithm (digest) to use for the presented cert.
If the option is not set, md5 is used and the macro
{cert_md5} contains the cert fingerprint.
However, if the option is set, the specified algorithm
(e.g., sha1) is used and the macro {cert_fp} contains
the cert fingerprint.
That is, as long as the option is not set, the behaviour
does not change, but otherwise, {cert_md5} is superseded
by {cert_fp} even if you set CertFingerprintAlgorithm
to md5.
The options ServerSSLOptions and ClientSSLOptions can be used
to set SSL options for the server and client side
respectively. See SSL_CTX_set_options(3) for a list.
Note: this change turns on SSL_OP_NO_SSLv2 and
SSL_OP_NO_TICKET for the client. See doc/op/op.me
for details.
A new map type "arpa" is available to reverse an IP (IPv4 or IPv6)
address. It returns the string for the PTR lookup, but
without trailing {ip6,in-addr}.arpa.
New operation mode 'C' just checks the configuration file, e.g.,
sendmail -C new.cf -bC
will perform a basic syntax/consistency check of new.cf.
The mailer flag 'I' is deprecated and will be removed in a
future version.
Allow local (not just TCP) socket connections to the server, e.g.,
O DaemonPortOptions=Family=local, Addr=/var/mta/server.sock
can be used.
If the new option MaxQueueAge is set to a value greater than zero,
entries in the queue will be retried during a queue run
only if the individual retry time has been reached which
is doubled for each attempt. The maximum retry time is
limited by the specified value.
New DontBlameSendmail option GroupReadableDefaultAuthInfoFile
to relax requirement for DefaultAuthInfo file.
Reset timeout after receiving a message to appropriate value if
STARTTLS is in use. Based on patch by Kelsey Cummings
of Sonic.net.
Report correct error messages from the LDAP library for a range of
small negative return values covering those used by OpenLDAP.
Fix compilation with Berkeley DB 5.0 and 6.0. Patch from
Allan E Johannesen of Worcester Polytechnic Institute.
CONFIG: FEATURE(`nopercenthack') takes one parameter: reject or
nospecial which describes whether to disallow "%" in the
local part of an address.
DEVTOOLS: Fix regression in auto-detection of libraries when only
shared libraries are available. Problem reported by
Bryan Costales.
LIBMILTER: Mark communication socket as close-on-exec in case
a user's filter starts other applications.
Based on patch from Paul Howarth.
Portability:
SunOS 5.12 has changed the API for sigwait(2) to conform
with XPG7. Based on patch from Roger Faulkner of Oracle.

8.14.9/8.14.9 2014/05/21
SECURITY: Properly set the close-on-exec flag for file descriptors
(except stdin, stdout, and stderr) before executing mailers.
Fix a misformed comment in conf.c: "/*" within comment
which may cause a compilation error on some systems.
Problem reported by John Beck of Oracle.
DEVTOOLS: Fix regression in auto-detection of libraries when only
shared libraries are available. Problem reported by
Bryan Costales.
minor feature additions.
8.14.8/8.14.8 2014/01/26
Properly initialize all OpenSSL algorithms for versions before
OpenSSL 0.9.8o. Without this SHA2 algorithms may not
work properly, causing for example failures for certs
that use sha256WithRSAEncryption as signature algorithm.
When looking up hostnames, ensure only to return those records
for the requested family (AF_INET or AF_INET6).
On system that have NEEDSGETIPNODE and NETINET6
this may have failed and cause delivery problems.
Problem noted by Kees Cook.
A new mailer flag '!' is available to suppress an MH hack
that drops an explicit From: header if it is the
same as what sendmail would generate.
Add an FFR (for future release) to use uncompressed IPv6 addresses,
i.e., they will not contain "::". For example, instead
of ::1 it will be 0:0:0:0:0:0:0:1. This means that
configuration data (including maps, files, classes,
custom ruleset, etc) have to use the same format.
This will be turned on in 8.15. It can be enabled in 8.14
by compiling with:
APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_IPV6_FULL')
in your devtools/Site/site.config.m4 file.
Add an additional case for the WorkAroundBrokenAAAA check when
dealing with broken nameservers by ignoring SERVFAIL
errors returned on T_AAAA (IPv6) lookups at delivery time.
Problem noted by Pavel Timofeev of OCS.
If available, pass LOGIN_SETCPUMASK and LOGIN_SETLOGINCLASS to
setusercontext() on deliveries as a different user.
Patch from Edward Tomasz Napierala from FreeBSD.
Avoid compiler warnings from a change in Cyrus-SASL 2.1.25.
Patch from Hajimu UMEMOTO from FreeBSD.
Add support for DHParameters 2048-bit primes.
CONFIG: Accept IPv6 literals when evaluating the HELO/EHLO argument
in FEATURE(`block_bad_helo'). Suggested by Andrey Chernov.
LIBSMDB: Add a missing check for malloc() in libsmdb/smndbm.c.
Patch from Bill Parker.
LIBSMDB: Fix minor memory leaks in libsmdb/ if allocations
fail. Patch from John Beck of Oracle.
Portability:
Add support for Darwin 12.x and 13.x (Mac OS X 10.8 and 10.9).
On Linux use socklen_t as the type for the 3rd argument
for getsockname/getpeername if the glibc version is at
least 2.1.

8.14.7/8.14.7 2013/04/21
Drop support for IPv4-mapped IPv6 addresses to prevent the MTA
from using a mapped address over a legitimate IPv6 address
and to enforce the proper semantics over the IPv6
connection. Problem noted by Ulrich Sporlein.
Fix a regression introduced in 8.14.6: the wrong list of
macros was sent to a milter in the EHLO stage.
Problem found by Fabrice Bellet, reported via RedHat
(Jaroslav Skarvada).
Fix handling of ORCPT parameter for DSNs: xtext decoding
was not performed and a wrong syntax check was applied
to the "addr-type" field. Problem noted by Dan Lukes
of Obludarium.
Fix handling of NUL characters in the MIME conversion functions
so that message bodies containing them will be sent
on properly. Note: this usually also affects mails
that are not converted as those functions are used
for other purposes too. Problem noted by Elchonon
Edelson of Lockheed Martin.
Do not perform "duplicate" elimination of recipients if they
resolve to the error mailer using a temporary failure
(4xy) via ruleset 0. Problem noted by Akira Takahashi
of IIJ.
CONTRIB: Updated version of etrn.pl script from John Beck
of Oracle.
Portability:
Unlike gcc, clang doesn't apply full prototypes to K&R
definitions.
- will look at making recently requested changes in a subsequent commit
8.14.6/8.14.6 2012/12/23
Fix a regression introduced in 8.14.5: if a server offers
two AUTH lines, the MTA would not read them after
STARTTLS has been used and hence SMTP AUTH for
the client side would fail. Problem noted by Lena.
Do not cache hostnames internally in a non case sensitive way
as that may cause addresses to change from lower case
to upper case or vice versa. These header modifications
can cause problems with milters that rely on receiving
headers in the same way as they are being sent out such
as a DKIM signing milter.
If MaxQueueChildren is set then it was possible that new queue
runners could not be started anymore because an
internal counter was subject to a race condition.
If a milter decreases the timeout it waits for a communication
with the MTA, the MTA might experience a write() timeout.
In some situations, the resulting error might have been
ignored. Problem noted by Werner Wiethege.
Note: decreasing the communication timeout in a milter
should not be done without considering the potential
problems.
smfi_setsymlist() now properly sets the list of macros for
the milter which invoked it, instead of a global
list for all milters. Problem reported by
David Shrimpton of the University of Queensland.
If Timeout.resolver.retrans is set to a value larger than 20,
then resolver.retry was temporarily set to 0 for
gethostbyaddr() lookups. Now it is set to 1 instead.
Patch from Peter.
If sendmail could not lock the statistics file due to a system
error, and sendmail later sends a DSN for a mail that
triggered such an error, then sendmail tried to access
memory that was freed before (causing a crash on some
systems). Problem reported by Ryan Stone.
Do not log negative values for size= nor pri= to avoid confusing
log parsers, instead limit the values to LONG_MAX.
Account for an API change in newer versions of Cyrus-SASL.
Patch from Hajimu UMEMOTO from FreeBSD.
Do not try to resolve link-local addresses for IPv4 (just as it
is done for IPv6). Patch from John Beck of Oracle.
Improve logging of client and server STARTTLS connection failures
that may be due to incompatible cipher lists by including
the reason for the failure in a single log line. Suggested
by James Carey of Boeing.
Portability:
Add support for Darwin 11.x and 12.x (Mac OS X 10.7 and 10.8).
Add support for SunOS 5.12 (aka Solaris 12). Patch from
John Beck of Oracle.
8.14.5/8.14.5 2011/05/17
Do not cache SMTP extensions across connections as the cache
is based on hostname which may not be a unique identifier
for a server, i.e., different machines may have the
same hostname but provide different SMTP extensions.
Problem noted by Jim Hermann.
Avoid an out-of-bounds access in case a resolver reply for a DNS
map lookup returns a size larger than 1K. Based on a
patch from Dr. Werner Fink of SuSE.
If a job is aborted using the interrupt signal (e.g., control-C from
the keyboard), perform minimal cleanup to avoid invoking
functions that are not signal-safe. Note: in previous
versions the mail might have been queued up already
and would be delivered subsequently, now an interrupt
will always remove the queue files and thus prevent
delivery.
Per RFC 6176, when operating as a TLS client, do not offer SSLv2.
Since TLS session resumption is never used as a client, disable
use of RFC 4507-style session tickets.
Work around gcc4 versions which reverse 25 years of history and
no longer align char buffers on the stack, breaking calls
to resolver functions on strict alignment platforms.
Found by Stuart Henderson of OpenBSD.
Read at most two AUTH lines from a server greeting (up to two
lines are read because servers may use "AUTH mechs" and
"AUTH=mechs"). Otherwise a malicious server may exhaust
the memory of the client. Bug report by Nils of MWR
InfoSecurity.
Avoid triggering an assertion in the OpenLDAP code when the
connection to an LDAP server is lost while making a query.
Problem noted and patch provided by Andy Fiddaman.
If ConnectOnlyTo is set and sendmail is compiled with NETINET6
it would try to use an IPv6 address if an IPv4 (or
unparseable) address is specified.
If SASLv2 is used, make sure that the macro {auth_authen} is
stored in xtext format to avoid problems with parsing
it. Problem noted by Christophe Wolfhugel.
CONFIG: FEATURE(`ldap_routing') in 8.14.4 tried to add a missing
-T<TMPF> that is required, but failed for some cases
that did not use LDAP. This change has been undone
until a better solution can be implemented. Problem
found by Andy Fiddaman.
CONFIG: Add cf/ostype/solaris11.m4 for Solaris11 support.
Contributed by Casper Dik of Oracle.
CONTRIB: qtool.pl: Deal with H entries that do not have a
letter between the question marks. Patch from
Stefan Christensen.
DOC: Use a better description for the -i option in sendmail.
