TODO: STARTTLS support
--- 8.10.2 -> 8.11.0
8.11.0/8.11.0 2000/07/19
SECURITY: If sendmail is installed as a non-root set-user-ID binary
(not the normal case), some operating systems will still
keep a saved-uid of the effective-uid when sendmail tries
to drop all of its privileges. If sendmail needs to drop
these privileges and the operating system doesn't set the
saved-uid as well, exit with an error. Problem noted by
Kari Hurtta of the Finnish Meteorological Institute.
SECURITY: sendmail depends on snprintf() NUL terminating the string
it populates. It is possible that some broken
implementations of snprintf() exist that do not do this.
Systems in this category should compile with
-DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your
system and report broken implementations to
sendmail-bugs@sendmail.org and your OS vendor. Problem
noted by Slawomir Piotrowski of TELSAT GP.
Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS).
Implementation influenced by the example programs of
OpenSSL and the work of Lutz Jaenicke of TU Cottbus.
Add new STARTTLS related options CACERTPath, CACERTFile,
ClientCertFile, ClientKeyFile, DHParameters, RandFile,
ServerCertFile, and ServerKeyFile. These are documented in
cf/README and doc/op/op.*.
New STARTTLS related macros: ${cert_issuer}, ${cert_subject},
${tls_version}, ${cipher}, ${cipher_bits}, ${verify},
${server_name}, and ${server_addr}. These are documented
in cf/README and doc/op/op.*.
Add support for the Entropy Gathering Daemon (EGD) for better
random data.
New DontBlameSendmail option InsufficientEntropy for systems which
don't properly seed the PRNG for OpenSSL but want to
try to use STARTTLS despite the security problems.
Support the security layer in SMTP AUTH for mechanisms which
support encryption. Based on code contributed by Tim
Martin of CMU.
Add new macro ${auth_ssf} to reflect the SMTP AUTH security
strength factor.
LDAP's -1 (single match only) flag was not honored if the -z
(delimiter) flag was not given. Problem noted by ST Wong of
the Chinese University of Hong Kong. Fix from Mark Adamson
of CMU.
Add more protection from accidentally tripping OpenLDAP 1.X's
ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute().
Suggested by Kurt Zeilenga of OpenLDAP.
Fix the default family selection for DaemonPortOptions. As
documented, unless a family is specified in a
DaemonPortOptions option, "inet" is the default. It is
also the default if no DaemonPortOptions value is set.
Therefore, IPv6 users should configure additional sockets
by adding DaemonPortOptions settings with Family=inet6 if
they wish to also listen on IPv6 interfaces. Problem noted
by Jun-ichiro itojun Hagino of the KAME Project.
Set ${if_family} when setting ${if_addr} and ${if_name} to reflect
the interface information for an outgoing connection.
Not doing so was creating a mismatch between the socket
family and address used in subsequent connections if the
M=b modifier was set in DaemonPortOptions. Problem noted
by John Beck of Sun Microsystems.
If DaemonPortOptions modifier M=b is used, determine the socket
family based on the IP address. ${if_family} is no longer
persistent (i.e., saved in qf files). Patch from John Beck
of Sun Microsystems.
sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family}
macros for both the incoming interface address/family and
the outgoing interface address/family. In order for M=b
modifier in DaemonPortOptions to work properly, preserve
the incoming information in the queue file for later
delivery attempts.
Use SMTP error code and enhanced status code from check_relay in
responses to commands. Problem noted by Jeff Wasilko of
smoe.org.
Add more vigilance in checking for putc() errors on output streams
to protect from a bug in Solaris 2.6's putc(). Problem
noted by Graeme Hewson of Oracle.
The LDAP map -n option (return attribute names only) wasn't working.
Problem noted by Ajay Matia.
Under certain circumstances, an address could be listed as deferred
but would be bounced back to the sender as failed to be
delivered when it really should have been queued. Problem
noted by Allan E Johannesen of Worcester Polytechnic Institute.
Prevent a segmentation fault in a child SMTP process from getting
the SMTP transaction out of sync. Problem noted by Per
Hedeland of Ericsson.
Turn off RES_DEBUG if SFIO is defined unless SFIO_STDIO_COMPAT
is defined to avoid a core dump due to incompatibilities
between sfio and stdio. Problem noted by Neil Rickert
of Northern Illinois University.
Don't log useless envelope ID on initial connection log. Problem
noted by Kari Hurtta of the Finnish Meteorological Institute.
Convert the free disk space shown in a control socket status query
to kilobyte units.
If TryNullMXList is True and there is a temporary DNS failure
looking up the hostname, requeue the message for a later
attempt. Problem noted by Ari Heikkinen of Pohjois-Savo
Polytechnic.
Under the proper circumstances, failed connections would be recorded
as "Bad file number" instead of "Connection failed" in the
queue file and persistent host status. Problem noted by
Graeme Hewson of Oracle.
Avoid getting into an endless loop if a non-hoststat directory exists
within the hoststatus directory (e.g., lost+found).
Patch from Valdis Kletnieks of Virginia Tech.
Make sure Timeout.queuereturn=now returns a bounce message to the
sender. Problem noted by Per Hedeland of Ericsson.
If a message data file can't be opened at delivery time, panic and
abort the attempt instead of delivering a message that
states "<<< No Message Collected >>>".
Fixup the GID checking code from 8.10.2 as it was overly
restrictive. Problem noted by Mark G. Thomas of Mark
G. Thomas Consulting.
Preserve source port number instead of replacing it with the ident
port number (113).
Document the queue status characters in the mailq man page.
Suggested by Ulrich Windl of the Universitat Regensburg.
Process queued items in which none of the recipient addresses have
host portions (or there are no recipients). Problem noted
by Valdis Kletnieks of Virginia Tech.
If a cached LDAP connection is used for multiple maps, make sure
only the first to open the connection is allowed to close
it so a later map close doesn't break the connection for
other maps. Problem noted by Wolfgang Hottgenroth of UUNET.
Netscape's LDAP libraries do not support Kerberos V4
authentication. Patch from Rainer Schoepf of the
University of Mainz.
Provide workaround for inconsistent handling of data passed
via callbacks to Cyrus SASL prior to version 1.5.23.
Mention ENHANCEDSTATUSCODES in the SMTP HELP helpfile. Omission
noted by Ulrich Windl of the Universitat Regensburg.
Portability:
Add the ability to read IPv6 interface addresses into class
'w' under FreeBSD (and possibly others). From Jun
Kuriyama of IMG SRC, Inc. and the FreeBSD Project.
Replace code for finding the number of CPUs on HPUX.
NCRUNIX MP-RAS 3.02 SO_REUSEADDR socket option does not
work properly causing problems if the accept()
fails and the socket needs to be reopened. Patch
from Tom Moore of NCR.
NetBSD uses a .0 extension of formatted man pages. From
Andrew Brown of Graffiti World Wide, Inc.
Return to using the IPv6 AI_DEFAULT flag instead of AI_V4MAPPED
for calls to getipnodebyname(). The Linux
implementation is broken so AI_ADDRCONFIG is stripped
under Linux. From John Beck of Sun Microsystems and
John Kennedy of Cal State University, Chico.

Consulting.
CONFIG: Set confEBINDIR to /usr/sbin to match the devtools entry in
OSTYPE(`linux') and OSTYPE(`mklinux'). From Tim Pierce of
RootsWeb.com.
CONFIG: Make sure FEATURE(`nullclient') doesn't use aliasing and
forwarding to make it as close to the old behavior as
possible. Problem noted by George W. Baltz of the
University of Maryland.
CONFIG: Added OSTYPE(`darwin') for Mac OS X and Darwin users. From
Wilfredo Sanchez of Apple Computer, Inc.
CONFIG: Changed the map names used by FEATURE(`ldap_routing') from
ldap_mailhost and ldap_mailroutingaddress to ldapmh and
ldapmra as underscores in map names cause problems if
underscore is in OperatorChars. Problem noted by Bob Zeitz
of the University of Alberta.
CONFIG: Apply blacklist_recipients also to hosts in class {w}.
Patch from Michael Tratz of Esosoft Corporation.
CONFIG: Use A=TCP ... instead of A=IPC ... in SMTP mailers.
