OK.. I know a lot of you are running Sendmail, so.. ;) --- Begin Message --------BEGIN PGP SIGNED MESSAGE----- Sendmail, Inc. and the Sendmail Consortium are proud to announce the release of sendmail 8.11.0. Due to the easing of crypto export regulations in the United States, we have able to include the STARTTLS and SMTP Authentication Security Layer code in the open source version. Beyond the new encryption features and associated options, there are a number of bug fixes in this release including: * Overly restrictive gid security checking in 8.10.2 was relaxed. * DaemonPortOptions Family= defaults to inet if not specified. IPv6 users will have to add an additional DaemonPortOptions settings with Family=inet6. * LDAP map fixes * mail.local Content-Length header fix See the RELEASE_NOTES for complete details and other changes. The release is available from: ftp://ftp.sendmail.org/pub/sendmail/sendmail.8.11.0.tar.gz ftp://ftp.sendmail.org/pub/sendmail/sendmail.8.11.0.tar.Z ftp://ftp.sendmail.org/pub/sendmail/sendmail.8.11.0.tar.sig with MD5 signatures: 5a51738a4f78f110f6b0b2f1ed38aea8 sendmail.8.11.0.tar.Z 95a21f6838dc0489924ca71d98e40edf sendmail.8.11.0.tar.gz 2e8bda5d2060770d39bc04e485862b09 sendmail.8.11.0.tar.sig You only need one of the first two files (either the gzip'ed version or the compressed version). The .sig file is a PGP signatures of the tar file (after uncompressing it). It is signed with the Sendmail Signing Key/2000, available on the web site (http://www.sendmail.org/) or on the public key servers. Since sendmail 8.11 and later includes hooks to cryptography, the following information from OpenSSL applies to sendmail as well. PLEASE REMEMBER THAT EXPORT/IMPORT AND/OR USE OF STRONG CRYPTOGRAPHY SOFTWARE, PROVIDING CRYPTOGRAPHY HOOKS OR EVEN JUST COMMUNICATING TECHNICAL DETAILS ABOUT CRYPTOGRAPHY SOFTWARE IS ILLEGAL IN SOME PARTS OF THE WORLD. SO, WHEN YOU IMPORT THIS PACKAGE TO YOUR COUNTRY, RE-DISTRIBUTE IT FROM THERE OR EVEN JUST EMAIL TECHNICAL SUGGESTIONS OR EVEN SOURCE PATCHES TO THE AUTHOR OR OTHER PEOPLE YOU ARE STRONGLY ADVISED TO PAY CLOSE ATTENTION TO ANY EXPORT/IMPORT AND/OR USE LAWS WHICH APPLY TO YOU. THE AUTHORS ARE NOT LIABLE FOR ANY VIOLATIONS YOU MAKE HERE. SO BE CAREFUL, IT IS YOUR RESPONSIBILITY. 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 [email protected] 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. CONFIG: Catch invalid addresses containing a ',' at the wrong place. Patch from Neil Rickert of Northern Illinois University. CONFIG: New variables for the new sendmail options: confCACERT_PATH CACERTPath confCACERT CACERTFile confCLIENT_CERT ClientCertFile confCLIENT_KEY ClientKeyFile confDH_PARAMETERS DHParameters confRAND_FILE RandFile confSERVER_CERT ServerCertFile confSERVER_KEY ServerKeyFile CONFIG: Provide basic rulesets for TLS policy control and add new tags to the access database to support these policies. See cf/README for more information. CONFIG: Add TLS information to the Received: header. CONFIG: Call tls_client ruleset from check_mail in case it wasn't called due to a STARTTLS command. CONFIG: If TLS_PERM_ERR is defined, TLS related errors are permanent instead of temporary. CONFIG: FEATURE(`relay_hosts_only') didn't work in combination with the access map and relaying to a domain without using a To: tag. Problem noted by Mark G. Thomas of Mark G. Thomas 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. CONTRIB: Add link_hash.sh to create symbolic links to the hash of X.509 certificates. CONTRIB: passwd-to-alias.pl: More protection from special characters; treat special shells as root aliases; skip entries where the GECOS full name and username match. From Ulrich Windl of the Universitat Regensburg. CONTRIB: qtool.pl: Add missing last_modified_time method and fix a typo. Patch from Graeme Hewson of Oracle. CONTRIB: re-mqueue.pl: Improve handling of a race between re-mqueue and sendmail. Patch from Graeme Hewson of Oracle. CONTRIB: re-mqueue.pl: Don't exit(0) at end so can be called as subroutine Patch from Graeme Hewson of Oracle. CONTRIB: Add movemail.pl (move old mail messages between queues by calling re-mqueue.pl) and movemail.conf (configuration script for movemail.pl). From Graeme Hewson of Oracle. CONTRIB: Add cidrexpand (expands CIDR blocks as a preprocessor to makemap). From Derek J. Balling of Yahoo,Inc. DEVTOOLS: INSTALL_RAWMAN installation option mistakenly applied any extension modifications (e.g., MAN8EXT) to the installation target. Patch from James Ralston of Carnegie Mellon University. DEVTOOLS: Add support for SunOS 5.9. DEVTOOLS: New option confLN contains the command used to create links. LIBSMDB: Berkeley DB 2.X and 3.X errors might be lost and not reported. MAIL.LOCAL: DG/UX portability. Problem noted by Tim Boyer of Denman Tire Corporation. MAIL.LOCAL: Prevent a possible DoS attack when compiled with -DCONTENTLENGTH. Based on patch from [email protected] MAILSTATS: Fix usage statement (-p and -o are optional). MAKEMAP: Change man page layout as workaround for problem with nroff and -man on Solaris 7. Patch from Larry Williamson. RMAIL: AIX 4.3 has snprintf(). Problem noted by David Hayes of Black Diamond Equipment, Limited. RMAIL: Prevent a segmentation fault if the incoming message does not have a From line. VACATION: Read all of the headers before deciding whether or not to respond instead of stopping after finding recipient.
