sendmail 8.12.6 available

-----BEGIN PGP SIGNED MESSAGE-----

Sendmail, Inc., and the Sendmail Consortium announce the availability
of sendmail 8.12.6.  Several mostly minor problems have been fixed,
e.g., queue selection in case of invalid recipients might have been
wrong, a combination of FallbackMXhost and relay_based_on_MX would
result in an open relay, owner- envelope splitting was broken if
SuperSafe was set to interactive, base64 encoded client authentication
data for SMTP AUTH may not work, and the treatment of $#discard for
recipients might have been inconsistent.  Compared to 8.12.6.Beta1
only some spelling errors have been fixed.

For a complete list of changes see the release notes down below.

Please send bug reports to [email protected] as usual.

You only need one of the first two files (either the gzip'ed version or the
compressed version).  The .sig file contains the PGP signature of the tar
file (after uncompressing it).  The PGP signature was created using the
Sendmail Signing Key/2002, available on the web site
(http://www.sendmail.org/) or on the public key servers.

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.

8.12.6/8.12.6	2002/08/26
	Do not add the FallbackMXhost (or its MX records) to the list
		returned by the bestmx map when -z is used as option.
		Otherwise sendmail may act as an open relay if FallbackMXhost
		and FEATURE(`relay_based_on_MX') are used together.
		Problem noted by Alexander Ignatyev.
	Properly split owner- mailing list messages when SuperSafe is set
		to interactive.  Problem noted by Todd C. Miller of
		Courtesan Consulting.
	Make sure that an envelope is queued in the selected queue group
		even if some recipients are deleted or invalid.  Problem
		found by Chris Adams of HiWAAY Informations Services.
	Do not send a bounce message if a message is completely collected
		from the SMTP client.  Problem noted by Kari Hurtta of the
		Finnish Meteorological Institute.
	Provide an 'install-submit-st' target for sendmail/Makefile to
		install the MSP statistics file using the file named in the
		confMSP_STFILE devtools variable.  Requested by Jeff
		Earickson of Colby College.
	Queue up mail with a temporary error if setusercontext() fails
		during a delivery attempt.  Patch from Todd C. Miller of
		Courtesan Consulting.
	Fix handling of base64 encoded client authentication data for
		SMTP AUTH.  Patch from Elena Slobodnik of life medien GmbH.
	Set the OpenLDAP option LDAP_OPT_RESTART so the client libraries
		restart interrupted system calls.  Problem noted by Luiz
		Henrique Duma of BSIOne.
	Prevent a segmentation fault if a program passed a NULL envp using
		execve().
	Document a problem with the counting of queue runners that may
		cause delays if MaxQueueChildren is set too low. Problem
		noted by Ian Duplisse of Cable Television Laboratories, Inc.
	If discarding a message based on a recipient, don't try to look up
		the recipient in the mailbox database if F=w is set.  This
		allows users to discard bogus recipients when dealing with
		spammers without tipping them off.  Problem noted by Neil
		Rickert of Northern Illinois University.
	If applying a header check to a header with unstructured data,
		e.g., Subject:, then do not run syntax checks that are
		supposed for addresses on the header content.
	Count messages rejected/discarded via the check_data ruleset.
	Portability:
		Fix compilation on systems which do not allow simple
			copying of the variable argument va_list.  Based on
			fix from Scott Walters.
		Fix NSD map open bug.  From Michel Bourget of SGI.
		Add some additional IRIX shells to the default shell
			list.  From Michel Bourget of SGI.
		Fix compilation issues on Mac OS X 10.2 (Darwin 6.0).
			NETISO support has been dropped.
	CONFIG: There was a seemingly minor change in 8.12.4 with respect
		to handling entries of IP nets/addresses with RHS REJECT.
		These would be rejected in check_rcpt instead of only
		being activated in check_relay.  This change has been made to
		avoid potential bogus temporary rejection of relay attempts
		"450 4.7.1 Relaying temporarily denied. Cannot resolve PTR
		record for ..." if delay_checks is enabled.  However, this
		modification causes a change of behavior if an IP net/address
		is listed in the access map with REJECT and a host/domain
		name is listed with OK or RELAY, hence it has been reversed
		such that the behavior of 8.12.3 is restored.  The original
		change was made on request of Neil Rickert of Northern
		Illinois University, the side effect has been found by
		Stefaan Van Hoornick.
	CONFIG: Make sure delay_checks works even for sender addresses
		using the local hostname ($j) or domains in class {P}.
		Based on patch from Neil Rickert of Northern Illinois
		University.
	CONFIG: Fix temporary error handling for LDAP Routing lookups.
		Fix from Andrzej Filip.
	CONTRIB: New version of etrn.pl script and external man page
		(etrn.0) from John Beck of Sun Microsystems.
	LIBMILTER: Protect a free(3) operation from being called with a
		NULL pointer.  Problem noted by Andrey J. Melnikoff.
	LIBMILTER: Protect against more interrupted select() calls.  Based
		on patch from Jose Marcio Martins da Cruz of Ecole Nationale
		Superieure des Mines de Paris.
	New Files:
		contrib/etrn.0
