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.
+8.11.4/8.11.4 2001/05/28
+ Clean up signal handling routines to reduce the chances of heap
+ corruption and other potential race conditions.
+ Terminating and restarting the daemon may not be
+ instantaneous due to this change. Also, non-root users can
+ no longer send out-of-band signals. Problem reported by
+ Michal Zalewski of BindView.
+ If LogLevel is greater than 9 and SASL fails to negotiate an
+ encryption layer, avoid core dump logging the encryption
+ strength. Problem noted by Miroslav Zubcic of Crol.
+ If a server offers "AUTH=" and "AUTH " and the list of mechanisms is
+ different in those two lines, sendmail might not have
+ recognized (and used) all of the offered mechanisms.
+ Fix an IP address lookup problem on Solaris 2.0 - 2.3. Patch
+ from Kenji Miyake.
+ This time, really don't use the .. directory when expanding
+ QueueDirectory wildcards.
+ If a process is interrupted while closing a map, don't try to close
+ the same map again while exiting.
+ Allow local mailers (F=l) to contact remote hosts (e.g., via
+ LMTP). Problem noted by Norbert Klasen of the University
+ of Tuebingen.
+ If Timeout.QueueReturn was set to a value less the time it took
+ to write a new queue file (e.g., 0 seconds), the bounce
+ message would be lost. Problem noted by Lorraine L Goff of
+ Oklahoma State University.
+ Pass map argument vector into map rewriting engine for the regex
+ and prog map types. Problem noted by Stephen Gildea of
+ InTouch Systems, Inc.
+ When closing an LDAP map due to a temporary error, close all of the
+ other LDAP maps which share the original map's connection
+ to the LDAP server. Patch from Victor Duchovni of
+ Morgan Stanley.
+ To detect changes of NDBM aliases files check the timestamp of the
+ .pag file instead of the .dir file. Problem noted by Neil
+ Rickert of Northern Illinois University.
+ Don't treat temporary hesiod lookup failures as permanent. Patch
+ from Werner Wiethege.
+ If ClientPortOptions is set, make sure to create the outgoing socket
+ with the family set in that option. Patch from Sean Farley.
+ Avoid a segmentation fault trying to dereference a NULL pointer
+ when logging a MaxHopCount exceeded error with an empty
+ recipient list. Problem noted by Chris Adams of HiWAAY
+ Internet Services.
+ Fix DSN for "Too many hops" bounces. Problem noticed by Ulrich
+ Windl of the Universitaet Regensburg.
+ Fix DSN for "mail loops back to me" bounces. Problem noticed by
+ Kari Hurtta of the Finnish Meteorological Institute.
+ Portability:
+ OpenBSD has a broken setreuid() implementation.
+ CONFIG: Undo change from 8.11.1: change 501 SMTP reply code back
+ to 553 since it is allowed by DRUMS.
+ CONFIG: Add OSTYPE(freebsd4) for FreeBSD 4.X.
+ DEVTOOLS: install.sh did not properly handle paths in the source
+ file name argument. Noted by Kari Hurtta of the Finnish
+ Meteorological Institute.
+ DEVTOOLS: Add FAST_PID_RECYCLE to compile time options for OpenBSD
+ since it generates random process ids.
+ PRALIASES: Add back adaptive algorithm to deal with different endings
+ of entries in the database (with/without trailing '\0').
+ Patch from John Beck of Sun Microsystems.
+ New Files:
+ cf/ostype/freebsd4.m4
