A new release of the UIUC/NIU version of IDA sendmail is now available for anon-FTP from uxc.cso.uiuc.edu in pub/sendmail-5.65+IDA-1.4.2.tar.Z . The original IDA enhancements, plus the UIUC/NIU and contributed changes, provide the following: * support for mail11v3 for DECnet sites (optional) * support for Dbm(3) files - dbm, ndbm, sdbm, mdbm, and gdbm - allows pathalias database to be directly used - allows choice of mailer to be table driven - allows UUCP and domain name aliasing - optional support to access Sun NIS (aka YP) DBM databases * improved support of MX records * split header rewriting between envelope and headers * improved test mode * support for multi-token matches in .cf macros and classes * batched SMTP support * allow set (class) declarations to use programs as well as files to define a set * delayed macro evauation using $&x syntax * RFC822 quoted macro expansion using $!x syntax * an excellent general purpose m4 template for .cf file generation - supports pure UUCP site requirements - supports pure Internet site requirements - supports a hybrid of UUCP site and Internet site - supports hidden and isolated local area networks connected via a gateway (either UUCP or IP) to the Internet - provides NIS (aka YP) aliases (optional) - provides DECnet gateway support - supports genericfrom database mapping actual user names to generic user names. - supports pathalias database - support UUCP and domain name aliasing This release is chiefly a bugfix and increased portability release. Neil Rickert has substantially improved the DecNet gateway rulesets. Changes in 5.65/1.4.2 from the previous (1.3.5) release: Tested now on Next, SGI-IRIS (IRIX 3.3.1), HP-Apollo (10.3). Now compiles and runs with gcc (tested w. 1.37.1 on Sequent, VAX, Pyramid, then I got tired). No longer needs -pcc flag on Convex. Installation instructions now included. See INSTALL. Loops in myhostname() if NAMED_BIND #define'd and all nameservers are unreachable. Not needed if hostname returns the FQDN. Fixed randomization of equal weighted MX records. Change auto variables in tTflag() to unsigned int. This closes a nasty security hole. Gutted load averaging mess from conf.c and replaced with getloadavg.c from the X11R4 distribution. The calculated load average can be printed using the -d3.1 debug flag. deliver() now configured to release non-inheritable flock() (emulated with lockf()) before fork() and to re-flock() in child. The #include <file.h> for testing whether to emulate flock() has been moved from the various *.c files to sendmail.h. Re-named #define SYSTEM5 to #define SYSV. Isolated code in recipient.c that does fuzzy-matching of recipient names. Now disabled by default. See FUZZY in conf.h All tokens following #else and #endif statements are now in comments. This appeases the more discerning pre-processors. Deleted OUTPUT_PID in conf.h. The sendmail.fc freeze file code is now included only if _PATH_SENDMAILFC is defined in conf.h (see next). Because the definition (or lack) of the _PATH_SENDMAIL* #define's now controls whether certain code is compiled, the contents of pathnames.h has been absorbed into conf.h . This localizes site-specific customizations to conf.h and the Makefile. Simplified locking in mapinit(). Now only the alias file is opened O_RDWR when OpMode == MD_INITALIAS. All others are O_RDONLY. The same situation for flock(): LOCK_SH unless re-writing the alias database. Anything re-writing a DBM database should be using exclusive locks which will block a LOCK_SH request. This provides better support for NFS-mounted, read-only filesystems containing the mail database files. ida/aux/dbm.c now pays attention to the return value of flock(). The fetch and dump operations apply shared locks, all others apply exclusive locks. binmail sources can now be compiled to use ..../mail/username.lock style locking. Handy for systems that NFS mount the mail spool area. Whatever style you use, make sure all the players agree or BAD THINGS may happen. The values of the $r and $q macros are now saved in the queue files. Neil Rickert has again improved ida/cf/Sendmail.mc. Among other things he's eliminated the need for using newaliases.cf when forward aliases are used. Re-write all current aliases that are of the form user@host.domain: something to user%host.domain@al.ias.UUCP: something and add the following to mailertable: LOCAL!localhost al.ias.UUCP /pbp -- Paul Pomes UUCP: {att,iuvax,uunet}!uiucuxc!paul Internet, BITNET: paul@uxc.cso.uiuc.edu US Mail: UofIllinois, CSO, 1304 W Springfield Ave, Urbana, IL 61801-2910
