203 rather than using fcntl-based locking. Fcntl locking
204 has some semantic gotchas, but many vendor systems
205 also interface it to lockd(8) to do NFS-style locking.

264 should be declared in <errno.h>), and it should be used
265 instead of sys_errlist.
266NEEDGETOPT Define this if you need a reimplementation of getopt(3).
267 On some systems, getopt does very odd things if called
268 to scan the arguments twice. This flag will ask sendmail
269 to compile in a local version of getopt that works
270 properly.

456 flag but doesn't pay attention to it when trying to bind a
457 socket to a recently closed port.

471USERDB Define this to 1 to include support for the User Information
472 Database. Implied by NEWDB or HESIOD. You can use
473 -DUSERDB=0 to explicitly turn it off.
474IDENTPROTO Define this as 1 to get IDENT (RFC 1413) protocol support.
475 This is assumed unless you are running on Ultrix or
476 HP-UX, both of which have a problem in the UDP
477 implementation. You can define it to be 0 to explicitly
478 turn off IDENT protocol support. If defined off, the code
479 is actually still compiled in, but it defaults off; you

496 This is assumed unless you are running on Ultrix or
497 HP-UX, both of which have a problem in the UDP
498 implementation. You can define it to be 0 to explicitly
499 turn off IDENT protocol support. If defined off, the code

481 configuration file.
482IP_SRCROUTE Define this to 1 to get IP source routing information
483 displayed in the Received: header. This is assumed on
484 most systems, but some (e.g., Ultrix) apparently have a
485 broken version of getsockopt that doesn't properly
486 support the IP_OPTIONS call. You probably want this if
487 your OS can cope with it. Symptoms of failure will be that
488 it won't compile properly (that is, no support for fetching
489 IP_OPTIONs), or it compiles but source-routed TCP connections
490 either refuse to open or open and hang for no apparent reason.
491 Ultrix and AIX3 are known to fail this way.

517NETINET6 Set this to get IPv6 support. Other configuration may
518 be needed in conf.h for your particular operating system.
519 Also, DaemonPortOptions must be set appropriately for
520 sendmail to accept IPv6 connections.
496NETISO Define this to get ISO networking support.
497NETUNIX Define this to get Unix domain networking support. Defined
498 by default. A few bizarre systems (SCO, ISC, Altos) don't
499 support this networking domain.

501 or NETISO.
502NAMED_BIND If non-zero, include DNS (name daemon) support, including
503 MX support. The specs say you must use this if you run
504 SMTP. You don't have to be running a name server daemon
505 on your machine to need this -- any use of the DNS resolver,
506 including remote access to another machine, requires this

532 (notably ConvexOS) to get a C2 Secure system. This
533 option causes mail delivery to be done with the luid of the
534 recipient.
535SHARE_V1 Support for the fair share scheduler, version 1. Setting to
536 1 causes final delivery to be done using the recipients
537 resource limitations. So far as I know, this is only

566SASL Enables SMTP AUTH (RFC 2554). This requires the Cyrus SASL
567 library (ftp://ftp.andrew.cmu.edu/pub/cyrus-mail/). Please
568 install at least version 1.5.13. See below for further
569 information: SASL COMPILATION AND CONFIGURATION. If your
570 SASL library is older than 1.5.10, you have to set this
571 to its version number using a simple conversion: a.b.c
572 -> c + b*100 + a*10000, e.g. for 1.5.9 define SASL=10509.
573 Note: Using an older version than 1.5.5 of Cyrus SASL is
574 not supported. Starting with version 1.5.10, setting SASL=1
575 is sufficient. Any value other than 1 (or 0) will be
576 compared with the actual version found and if there is a
577 mismatch, compilation will fail.
578EGD Define this if your system has EGD installed, see
579 http://www.lothar.com/tech/crypto/ . It should be used to
580 seed the PRNG for STARTTLS if HASURANDOMDEV is not defined.
581STARTTLS Enables SMTP STARTTLS (RFC 2487). This requires OpenSSL
582 (http://www.OpenSSL.org/) and sfio (see below).
583 See STARTTLS COMPILATION AND CONFIGURATION for further
584 information.
585TLS_NO_RSA Turn off support for RSA algorithms in STARTTLS.
586SFIO Uses sfio instead of stdio. sfio is available from AT&T
587 (http://www.research.att.com/sw/tools/sfio/). If this
588 compile flag is set, confSTDIO_TYPE must be set to portable.
589 This compile flag is necessary for STARTTLS; it also
590 enables the security layer of SASL. The sfio include file
591 stdio.h must be installed in a subdirectory called sfio,
592 i.e., if you install sfio in /usr/local, stdio.h should
593 be in /usr/local/include/sfio, and libsfio.a should be in

632| STARTTLS COMPILATION AND CONFIGURATION |
633+----------------------------------------+
634
635Please read the docs accompanying the OpenSSL library and sfio.
636You have to compile and install both libraries before you can compile
637sendmail. See devtools/README how to set the correct compile time
638parameters; you should at least set the following variables:
639
640define(`confSTDIO_TYPE', `portable')
641APPENDDEF(`confENVDEF', `-DSFIO')
642APPENDDEF(`confLIBS', `-lsfio')
643APPENDDEF(`conf_sendmail_ENVDEF', `-DSTARTTLS')
644APPENDDEF(`conf_sendmail_LIBS', `-lssl -lcrypto')
645
646Configuration information can be found in doc/op/op.me (required
647certificates) and cf/README (how to tell sendmail about certificates).
648
649To perform an initial test, connect to your sendmail daemon
650(telnet localhost 25) and issue a EHLO localhost and see whether
651250-STARTTLS
652is in the response. If it isn't, run the daemon with
653-O LogLevel=14
654and try again. Then take a look at the logfile and see whether
655there are any problems listed about permissions (unsafe files)
656or the validity of X.509 certificates.
657
658Note: sfio must be used in all libraries with which sendmail exchanges
659file pointers. That is, libsmutil must be compiled with sfio, which
660is accomplished by the above config parameters. Another example is
661PH map support. This does not apply to the usual libraries, e.g.,
662OpenSSL, Berkeley DB, Cyrus SASL.

668+------------------------------------+
669| SASL COMPILATION AND CONFIGURATION |
670+------------------------------------+
671
672Please read the docs accompanying the library (INSTALL and README).
673If you use Berkeley DB for Cyrus SASL then you must compile sendmail
674with the same version of Berkeley DB.
675
676You have to select and install authentication mechanisms and tell
677sendmail where to find the sasl library and the include files (see
678devtools/README for the parameters to set). Setup the required
679users and passwords as explained in the SASL documentation. See
680also cf/README for authentication related options (esp. DefaultAuthInfo
681if you want authentication between MTAs).
682
683To perform an initial test, connect to your sendmail daemon
684(telnet localhost 25) and issue a EHLO localhost and see whether
685250-AUTH ....
686is in the response. If it isn't, run the daemon with
687-O LogLevel=14
688and try again. Then take a look at the logfile and see whether
689there are any security related problems listed (unsafe files).

615 support programs and scripts that need to find sendmail.cf. You

742 NETINFO systems use NETINFO to determine the location of
743 sendmail.cf. The full path to sendmail.cf is stored as the value of
744 the "sendmail.cf" property in the "/locations/sendmail"
745 subdirectory of NETINFO. Set the value of this property to
746 "/etc/mail/sendmail.cf" (without the quotes) to use this new
747 default location for Sendmail 8.10.0 and higher.

749ControlSocket permissions
750 Paraphrased from BIND 8.2.1's README:
751
752 Solaris and other pre-4.4BSD kernels do not respect ownership or
753 protections on UNIX-domain sockets. The short term fix for this is to
754 override the default path and put such control sockets into root-
755 owned directories which do not permit non-root to r/w/x through them.
756 The long term fix is for all kernels to upgrade to 4.4BSD semantics.

691 To the best of my knowledge, Solaris does not have the
692 gethostbyname problem described above. However, it does
693 have another one:
694
695 From a correspondent:
696
697 For solaris 2.2, I have
698
699 hosts: files dns
700
701 in /etc/nsswitch.conf and /etc/hosts has to have the fully
702 qualified host name. I think "files" has to be before "dns"
703 in /etc/nsswitch.conf during bootup.
704
705 From another correspondent:
706
707 When running sendmail under Solaris, the gethostbyname()
708 hack in conf.c which should perform proper canonicalization
709 of host names could fail. Result: the host name is not
710 canonicalized despite the hack, and you'll have to define $j
711 and $m in sendmail.cf somewhere.
712
713 The reason could be that /etc/nsswitch.conf is improperly
714 configured (at least from sendmail's point of view). For
715 example, the line
716
717 hosts: files nisplus dns
718
719 will make gethostbyname() look in /etc/hosts first, then ask
720 nisplus, then dns. However, if /etc/hosts does not contain
721 the full canonicalized hostname, then no amount of
722 gethostbyname()s will work.
723
724 Solution (or rather, a workaround): Ask nisplus first, then
725 dns, then local files:
726
727 hosts: nisplus dns [NOTFOUND=return] files

729 The Solaris "syslog" function is apparently limited to something

781 If you built sendmail 8.8.1 through 8.8.4 inclusive on a Solaris 2.5

925 The Ultrix 4.5 Y2K patch (ULTV45-022-1) has changed the resolver

1207
1208 Some pre-glibc distributions of Linux include a syslog.h that does
1209 not work properly with SFIO. You can fix this by adding
1210 "#include <syslog.h>" to the SFIO version of stdio.h as the very

1213AIX 4.X
1214 The AIX 4.X linker uses library paths specified during compilation
1215 using -L for run-time shared library searches. Therefore, it is
1216 vital that relative and unsafe directory paths not be using when
1217 compiling sendmail. Because of this danger, by default, compiles
1218 on AIX use the -blibpath option to limit shared libraries to
1219 /usr/lib and /lib. If you need to allow more directories, such as
1220 /usr/local/lib, modify your devtools/Site/site.AIX.4.2.m4,
1221 site.AIX.4.3.m4, and/or site.AIX.4.x.m4 file(s) and set confLDOPTS
1222 approriately. For example:
1223
1224 define(`confLDOPTS', `-blibpath:/usr/lib:/lib:/usr/local/lib')
1225
1226 Be sure to only add (safe) system directories.
1227
1228 The AIX version of GNU ld also exhibits this problem. If you are
1229 using that version, instead of -blibpath, use its -rpath option.
1230 For example:

1423 BIND 8.X returns HOST_NOT_FOUND instead of TRY_AGAIN on temporary

1427 database won't succeed.

1287 a "HELO hostname" when using the 'system' or 'telnet' mailmethod.
1288
1289 The fix is to include -DZMAILER in the compilation, which will
1290 cause it to use "HELO hostname" (which Z-mail apparently requires
1291 as well. :)

1436strtoul
1437 Some compilers (notably gcc) claim to be ANSI C but do not
1438 include the ANSI-required routine "strtoul". If your compiler
1439 has this problem, you will get an error in srvrsmtp.c on the
1440 code:
1441
1442 # ifdef defined(__STDC__) && !defined(BROKEN_ANSI_LIBRARY)
1443 e->e_msgsize = strtoul(vp, (char **) NULL, 10);

1293LDAP
1294 LDAP was provided by Booker Bense <bbense+ldap@stanford.edu> of
1295 Stanford University. From Booker:
1464OpenSSL
1465 OpenSSL versions prior to 0.9.6 use a macro named Free which
1466 conflicts with existing macro names on some platforms, such as
1467 AIX.

1297 - The patch attached to this message implements an Ldap map class.
1298 Currently we are using this at stanford to support campus-wide
1299 email addressing. More information can be found at
1300 http://www.stanford.edu/~bbense/Inst.html.
1469PH
1470 PH support is provided by Mark Roth <roth@uiuc.edu>. The map is
1471 described at http://www-wsg.cso.uiuc.edu/sendmail/patches/ .
1472 Please contact Mark Roth for support and questions regarding the
1473 map.
1301
1474
1302 - Currently we are using the ldap map as follows:
1303
1304 Kluser ldapx
1305 -h"localhost borax.stanford.edu borate.stanford.edu boron.stanford.edu"
1306 -k"mailacceptinggeneralid=%s" -v maildrop
1307
1308 and in Rule set S5
1309
1310 # Now attempt to lookup in luser (ldap map)
1311 R< $L > $+ $: < $L > $( luser $1 $)
1312 R< $* > $+ @ $+ $: < $3 > $2 Rewrite if forward
1313
1314 - The map definition supports most of the standard Map args plus most
1315 of the command line options of ldapsearch. The software is currently
1316 limited to only accepting the first entry returned. It expects that
1317 the map defines an ldap filter that returns at most 1 valid entry.
1318 It requires the ldap and lber libraries from the Umich Ldap3.2
1319 release.
1320
1321 The software has been in production on Solaris.2.5.1 at Stanford
1322 for over 2 years.
1323
1324 The LDAP map supports both the UMich LDAP 3.2 and 3.3 libraries as
1325 well as the OpenLDAP (http://www.openldap.org/) libraries.

1327TCP Wrappers
1328 If you are using -DTCPWRAPPERS to get TCP Wrappers support you will
1329 also need to install libwrap.a and modify your site.config.m4 file
1330 or the generated Makefile to include -lwrap in the LIBS line
1331 (make sure that INCDIRS and LIBDIRS point to where the tcpd.h and
1332 libwrap.a can be found).
