1/*- 2 * @(#)READ_ME 8.12 (Berkeley) 11/13/94 3 */ 4 5 SENDMAIL RELEASE 8 6 7This directory has the latest sendmail software from Berkeley. See 8doc/op/op.me for a summary of changes since 5.67. 9 10Report any bugs to sendmail@CS.Berkeley.EDU. 11 12The latest version of sendmail is kept on FTP.CS.Berkeley.EDU, directory 13/ucb/sendmail; check there for the latest revision. 14 15 16+--------------+ 17| MANUAL PAGES | 18+--------------+ 19 20The sendmail manual pages use contemporary Berkeley troff macros. If 21your system does not process these manual pages, you can pick up the 22new macros in a BSD Net/2 FTP site (e.g. on FTP.UU.NET, the files 23/systems/unix/bsd-sources/share/tmac/me/strip.sed and 24/systems/unix/bsd-sources/share/tmac/*). 25 26The strip.sed file is only used in installation. 27 28After installation, edit tmac.doc and tmac.andoc to reflect the 29installation path of the tmac files. Those files contain pointers to 30/usr/share/tmac/, and those pointers are not changed by the `make 31install` process. 32 33Rename the existing tmac.an to be tmac.an.old, and rename tmac.andoc 34to be tmac.an. 35 36tmac.an will choose between tmac.an.old, your old macros, or tmac.doc, 37which are the new macros, so that both the new man pages and the 38existing man pages will be translated properly. 39 40I'm also told that the groff distribution from MIT has a tmac.doc 41macro set that is compatible with these macros. 42 43 44+-----------------------+ 45| RELATED DOCUMENTATION | 46+-----------------------+ 47 48There are other files you should read. Rooted in this directory are: 49 50 CHANGES-R5-R8 51 Describes changes between Release 5 and Release 8 of sendmail. 52 There are some things that may behave somewhat differently. 53 For example, the rules governing when :include: files will 54 be read have been tightened up for security reasons. 55 FAQ 56 Answers to Frequently Asked Questions. 57 KNOWNBUGS 58 Known bugs in the current release. I try to keep this up 59 to date -- get the latest version from FTP.CS.Berkeley.EDU 60 in /ucb/sendmail/KNOWNBUGS. 61 RELEASE_NOTES 62 A detailed description of the changes in each version. This 63 is quite long, but informative. 64 src/READ_ME 65 Details on compiling and installing sendmail. 66 cf/README 67 Details on configuring sendmail. 68 doc/op/op.me 69 The sendmail Installation & Operations Guide. Be warned: if 70 you are running this off on SunOS or some other system with an 71 old version of -me, you need to add the following macro to the 72 macros: 73 74 .de sm 75 \s-1\\$1\\s0\\$2 76 .. 77 78 This sets a word in a smaller pointsize. 79 80 81+--------------+ 82| RELATED RFCS | 83+--------------+ 84 85There are several related RFCs that you may wish to read -- they are 86available via anonymous FTP to several sites, including nic.ddn.mil 87(directory rfc), ftp.nisc.sri.com (rfc), nis.nsf.net (RFC), 88nisc.jvnc.net (rfc), venera.isi.edu (in-notes), and wuarchive.wustl.edu 89(info/rfc). They can also be retrieved via electronic mail by sending 90email to one of: 91 92 mail-server@nisc.sri.com 93 Put "send rfcNNN" in message body 94 nis-info@nis.nsf.net 95 Put "send RFCnnn.TXT-1" in message body 96 sendrfc@jvnc.net 97 Put "RFCnnn" as Subject: line 98 99Important RFCs for electronic mail are: 100 101 RFC821 SMTP protocol 102 RFC822 Mail header format 103 RFC974 MX routing 104 RFC976 UUCP mail format 105 RFC1123 Host requirements (modifies 821, 822, and 974) 106 RFC1413 Identification server 107 RFC1425 SMTP Service Extensions (ESMTP spec) 108 RFC1426 SMTP Service Extension for 8bit-MIMEtransport 109 RFC1427 SMTP Service Extension for Message Size Declaration 110 RFC1521 MIME: Multipurpose Internet Mail Extensions 111 RFC1344 Implications of MIME for Internet Mail Gateways 112 RFC1428 Transation of Internet Mail from Just-Send-8 to 113 8-bit SMTP/MIME 114 115Other standards that may be of interest (but which are less directly 116relevant to sendmail) are: 117 118 RFC987 Mapping between RFC822 and X.400 119 RFC1049 Content-Type header field (extension to RFC822) 120 121Warning to AIX users: this version of sendmail does not implement 122MB, MR, or MG DNS resource records, as defined as experiments in 123RFC883. 124 125 126+-------------------+ 127| DATABASE ROUTINES | 128+-------------------+ 129 130IF YOU WANT TO RUN THE NEW BERKELEY DB SOFTWARE: **** DO NOT **** 131use the version that was on the Net2 tape -- it has a number of 132nefarious bugs that were bad enough when I got them; you shouldn't have 133to go through the same thing. Instead, get a new version via public 134FTP from ftp.CS.Berkeley.EDU, file ucb/4bsd/db.tar.Z. This software 135is highly recommended; it gets rid of several stupid limits, it's much 136faster, and the interface is nicer to animals and plants. You will 137also probably find that you have to add -I/where/you/put/db/include 138to the sendmail makefile to get db.h to work properly. 139 140Be sure you remove ndbm.h and ndbm.o from the db distribution. These 141will cause problems with sendmail because sendmail already understands 142about NEWDB and NDBM coexisting. 143 144 145+--------------------+ 146| Host Name Services | 147+--------------------+ 148 149If you compile with NAMED_BIND (the default) sendmail will use 150DNS (the Domain Name System) for most host name lookups. If 151you do not have DNS running at your site you may have to turn 152this off to cause sendmail to use NIS and/or the /etc/hosts file. 153In particular, on SunOS you have to choose to use DNS (which 154you should do if you are attached to the Internet, otherwise 155you lose MX records, which are required) or NIS -- there is no 156way to try both. 157 158If you are using NIS and /etc/hosts, it is critical that you 159list the long (fully qualified) name first in the /etc/hosts file 160used to build the NIS database. For example, the line should read 161 162 128.32.149.68 mastodon.CS.Berkeley.EDU mastodon 163 164**** NOT **** 165 166 128.32.149.68 mastodon mastodon.CS.Berkeley.EDU 167 168If you use the wrong order, sendmail will conclude that your 169canonical name is the short version and use that in messages. 170The name "mastodon" doesn't mean much outside of Berkeley, 171and so this creates incorrect and unreplyable messages. 172 173 174+-------------+ 175| USE WITH MH | 176+-------------+ 177 178This version of sendmail notices and reports certain kinds of SMTP 179protocol violations that were ignored by older versions. If you 180are running MH you may wish to install the patch in contrib/mh.patch 181that will prevent these warning reports. This patch also works 182with the old version of sendmail, so it's safe to go ahead and 183install it. 184 185 186+-----------+ 187| MAKEFILES | 188+-----------+ 189 190The Makefiles in this release use the new Berkeley "make" that is 191available in BSD Net/2 and 4.4BSD. If you are using this version 192of make, you may notice one or two places where the Makefile includes 193"../../Makefile.inc". This file is not included with the sendmail 194distribution because it's not part of sendmail. However, it is, 195in toto: 196 197 # @(#)Makefile.inc 8.1 (Berkeley) 6/6/93 198 199 BINDIR?= /usr/sbin 200 201The other directories should all have Makefile.dist files that work 202on the old make, albeit without all the niceties included. 203 204You can also get a new Berkeley make from the Net2 release (available 205on many public FTP archives). This version should also interpret old 206Makefiles, so you could drop it in as your default make. 207 208For more details, see src/READ_ME. 209 210 211+---------------------+ 212| DIRECTORY STRUCTURE | 213+---------------------+ 214 215The structure of this directory tree is: 216 217cf Source for Berkeley configuration files. These are 218 different than what you've seen before. They are a 219 fairly dramatic rewrite, requiring the new sendmail 220 (since they use new features). 221contrib Some contributed tools to help with sendmail. THESE 222 ARE NOT SUPPORTED by Berkeley -- contact the original 223 authors if you have problems. (This directory is not 224 on the 4.4BSD tape.) 225doc Documentation. If you are getting source, read 226 op.me -- it's long, but worth it. 227mail.local The source for the local delivery agent used for 4.4BSD. 228 THIS IS NOT PART OF SENDMAIL! and may not compile 229 everywhere, since it depends on some 4.4-isms. Warning: 230 it does mailbox locking differently than other systems. 231mailstats Statistics printing program. It has the pathname of 232 sendmail.st compiled in, so if you've changed that, 233 beware. This isn't all that useful. 234makemap A program that creates the keyed maps used by the $( ... $) 235 construct in sendmail. It is primitive but effective. 236 It takes a very simple input format, so you will probably 237 expect to preprocess must human-convenient formats 238 using sed scripts before this program will like them. 239 But it should be functionally complete. 240praliases A program to print the DBM version of the aliases file. 241 It hasn't been converted to understand the new Berkeley 242 DB format (which we are using). 243rmail Source for rmail(8). This is used as a delivery 244 agent for for UUCP, and could presumably be used by 245 other non-socket oriented mailers. Older versions of 246 rmail are probably deficient. RMAIL IS NOT PART OF 247 SENDMAIL!!! The 4.4BSD source is included for you to 248 look at or try to port to your system. I know it doesn't 249 compile on {SunOS, HP-UX, OSF/1, other} (pick one). 250smrsh The "sendmail restricted shell", which can be used as 251 a replacement for /bin/mail in the prog mailer to provide 252 increased security control. NOT PART OF SENDMAIL! 253src Source for the sendmail program itself. 254test Some test scripts (currently only for compilation aids). 255
