141139Sbostic/*- 2*57979Seric * @(#)READ_ME 6.4 (Berkeley) 02/14/93 336585Sbostic */ 410221Seric 557210SericTHIS IS AN ALPHA VERSION OF SENDMAIL. DON'T EVEN THINK ABOUT USING IT 657210SericIN A HEAVY PRODUCTION ENVIRONMENT. We've been running it (in various 757210Sericforms) at Berkeley for several months, but our environment is far from 857210Sericgeneral. In particular, it hasn't been heavily tested for non-SMTP 957210Sericenvironments. The good news is that most of the changes have been 1057210SericInternet-related, and that has been tested. 1157210Seric 1257210SericREPORT ANY BUGS to sendmail@CS.Berkeley.EDU. 1357210Seric 1457210SericTHIS IS COPYRIGHTED CODE. BY COMPILING AND RUNNING THIS CODE YOU AGREE 1557210Sericto upgrade to the production release when it comes out. You understand 1657210Sericthat we hope this will be by March, but if there are serious problems 1757210Sericit may be longer than that. 1857210Seric 19*57979SericYou don't have to install mail.local to run the new version of sendmail. 20*57979SericMany versions of /bin/mail take a "-d" flag or do local delivery already. 21*57979SericIn particular, mail.local is largely specific to 4.4 BSD, and will not 22*57979Sericbe easy to compile elsewhere. It was written by Keith Bostic, not myself, 23*57979Sericand was not intended for the "general case". 2457210Seric 25*57979SericThere are several related RFCs that you may wish to read -- they are 26*57979Sericavailable via anonymous FTP to several sites, including nic.ddn.mil 27*57979Seric(directory rfc), ftp.nisc.sri.com (rfc), nis.nsf.net (RFC), 28*57979Sericnisc.jvnc.net (rfc), venera.isi.edu (in-notes), and wuarchive.wustl.edu 29*57979Seric(info/rfc). They can also be retrieved via electronic mail by sending 30*57979Sericemail to one of: 31*57979Seric 32*57979Seric mail-server@nisc.sri.com 33*57979Seric Put "send rfcNNN" in message body 34*57979Seric nis-info@nis.nsf.net 35*57979Seric Put "send RFCnnn.TXT-1" in message body 36*57979Seric sendrfc@jvnc.net 37*57979Seric Put "RFCnnn" as Subject: line 38*57979Seric 39*57979SericImportant RFCs for electronic mail are: 40*57979Seric 41*57979Seric RFC821 SMTP protocol 42*57979Seric RFC822 Mail header format 43*57979Seric RFC974 MX routing 44*57979Seric RFC976 UUCP mail format 45*57979Seric RFC1123 Host requirements (modifies 821, 822, and 974) 46*57979Seric 47*57979SericOther standards that may be of interest (but which are less directly 48*57979Sericrelevant to sendmail) are: 49*57979Seric 50*57979Seric RFC931 Authentication server 51*57979Seric RFC987 Mapping between RFC822 and X.400 52*57979Seric RFC1049 Content-Type header field (extension to RFC822) 53*57979Seric 54*57979SericUnfortunately, for a variety of reasons the Makefiles are for the new 55*57979SericBerkeley "make" and will not work on the old, traditional make. I urge 56*57979Sericyou to get this make from Net2 (available on many public FTP archives). 57*57979SericFailing that, some directories have a "Makefile.dist" that will work on 58*57979Sericolder versions of make (but don't have the niceties included). 59*57979Seric 60*57979SericSimilar comments apply to the man pages -- they use the new Berkeley 61*57979Seric-mandoc macros instead of the -man macros. You can get these from 62*57979SericNet2 as well. 63*57979Seric 64*57979SericIF YOU WANT TO RUN THE NEW BERKELEY DB SOFTWARE: **** DO NOT **** 65*57979Sericuse the version that was on the Net2 tape -- it has a number of 66*57979Sericnefarious bugs that were bad enough when I got them; you shouldn't have 67*57979Sericto go through the same thing. Instead, get a new version via public 68*57979SericFTP from okeeffe.CS.Berkeley.EDU, file pub/db.tar.Z. This software 69*57979Sericis highly recommended; it gets rid of several stupid limits, it's much 70*57979Sericfaster, and the interface is nicer to animals and plants. You will 71*57979Sericalso probably find that you have to add -I/where/you/put/db/include 72*57979Sericto the sendmail makefile to get db.h to work properly. 73*57979Seric 74*57979SericThe structure of this directory tree is: 75*57979Seric 7657210Sericcf Source for Berkeley configuration files. These are 7757210Seric different than what you've seen before. They are a 7857210Seric fairly dramatic rewrite, requiring the new sendmail 7957210Seric (since they use new features). 8057210Sericdoc Documentation. If you are getting source, read 8157210Seric op.me -- it's long, but worth it. 8257210Sericmail.local Source for mail.local(8), a local delivery program. 8357210Seric Older versions of sendmail called /bin/mail with a 8457210Seric special -d flag to mean "really deliver this mail"; 8557210Seric this is a completely new (and much smaller) program 8657210Seric that does absolutely nothing but deliver local mail. 8757635Seric THIS IS SPECIFIC TO 4.4BSD, and is not under my 8857635Seric control. 8957210Sericmailstats Statistics printing program. It has the pathname of 9057210Seric sendmail.st compiled in, so if you've changed that, 9157210Seric beware. This isn't all that useful. 9257210Sericmakemap A program that creates the keyed maps used by the $( ... $) 9357210Seric construct in sendmail. It is primitive but effective. 9457210Seric It takes a very simple input format, so you will probably 9557210Seric expect to preprocess must human-convenient formats 9657210Seric using sed scripts before this program will like them. 9757210Seric But it should be functionally complete. 9857210Sericpraliases A program to print the DBM version of the aliases file. 9957210Seric It hasn't been converted to understand the new Berkeley 10057210Seric DB format (which we are using). 10157210Sericrmail Source for rmail(8). This is used as a delivery 10257210Seric agent for for UUCP, and could presumably be used by 10357635Seric other non-socket oriented mailers. Older versions of 10457635Seric rmail are probably deficient. 10554987Sericsrc Source for the sendmail program itself. 106
