There is 18also a Makefile.dist which is much less clever, but works on the old 19traditional make. You can use this using: 20 21 make -f Makefile.dist 22 23If you are compiling on SunOS, you must use -Bstatic -- if you do not, 24frozen configuration files fail in bizarre ways and you will open up 25several security holes. 26 27If you use both -DDBM and -DNEWDB, you must delete the module ndbm.o 28from libdb.a. This compatibility module maps ndbm calls into DB 29calls, and breaks things rather badly. 30 31The following list describes the files in this directory: 32 33Makefile The makefile used here; this version only works with 34 the new Berkeley make. 35Makefile.dist A trimmed down version of the makefile that works with 36 the old make. 37READ_ME This file. 38TODO New features to be put in (maybe) at some time. 39Version.c The version number and information about this 40 version of sendmail. Theoretically, this gets 41 modified on every change. 42alias.c Does name aliasing in all forms. 43arpadate.c A subroutine which creates ARPANET standard dates. 44clock.c Routines to implement real-time oriented functions 45 in sendmail -- e.g., timeouts. 46collect.c The routine that actually reads the mail into a temp 47 file. It also does a certain amount of parsing of 48 the header, etc. 49conf.c The configuration file. This contains information 50 that is presumed to be quite static and non- 51 controversial, or code compiled in for efficiency 52 reasons. Most of the configuration is in sendmail.cf. 53conf.h Configuration that must be known everywhere. 54convtime.c A routine to sanely process times. 55daemon.c Routines to implement daemon mode. This version is 56 specifically for Berkeley 4.1 IPC. 57deliver.c Routines to deliver mail. 58err.c Routines to print error messages. 59envelope.c Routines to manipulate the envelope structure. 60headers.c Routines to process message headers. 61macro.c The macro expander. This is used internally to 62 insert information from the configuration file. 63main.c The main routine to sendmail. This file also 64 contains some miscellaneous routines. 65parseaddr.c The routines which do address parsing. 66queue.c Routines to implement message queueing. 67readcf.c The routine that reads the configuration file and 68 translates it to internal form. 69recipient.c Routines that manipulate the recipient list. 70savemail.c Routines which save the letter on processing errors. 71sendmail.h Main header file for sendmail. 72srvrsmtp.c Routines to implement server SMTP. 73stab.c Routines to manage the symbol table. 74stats.c Routines to collect and post the statistics. 75sysexits.c List of error messages associated with error codes 76 in sysexits.h. 77trace.c The trace package. These routines allow setting and 78 testing of trace flags with a high granularity. 79trace.h Definitions needed for the trace package. 80usersmtp.c Routines to implement user SMTP. 81util.c Some general purpose routines used by sendmail. 82version.c A master file for Version.c -- it may not exist in 83 your distribution. 84 85Eric Allman 86 87(Version 6.3, last update 02/12/93 11:51:08) 88
