For installation instructions, please read the document ../doc/op.me: nroff -me ../doc/op.me The following list describes the files in this directory: Makefile The makefile used here; this is created from makefile.m4. Makefile.m4 A makefile template. READ_ME This file. TODO New features to be put in (maybe) at some time. Version.c The version number and information about this version of sendmail. Theoretically, this gets modified on every change. alias.c Does name aliasing in all forms. arpadate.c A subroutine which creates ARPANET standard dates. bmove.c A core-to-core move. This is in a separate file because it can easily be replaced by a blindingly efficient version on Vaxes. bmove.*.s Versions of bmove optimized for specific processors. clock.c Routines to implement real-time oriented functions in sendmail -- e.g., timeouts. collect.c The routine that actually reads the mail into a temp file. It also does a certain amount of parsing of the header, etc. conf.c The configuration file. This contains information that is presumed to be quite static and non- controversial, or code compiled in for efficiency reasons. Most of the configuration is in sendmail.cf. conf.h Configuration that must be known everywhere. convtime.c A routine to sanely process times. daemon.c Routines to implement daemon mode. This version is specifically for Berkeley 4.1 IPC. deliver.c Routines to deliver mail. err.c Routines to print error messages. envelope.c Routines to manipulate the envelope structure. headers.c Routines to process message headers. macro.c The macro expander. This is used internally to insert information from the configuration file. main.c The main routine to sendmail. This file also contains some miscellaneous routines. parseaddr.c The routines which do address parsing. queue.c Routines to implement message queueing. readcf.c The routine that reads the configuration file and translates it to internal form. recipient.c Routines that manipulate the recipient list. savemail.c Routines which save the letter on processing errors. sendmail.h Main header file for sendmail. srvrsmtp.c Routines to implement server SMTP. stab.c Routines to manage the symbol table. stats.c Routines to collect and post the statistics. sysexits.c List of error messages associated with error codes in sysexits.h. trace.c The trace package. These routines allow setting and testing of trace flags with a high granularity. trace.h Definitions needed for the trace package. usersmtp.c Routines to implement user SMTP. util.c Some general purpose routines used by sendmail. version.c A master file for Version.c -- it may not exist in your distribution.
