Theoretically, this gets 27 modified on every change. 28alias.c Does name aliasing in all forms. 29arpadate.c A subroutine which creates ARPANET standard dates. 30bmove.c A core-to-core move. This is in a separate file 31 because it can easily be replaced by a blindingly 32 efficient version on Vaxes. 33bmove.*.s Versions of bmove optimized for specific processors. 34clock.c Routines to implement real-time oriented functions 35 in sendmail -- e.g., timeouts. 36collect.c The routine that actually reads the mail into a temp 37 file. It also does a certain amount of parsing of 38 the header, etc. 39conf.c The configuration file. This contains information 40 that is presumed to be quite static and non- 41 controversial, or code compiled in for efficiency 42 reasons. Most of the configuration is in sendmail.cf. 43conf.h Configuration that must be known everywhere. 44convtime.c A routine to sanely process times. 45daemon.c Routines to implement daemon mode. This version is 46 specifically for Berkeley 4.1 IPC. 47deliver.c Routines to deliver mail. 48err.c Routines to print error messages. 49envelope.c Routines to manipulate the envelope structure. 50headers.c Routines to process message headers. 51macro.c The macro expander. This is used internally to 52 insert information from the configuration file. 53main.c The main routine to sendmail. This file also 54 contains some miscellaneous routines. 55parseaddr.c The routines which do address parsing. 56queue.c Routines to implement message queueing. 57readcf.c The routine that reads the configuration file and 58 translates it to internal form. 59recipient.c Routines that manipulate the recipient list. 60savemail.c Routines which save the letter on processing errors. 61sendmail.h Main header file for sendmail. 62srvrsmtp.c Routines to implement server SMTP. 63stab.c Routines to manage the symbol table. 64stats.c Routines to collect and post the statistics. 65sysexits.c List of error messages associated with error codes 66 in sysexits.h. 67trace.c The trace package. These routines allow setting and 68 testing of trace flags with a high granularity. 69trace.h Definitions needed for the trace package. 70usersmtp.c Routines to implement user SMTP. 71util.c Some general purpose routines used by sendmail. 72version.c A master file for Version.c -- it may not exist in 73 your distribution. 74 75Eric Allman 76 77(Version 4.2, last update 06/07/85 21:34:51) 78
