96faada8 | 31 | ** SENDMAIL -- Post mail to a set of destinations. |
b3cbe40f EA |
32 | ** |
33 | ** This is the basic mail router. All user mail programs should | |
96faada8 | 34 | ** call this routine to actually deliver mail. Sendmail in |
b3cbe40f EA |
35 | ** turn calls a bunch of mail servers that do the real work of |
36 | ** delivering the mail. | |
37 | ** | |
3199e4f3 EA |
38 | ** Sendmail is driven by tables read in from /usr/lib/sendmail.cf |
39 | ** (read by readcf.c). Some more static configuration info, | |
40 | ** including some code that you may want to tailor for your | |
41 | ** installation, is in conf.c. You may also want to touch | |
42 | ** daemon.c (if you have some other IPC mechanism), acct.c | |
43 | ** (to change your accounting), names.c (to adjust the name | |
44 | ** server mechanism). | |
b3cbe40f EA |
45 | ** |
46 | ** Usage: | |
7338e3d4 | 47 | ** /usr/lib/sendmail [flags] addr ... |
b3cbe40f | 48 | ** |
7338e3d4 | 49 | ** See the associated documentation for details. |
