96faada8 | 33 | ** SENDMAIL -- Post mail to a set of destinations. |
b3cbe40f EA |
34 | ** |
35 | ** This is the basic mail router. All user mail programs should | |
96faada8 | 36 | ** call this routine to actually deliver mail. Sendmail in |
b3cbe40f EA |
37 | ** turn calls a bunch of mail servers that do the real work of |
38 | ** delivering the mail. | |
39 | ** | |
3199e4f3 EA |
40 | ** Sendmail is driven by tables read in from /usr/lib/sendmail.cf |
41 | ** (read by readcf.c). Some more static configuration info, | |
42 | ** including some code that you may want to tailor for your | |
43 | ** installation, is in conf.c. You may also want to touch | |
44 | ** daemon.c (if you have some other IPC mechanism), acct.c | |
45 | ** (to change your accounting), names.c (to adjust the name | |
46 | ** server mechanism). | |
b3cbe40f EA |
47 | ** |
48 | ** Usage: | |
7338e3d4 | 49 | ** /usr/lib/sendmail [flags] addr ... |
b3cbe40f | 50 | ** |
