|
20 The \fBsendmail.cf\fR and \fBsubmit.cf\fR files are the configuration files for \fBsendmail\fR(1M). Starting with version 8.12 of \fBsendmail\fR, which was shipped with version 9 of the Solaris operating system, two configuration files are used for submission and transmission of mail, instead of only \fBsendmail.cf\fR, as before. These are: |
|

|
26 .ad |
|
27 .RS 15n |
|
28 .rt |
|
29 Remains the principal \fBsendmail\fR configuration file. Used for the Mail Transmission Agent (MTA). |

|
37 .ad |

|
40 Used for the Mail Submission Program (MSP). The MSP is used to submit mail messages. Unlike the MTA, it does not run as an SMTP daemon. |
|
41 .RE |

|
45 The MSP does not require root privileges, thus the two-file model provides better security than the pre-\fBsendmail\fR 8.12 model, in which the MSP ran as a daemon and required root privileges. |
|
46 .sp |
|
47 .LP |
|
48 In the default \fBsendmail\fR configuration, \fBsendmail\fR uses \fBsubmit.cf\fR, as indicated in \fBps\fR(1) output. In \fBps\fR output, you will observe two \fBsendmail\fR invocations, such as the ones below: |
|
49 .sp |
|
50 .in +2 |
|
51 .nf |
|
52 /usr/lib/sendmail -Ac -q15m |
|
53 /usr/lib/sendmail -bd -q15m |
|
54 .fi |
|
55 .in -2 |
|

|
57 .sp |
|
58 .LP |
|
59 The first indicates the use of \fBsubmit.cf\fR, with the client queue (\fB/var/spool/clientmqueue\fR) being checked\(emand, if needed, flushed\(emevery 15 minutes. The second invocation runs \fBsendmail\fR as a daemon, waiting for incoming SMTP connections. |
|
60 .sp |
|

|
62 As shipped, \fBsendmail.cf\fR and, in particular, \fBsubmit.cf\fR, are appropriate for most environments. Where a knowledgeable system administrator needs to make a change, he should use the following procedures. |

271 These properties persist across upgrades and patches. To prevent a patch or upgrade from clobbering your \fB\&.cf\fR file, or renaming it to \fB\&.cf.old\fR, you can set the desired properties instead. |
