|

23 | the <filename>main.cf</filename> and the <filename>master.cf</filename>
|
---|
24 | must be personalized for your system. The <filename>aliases</filename> file
|
---|
25 | needs your non-root login identity so mail addressed to root can be forwarded
|
---|
26 | to you at the user level. The <filename>main.cf</filename> file needs your
|
---|
27 | fully qualified hostname. All of these edits can be done with sed commands
|
---|
28 | entered into the console with appropriate substitutions of your non-root
|
---|
29 | login name for <replaceable>[user]</replaceable> and your fully qualified
|
---|
30 | hostname for <replaceable>[localhost.localdomain]</replaceable>. You will
|
---|
31 | find the <filename>main.cf</filename> file
|

32 | is self documenting, so load it into your editor to make the changes you need
