Aliases permit a number of things to happen:
|
||
|
<P>
|
||
|
<UL><LI>
|
||
|
They provide a shorthand or well-known name for mail to be addressed
|
||
|
to in order to go to one or more persons.<LI>
|
||
|
They invoke a program with the mail message as the input to the
|
||
|
program.<LI>
|
||
|
They send mail to a file.
|
||
|
</UL>
|
||
|
<P>

|
All systems require aliases for Postmaster and MAILER-DAEMON to
|
||
|
be RFC-compliant.
|
||
|
<P>
|
||
|
Always be extremely aware of security when defining aliases that invoke
|
||
|
programs or write to programs since sendmail generally runs setuid-root.
|
||
|
<P>
|
||
|
Changes to the aliases file do not take effect until the command
|
||
|
<P>
|
||
|
<P><P>
|
||
|
<P>
|
||
|
is executed to build the required dbm tables. This can also be done by
|
||
|
executing the newaliases command, usually from cron.
|
||
|
<P>
|
||
|
Details concerning mail aliases may be found in the aliases(5) manual
|
||
|
page.
