Given its location, it may also be used by other email packages, but we are not currently aware of any.<br /> <br /> The actual filespec is defined by the &lt;code&gt;alias_maps = {{arg|filespec}}&lt;/code&gt;, with the default for {{arg|filespec}} being &lt;code&gt;hash:/etc/aliases&lt;/code&gt;. &quot;hash:&quot; therefore presumably means: &quot;This is the source file for generating the hash database file &lt;code&gt;{{arg|filespec}}.db&lt;/code&gt;&quot;.<br /> <br /> The file has a specific format which specifies a receiving address (the alias) and one or more destinations; these can be other addresses, user mailboxes, or files.<br /> <br /> By default, this file is only used when looking up email generated or forwarded internally; for email coming in from outside, Postfix uses the {{l/fn/abs|etc/postfix/virtual}} file, which is not as flexible.<br /> ==Notes==<br /> * Webmin seems to automatically run the [[newaliases]] utility when you add or modify an individual alias, but &#039;&#039;not&#039;&#039; when you use it to edit the &lt;code&gt;/etc/aliases&lt;/code&gt; file directly. Changes made to &lt;code&gt;/etc/aliases&lt;/code&gt; will not take effect until the database hash-file is updated.<br /> * Stopping and starting the postfix daemon does &#039;&#039;not&#039;&#039; update from the aliases file; you still have to run newaliases.<br /> ==Links==<br /> * [http://www.postfix.org/aliases.5.html Postfix documentation]</div> Woozle
