<header>Mail Aliases</header>

The aliases provide a system-wide mechanism to redirect mail for local
recipients.

<p>

The <tt>Alias to...</tt> field contains one or more of the following,
comma-separated:

<ul><li><tt>address</tt>: Mail is forwarded to <tt>address</tt>, which is compatible
with the RFC 822 standard.

<li><tt>/file/name</tt>: Mail is appended to <tt>/file/name</tt>. See
local(8) for details of delivery to file. Delivery is not limited to regular
files. For example, to dispose of unwanted mail, deflect it to
<tt>/dev/null</tt>.

<li><tt>|command</tt>: Mail is piped into <tt>command</tt>. Commands that
contain special characters, such as whitespace, should be enclosed between
double quotes. See local(8) for details of delivery to command.
When the command fails, a limited amount of command output is mailed back to
the sender.

<li><tt>:include:/file/name</tt>: Mail is sent to the destinations listed
in the named file. Lines in <tt>:include:</tt> files have the same syntax as
the right-hand side of alias entries.

</ul>
