<header>Alias To</header>

Each alias may redirect mail to several recipients, and each recipient
may be one of the following :
<dl>
<dt><b>Email Address</b>
<dd>Either a full email address like <tt>foo@bar.com</tt>, or the name of
    another user on your system like <tt>jcameron</tt>.
<dt><b>Addresses in File</b>
<dd>For this kind of alias you must specify the full path to a file
    containing a list of email addresses, one per line. Each address can
    be either fully qualified, or the name of another user on your system.
<dt><b>Write to File</b>
<dd>In this case, email will be written to the specified file. To have all
    email to some address thrown away, give <tt>/dev/null</tt> as the filename.
<dt><b>Feed to Program</b>
<dd>Each time an email message arrives for this alias, the specified program
    will be executed and the entire email message (headers and body) passed
    to it on the standard input.
