<h2>Aliases</h2>

<h3>Add a mail alias</h3>

<p>Aliases are email forwarders. An alias can forward email to a <a href="#" onclick="return show_panel('users')">mail user</a> or to any email address.</p>

<p>To use an alias or any address besides your own login username in outbound mail, the sending user must be included as a permitted sender for the alias.</p>
