&lt;br /&gt;
==Description==&lt;br /&gt;
&lt;br /&gt;
Through neglect an administrator may allow a domain name or e-mail account to expire.  Domains have a significant grace period for expiration, and e-mail addresses using free services such as Yahoo may expire after several months of not logging in.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Risk Factors==&lt;br /&gt;
&lt;br /&gt;
* The biggest risk involved is if you have an e-mail server on a domain that is allowed to expire.  The more users there are, the more personal information you are putting at risk when they use those e-mails as backup e-mails for accounts on websites.  An attacker can simply purchase the domain and setup a mailserver.  By analyzing the spam coming in, they can determine the actual usernames people used on the domain and possibly what services they used with those e-mails.&lt;br /&gt;
* Considering that, you should be careful only to use e-mails hosted on domains owned by companies that don't show any sign of going under in the future.&lt;br /&gt;
* There is very little recourse if a malicious entity has purchased your domain.  They can sell it back to you for however much money they want to charge.  Even if you have grounds for a lawsuit, it can take months at least.&lt;br /&gt;
* If you have applications(especially no-longer supported) sending data to a domain, if an attacker buys the domain they can gather personal information from your users.&lt;br /&gt;
* Domains most likely to expire are those belonging to projects or companies that no longer exist.&lt;/div&gt;</summary>
