Whether for simple aesthetics, or because many of the sites that unnecessarily force you to register block known Mailinator domains, you may want your own disposable email domain.

For a start, you need to have your own domain. Don't want to use a paid one?  Never fear, freedns.afraid.org has you covered. Primero, you have to create an account… but it's for a good cause, and then register a subdomain in your more than ninety thousand domains, from to staples:

  1. Find one you like and click on its name (for example, spam-o-matic.com).
  2. Change Type a MX (mail registration).
  3. Enter the subdomain name you want inSubdomain (something like “protectedby” to get protectedby.spam-o-matic.com).
  4. Writes 10:mail.mailinator.com in Destination.
  5. List, you can receive emails immediately with any username (XXXX@protectedby.spam-o-matic.com), using that same username to check it out on mailinator.com

Of course we would save all this (and more) if everyone used OpenID.

P.S.d.P. (in passing): You can create free domains for your website in the same way., either by IP address (changing Type a A), aliasing an existing domain (Type CNAME), or doing a redirect to an address (URL) specific (creates a record A or CNAME, save it, edit it and clickForward to a URL.
