Is there a standard domain for testing "throwaway" email?

I started using [email protected] for this purpose, but then I began getting responses back from my outgoing email server saying delivery to that address had been delayed. I don't know about the OP, but I want something that I can send to and completely forget about it.

Now I'm changing over to [email protected] -- I know that it gets delivered to their catchall (so I'm not getting any junk back about delivery errors), and if I like, I can even go check at to see if the email went through as planned. (But it's not clogging up my inbox if I don't care about it.)

You can use According to the Wikipedia article:,, and are second-level domain names reserved by the Internet Engineering Task Force through RFC 2606, Section 3,1 for use in documentation and examples. They are not available for registration.

By implementing the reservation, the Internet Assigned Numbers Authority (IANA) made available domains to use in manuals and sample software configurations. Thus, documentation writers can be sure to select a domain name without creating naming conflicts if end-users try to use the sample configurations or examples verbatim.

When an address such as "[email protected]" is used to demonstrate the sign-up process on a website, it indicates to the user they should fill in an actual e-mail address at which they receive mail. "" is used in a generic and vendor-neutral manner.

These domain names resolve to a server managed by ICANN.
