A pedant that hangs out in the dark corner-cases of the web.

What happens when people don't know what they're doing: DoNotReply.com and RFC 2606

People without a basic understanding of RFC 2606 have been using a From or Reply-To address of donotreply@donotreply.com, and surprise!, that domain exists.

This implies not just job incompetence, but a manner so cavalier and naïve that the person responsible didn't even consider typing donotreply.com into a browser.

This is a level of technical malpractice worthy of termination, IMO.

Remember, the people that designed the Internet were generally pretty clever folks. If you need a phony domain name (akin to a 555 phone number), for example, there's a pretty good chance someone has set aside a few of those.

  • .test
  • .example
  • .invalid
  • .localhost
  • example.com
  • example.net
  • example.org

Note: IANA has even set aside an example MIME supertype and subtypes for all of the other supertypes.
