A friend and ex co-worker of mine, at our first job, had to write some code to send emails. Not knowing any better, he ran his manual tests using a clearly non existent email address, just a combination of letters. Or, so he thought: he soon received an email from said combination of letters, begging him to please stop spamming.

I thought the TLD test was meant for this, like mydomain.test.

According to RFC 2606:

> ".example" is recommended for use in documentation or as examples.

Using example.[com|org] for testing feels like shoehorning. I wish IANA had reserved test.com, because that's what feels right when testing.

Surely example.com has these problems too, although to be fair they don't really need to receive any email.
