How not to validate email addresses

Also sometimes you don't even need the TLD:

user@myhostname, is a valid email address, and yet it's rejected by a lot of libraries.

It's certainly valid address, but why would you want to input that as an email address into public-facing service that you do not operate?

Perhaps I do operate it. Can be very useful on say a dev box.

Just because it's a valid address doesn't mean a real user is going to sign up for an account using a domain without a TLD.

Perhaps users are aware of relative domain names and addressing. You even see this on a service like gmail's login. A user with the address [email protected] doesn't have to enter '@gmail.com' when logging in - just 'example'. But actually either will do. Further it's not totally clear for a user what to enter here. Is a username/id is the same thing as an email address or not.

My aunt swears blind that an email address without the name in double quotes and the domainy bit is not a correct email address. She types the lot out.
