What are you trying to achieve or the steps to reproduce ?

I'd like to achieve using Joi's string email method to validate international email addresses. Currently an error is returned on international email addresses.

Describe your issue here, include schemas and inputs you are validating if needed.
Valid international emails, via wikipedia, are failing the Joi string email validator.

const Joi = require('joi');
console.log(JSON.stringify(Joi.validate('Dörte@Sörensen.example.com', Joi.string().email())));

Which result you had ?

{"error":{"isJoi":true,"name":"ValidationError","details":[{"message":""value" must be a valid email","path":"value","type":"string.email","context":{"value":"Dörte@Sörensen.example.com","key":"value"}}],"_object":"Dörte@Sörensen.example.com"},"value":"Dörte@Sörensen.example.com"}

What did you expect ?

No error in the response.
