What did you see happen?
Email contains U+00D7 https://en.wikipedia.org/wiki/Multiplication_sign -> it is not an x-× Actual output : valid foo@bar.com× It is unquoted character and not allowed special character.
What did you expect to see?
Expected output: err should return with invalid email

net/mail specifies that it is RFC 5322 and extended by RFC 6532.
The preceding changes mean that the following constructs now allow UTF-8: ... 4. Domains.
Closing as working as intended.
