re: Properly validating e-mail addresses VIEW POST

FULL DISCUSSION
 

Whether Unicode is allowed in the name part rather depends on whether the SMTP servers involved support the SMTPUTF8 extension. In my experience they mostly don't. AWS's SES and Sendgrid don't for example.

 

That's not the problem of the validator though...

 

Well it is if you are letting through addresses your own SMTP server doesn't support.
