Hello,Is there the username specification for email system? It seems most special characters like ".", "-", "+", "_", "#", "$" are permitted in the username part. And even [email protected] is right (like my sender account). So I was confused. Thanks.
Have you tryied the RFC that defines email addresses? (even the space in allowed: <my [email protected]> or "my name"@example.com)
