This PR fixes the issue where adding an alternative email address with an internationalized domain name (IDN) containing the ß character (e.g., test@dießner.de) failed. The validation logic incorrectly rejected such addresses, preventing users from adding valid existing emails.
Changes:
Updated email validation to correctly handle IDN domains, including special characters like ß.
Ensured compatibility with internationalized domain names as per IDN standards.
Improved error handling so valid addresses are accepted without false rejection.
