special characters in email addresses called "invalid"

[James Heinrich]

Plesk doesn't allow email addresses with "special" characters. I know it's perhaps not a recommended practice, but most of the shifted numeral characters (!#$%^&*) are valid in email names. As such, I need to set up a redirect to *@example.com but Plesk won't let me because * doesn't validate in /javascript/chk.js.php :: function chk_mn(mail_name)
