pre_comment_author_email WordPress Filter Hook

The pre_comment_author_email hook is called before the comment author's email address is sanitized. This hook allows you to modify the comment author's email address before it is sanitized by WordPress. This can be useful if you want to allow users to enter their email address in a certain format, or if you want to make sure that all comment author email addresses are in a certain domain.
