comment_notification_headers
Description
Applied to the mail headers before sending email notifying the post author of a new comment. Filter function arguments: mail header text, comment ID. Note that this happens inside the default wp_notify_postauthor function, which is a "pluggable" function, meaning that plugins can override it; see Plugin API).
