FROM

Hi boulderbrian,

This Plugin does not manipulate anything with emails, other than the recipient list.

To modify the from value, you’ll want to take a look at the filters provided by core.

For wp_notify_postauthor():

$message_headers = apply_filters( 'comment_notification_headers',    $message_headers, $comment_id );

For wp_notify_moderator():

$message_headers = apply_filters( 'comment_moderation_headers',    $message_headers, $comment_id );
