BCC: field in system.net.sendEmail function

Title pretty much says it all!
When I send an email (usually containing a production report or similar) it would be handy to have the BCC: field available for use. I would rather have everyone in the BCC: field and no one in the To: field. This would prevent people from being able to ::cringe:: hit the dreaded Reply to all button!
Thanks and keep up the good work guys!
