Is there anyway to set up outgoing mail as BCC

I wanted to know if there was anyway to permanently set up outgoing mail as BCC instead of the To   The to always comes up first and I forget to use the BCC but it is difficult when sending out forward mail and you are forwarding to many on your list  All their emails show up for spamers  to pick up so it is good to always use BCC so it is more private is there any way to change the To to permanently bringing up the BCC line so all mail goes out on the blind side.
