No, it's the server's job. The MUA sets the Bcc header, the MTA deals with =
it.
A server that reveals the Bcc header to any recipient is a broken server.

The 'B' stands for 'blind', it's called blind for a reason.

There's no mystery to this, it's really simple to grasp, no recipient should
see the Bcc header or its contents.
