BCC address field..

Here's the way I discovered today to design my own mail form containing BCC field

Steps

1.) Create a new mail using Ctrl+N
2.) Tools -> Forms -> Design this form
3.) Use Mail fields in drop down which appears as a pop-up
4.) Drag and drop the Bcc field

and customise it as per your requirements
