How do I set Mail.app not to send the recipient names as they appear in my address book

When I send mails to addresses from my address book, the recipients in the address bar are shown like name <[email protected]>. Can I somehow prevent that name part, so that only the actual mail address is shown and not the names, as I name them in my personal address book? I kind of feel like it's not for the public how I name my contacts.

While composing and email you can click the arrow in the address and choose Edit Address or double-click the address to edit the information. By deleting the name and leaving just the email address (it should look something like < [email protected] >) should do the trick. I couldn't find a way of having this changes done permanently, though.
