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 <nick@domain.tld>. 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.
