How do I change the header font & size when creating new messages?
You don't get to edit the headers. Some are added by your e-mail client
when it sends your e-mail. Others are added by the mail server AFTER you
have sent it (i.e., you're not in control of your e-mail anymore after the
mail server accepts it). E-mail headers are NOT to be fonted or stylized.
They are just plain ASCII characters so *all* e-mail clients and servers can
understand them.
