If you don't have an account, just leave the password field blank.
Well, it is true that you would need to have quite a bit of technical insight to pull it off properly, and so the common Joe or Jane wouldn't be able to do this, but there are scenarios where posing as somebody seriously could be harmful. For example, say you have a coworker who is extremely jealous at you for some reason. They could investigate into this matter, spoof a mail by you to your boss, a mail that would be sure to get you fired, and with nothing else than your own word of mouth to deny the authenticity of your mail, your boss may choose to believe your denial of the mail are just you having second thoughts, an act which may not be enough to save you your job...
