If you don't have an account, just leave the password field blank.
an email isnt just the text you see and/or html you input into the message. as simeon said, there is smtp. emails have a lot of 'junk' at the begging about whom the mail was from, the server they used, the time it was sent/recieved etc. so if someone could edit that smtp stuff at the beggining of an email i salute you (if you dont know what i mean go into outlook express and open up the emails's properties menu by right clicking. then click view message scource or something. dont know about other mail apps)
