CDO - It's how MS web servers send mail. It's built in to XP Pro but not
very
useful for an end user. If you press F3 while previewing (repeat
previewing not viewing) a message you'll see the headers include what
email/newsreader made it. If it comes from a MS web server or an
automated system on a MS server it will say CDO. Collabrative Data
Objects.
I'm from Louisiana. I hope I helped you. Good luck.
