tc,
re: "spoofed email address"
Yep, that is what i thought, too. I rebuilt my Outlook email account, making some subtle changes to the mail account name and reentering all the other information as it was before.
It seems to have done the trick. I haven't gotten one of those messages from postmaster@msn.com for a couple of days.
Being an engineer, I would really like to know how this happened in the first place, but I guess I'll never know.
