It's worth knowing how to read the headers of emails in this
circumstance as it can give you vital information for knowing what is
going on.
Unfortunately, I don't. Attached below is one of the mail delivery
failure notices, which includes the headers of the original message.
But I don't understand what it all means. Perhaps you or someone else
out there can make some sense of it and advise me accordingly.
Remember, I never sent the original e-mail. I just got the delivery
failure notice.
