The unix mbox format uses the sequence ["F", "r", "o", "m", " "] as its indicator that a new mail has started. If you're not careful about escaping your stored mails, you can easily corrupt them by starting a body paragraph with the word "From".
How do you escape the word From? Well, that's up to the client! Be careful using different clients for a given mbox file!
