Emails: Unicode UTF-8

Hi

Don't know if anyone can resolve this puzzle for me.

Back in June my wife sent three emails (to two different people). She's not sure if they ever replied (so can't be sure they ever arrived).

Anyhow, all three turned up back in her Outlook Express Inbox yesterday at exactly the same time. They claimed to be from her to herself (rather than just returned as 'undeliverable') and were all headed UNICODE UTF-8.

They each contained the message to which she'd replied so, on the face of it, it looks as if she originally hit the 'Reply' button, so that the correct address would have been used. (As opposed to sending them to herself - which, I know, is always possible.)

But even if that were not the case, does anyone know why four months would pass and then they'd come back like this - and in what looks like a very odd way?

Just curious!
