PostMinderSM
From the developer: "The online equivalent of certified postal mail, PostMinderSM notifies you when emails are opened, read and forwarded. Digital certificate technology verifies emails with timestamps and datestamps. And advanced features, such as virus protection and self-destructing email, ensure your total control." This is a subscription service - it is not free. The service apparently works even when the recipient has disabled return receipts.

If someone works in a government position, their government e-mail address is public information. If you know the school a person attends, most schools have online directories. For graduates, there are often alumni directories.
