It did go to the blog, but, in the "Click here to listen to your message" link, the email contained the address of the blog, making it no longer private. It also contained the source email address and the email of the cc as well as the bcc email. So much for bcc!
So I have:
- Downloaded and saved the .wav message on the computer
- Edited this blog message - removing the reference to the link
- Attempted to upload the .wav message - COULDN'T DO - it only accepts images!
