Is it possible to get proof an email has been read?

Yes

But only a crazy person would want that in his email client.
Imagine the email spambots getting data saying this or that message
had been read (sign of interest) or deleted unread (flagged as
uninterested).

I'd just ask the recipient to acknowledge he/she had received
it. Or even phone them, if it was important.

You could use the spam trick. Embed an image with an unique
URL in the body, and if the OP does not block loading images, you'd
get a hit when he/she opened the message.

e.g.

http://yourserver.com/john_doe/nice_cat222.png

Wouldn't stand up in court though.

I have no read receipt capability.

I can get proof I sent it by sending a BCC copy to myself.

Could you give more details on embedding an image with a url?

Thanks.
