There really is *NOT* a solution for this, unless you send the recipient a
unique token, and get them to click on a link that tells you they saw it.

Even that, somebody somewhere *could* write a script to fool you, unless
you also try to check that they are human when the click with one of those
warped text images.  Google for 'captcha'

Things that fail, and why/how:

Return-receipt:
The original plan was to have email clients return a receipt when an email
was opened.
Alas, privacy considerations, sheer volume of traffic, and people sending
them to lists of THOUSANDS of recipients made these completely useless.

Embed image with unique URL in HTML-enhanced (cough, cough) email:
Again, privacy concerns mean some people will force this to not work.
Plus, many email clients don't (or were configured not to) do HTML
enhanced email.
Security issues with HTML-enhanced email and privacy concerns killed it.

When you get right down to it, I guess the bottom line is always:

It's none of your damn business when/if I read your stupid email. :-)

About the only way to do that is to add a Return-Path header to the
e-mail so if it bounces the Return-Path address gets the bounce
message.

There is no way to do it more or less real-time because some SMTP
servers will try to send the message to the recipient for sometimes
five days before generating a bounce.

The mail() function allows you to specify additional headers that go into the 
mail.  Delivery acknowledgement is done using specific headers, the exact 
format of which I don't know off hand.  You will have to find the exact 
formatting information yourself, however this is the way to go.
