Description of Problem:

I would like to be able to specify acknowlegement
of the receipt of an e-mail. I want to know if
someone received a particularly important e-mail.
Netscape has this feature.

Steps to reproduce the problem:
1. Click on 'acknowledge receipt' and send e-mail
2. Send message has an icon beside it to indicate
that it has been received.
3. Click on this item to see details of who has
received it.

Actual Results:
Feature not available.

Expected Results:
As described above.

How often does this happen? 
Always. Feature not available yet.

Additional Information:
I have to admit, the latest Netscape/Mozilla is
looking quite enticing for e-mail. Also more
reliable. It's the calendar facilities and todo
list (and potential integration with MS Exchange)
that keeps me with Evolution for now.
