If you check that box in your settings, you'll get a a PM (this is your receipt) whenever someone reads a PM you sent them. Its subject will be Read:[The subject of your PM], and it will have the date and time that the PM was read.

Oh, hah, sorry. Couldn't tell that from your first post. No, it will only work from now on. Every time you start to compose a new PM, near the bottom you should see the option for saving a copy to the Sent folder as well as the one for requesting a read receipt. Selecting those options in your profile automatically checks those boxes for future PMs, but doesn't affect old ones.
