I think you need to some assistance with your setup, and a better understanding.
Sorry, read it too quick, thought I read "BES".
I thought it was odd that I got back a receipt from someone else last week with his private BB address (even though I didn't have his name), now it's not so unexpected.
And, no, I don't need assistance with my setup. It's been configured exactly as specified by RIM, and working exactly the way it should. However, I just did a little more testing and also have the solution.
Seems that the OS upgrade added some new email options we didn't have before. After the upgrade, RIM set the "confirm delivery" option on for all of my email accounts within the BB (messages-options-email settings). Although this is set within the device, it sets server-side options to send confirmations. Obviously it's a brain-dead decision to set this on for an email account that's intended to be private, and a rude surprise that RIM enabled it without warning.
I turned all receipts off for all accounts and everything's quiet now. Just for good measure, on one account I turned on all-singing delivery and read receipts and had receipts flying all over the place, but without revealing my private BB email address. Turned them off for that account and it's working the way it should.
The identity dump I observed earlier was RIM pre-setting my delivery receipt preference on the private BB email account, which then dumped the private email account identity to the sender who addressed a non-primary email address that was forwarded for push email.
For anyone else now joining this discussion, the recent 8703e OS upgrade requires that you review your email options within the device to confirm whether or not you want to be responding to any receipt requests. Obviously, most people will opt to turn them all off for the private email account, but, naturally, everyone's preferences are different.
