I am tired of deleting "Delivered:" messages from my sent BCC: box every day.
I set up my BB e-mail settings not to confirm delivery or read receipts, but I still see that they are being sent.

Message like:
Subject: Delivered: RE: XXXXXX
Your message was delivered to the recipient.

with attachment including
Original-Message-ID:15XXXXXX
Final-Recipient:XXX@XXXX.com
Action:Delivered

Is this a bug?
