The default mail app on Android 4 seems to generate incorrect Read Receipts. Here is the case:
User ORIGINATOR sends email (using any mail client software), with request for Read Receipt (SMTP header Disposition-Notification-To), TO: PRIMARY-RECEIVER with CC: SECONDARY-RECEIVER.
When PRIMARY-RECEIVER opens the email, his email client will (optionally) send a Read Receipt which is FROM: PRIMARY-RECEIVER TO: ORIGINATOR.
When SECONDARY-RECEIVER opens the email, his email client should (optionally) send a Read Receipt which is FROM: SECONDARY-RECEIVER TO: ORIGINATOR.
But if SECONDARY-RECEIVER opens the email on Android 4 (Galaxy S3 in my tests), using the default email client, the phone sends a Read Receipt which is FROM: PRIMARY-RECEIVER TO: ORIGINATOR, which is grossly incorrect.
Has anyone detected the same issue?
Anyone has a suggestion on proper forum or support channel for reporting this bug?
