The Antair spam filter has problems on the 9000 Bold. When good mail is recovered from the spam box it is treated as unopened and the unopened register, shown beside the email inbox name, just keeps accumulating. Opening emails in the inbox makes no difference, nor does deleting. The only way to remove these values in the unopened register is to do a hard reset. I have had exchange of emails with Antair support and they agree that there is a problem and their engineers are working on it.
