I have had this post for a month or so with no replies. Trying here with a different subject. I have a problem with about 50 messages that keep reappearing in the junk mailbox after I delete them and empty the trash. Within seconds, they reappear as junk. Some as new as yesterday, some dated back in January 2014. I have deleted the Junk mailbox and then hit rebuild. As soon as i finish the click, the messages reappear. I've done it 5 times, and then hit rebuild three times - still get the messages back. I've checked with my gmail account and the messages do not appear as spam or junk on my gmail account. Can anyone help me get rid of these old messages - permanently?
