I have three brand new iMacs with IMAP accounts on Mail which are taking matters into their own hands and marking unopened emails as read. They are not accidentally or otherwise selecting those messages. If you select the message second from top and then wait for more to come in, you can see the blue dots vanish without touching the computer at all. It doesn't happen to all messages and is happening to a number of accounts though all accounts are hosted by the same ISP.

 

I've never seen this issue. Any ideas?
