I have el capitan 10.11.2. I am using Mail 9.2. on the bottom left of mail I am seeing "downloading messages" (at this time 42 messages). I am assuming these are Junk Mail as I seem to getting valid e-mails in the normal way. However whatever these emails are they are not showing up anywhere. The JUNK mailbox has a X on the icon and theres is nothing there. on mail box preferences JUMK is showing Store on server (ticked) and Delete Never. on mail preferences I have enabled Junk Mail filtering etc. However I cannot see these messages anywhere. Although I most certainly do not want junk mail I am curious as to what these message are? nothing in Trash either relating to messages I don't know about. Any ideas?
