OSX Mail how to mark message as not junk I have some mail messages that OSX Mail puts in my junk folder but does not show the header saying  "Mail thinks this message is Junk Mail" and so does not show the button allowing me to mark the mail as not junk.

How do I get Mail to allow me to mark the mail as not junk.

These emails are put in the junk folder by me.com/iCloud so I would hope Apple would allow control via their apps.
It seems iCloud is marking the message as junk using its algorithm. I don't believe you can adjust this from within the Mail.app. You will need to log into iCloud.com, enter Mail, find the particular message in your Junk Mail folder and then with the message selected, select the gear menu and you should be able to Mark as Not Junk.

To recap, as iCloud is flagging message as junk you must unflag message within iCloud.
