In the past week emails from one of my friends started going into junk mail. The person in in my contacts. I selected 'enable adaptive emailjunk mail..." and selected the correct address book. The mail still went to the junk folder. I changed the 'move new junk mail to: my inbox, still went into the junk folder. I had him send me 10 emails that I marked as 'not junk' still no success. My emails come from yahoo.com - went there and there was nothing in the spam or junk folder in my yahoo email account. This is happening to only one email address. There's nothing strange in the title of the email or the content. I've run out of ideas.
