Every time someone I know sends me an email from his Gmail account it goes straight to the junk mail on icloud.com is there any way I can stop this He assures me he hasn't got any filters on.
Are you using PC or Mac? When in junk folder, can you right click the email and get options? On a Mac if you open your mail app and go to junk, highlight the email tap on the email with both fingers on trackpad and select the option.
