Good day! I have a seriously problem. I don't understand why it's happens but only Microsoft mail services (outlook, hotmail, live) put the emails what is send from my mail server to the junk folder. I did a check with mxtools to see if there is something wrong with the mailserver setup, mailheaders or if we a listed on the spam blacklist somewhere in the world. But everything was fine. So what kind of things I can do check more?
