Why all the info@mydomain.com emails go to spam folder even if that account is spam white-listed?

Hi. Since a week, all the email messages of our job distribution email account (info) are being sent to the spam folder, even though the account and the domain are white-listed for spam. That happens to all of our user accounts. Do you have any suggestion?

Thank you
