Sorry for the inconvenience. Please note we have recently added a very powerful global email filtering feature, which also blocks a lot of un-trusted email servers from sending spam emails to DriveHQ email addresses. There is a small possibility that the email filter blocks good emails. In this case, please send emails from other email address, such as hotmail, Yahoo or Gmail, etc. Please also provide the detailed email headers so that we can add your email server as trusted email server.
