I have been trying to send an email with an attachment to a friend (have previously sent lots) and I keep getting a dropdown box saying that it could not be delivered due to "content policy reasons. It asks for me to check URLs , content and subject matter, which could be construed as Malware, Spam or Phising" Even an email with no text or attachment is rejected.
I have sent the same email to someone else and it is fine. So what is the problem please and how do I resolve it? Thanks.
