But it's a valid approach in some scenarios. Don't expect everyone to guess what your particular scenario entails. You'll generally get better answers the more detail you give.
Bottom line is that you cannot control what the recipient sees when a message is addressed to them as a Bcc recipient. Their mail client application controls that.
Your company's policy pretty much guarantees that at least some of of the mail you send will be rejected as spam. I wonder why they chose such a policy.
