How can an admin review and modify buddypress private messages before being received by recipients?

Hi,

I need a way for an admin to be able to screen private messages sent in buddypress. After a user sends a private message in buddypress, I need the admin to be able to check the message for any and all contact or personal information such as the senders name, email address, phone number, etc., or any information that would allow a user to identify and/or contact another user outside of my buddypress community website. After the admin checks, and if necessary, removes contact information, the admin can approve the message to be received by it’s intended recipient. Can you recommend a plugin or some other way that would help me achieve this? Maybe a system that would send private messages to the admin first and allow the admin to extract contact information before clicking something to allow the message to be received by it’s intended recipient?

Thank you in advance for any help that you can provide.
