Hi,

I have a new task to configure Postfix to implement a IPR related
policy. It is required that certain users should not be allowed to
email source code/documentation etc from the organization to external
recipients unless and until the recipient is an authorised recipient
possibly listed in a list for that particular user.

Its a little complicated and am not sure if it can be done. If it
cannot be done, is it possible to prevent internal users from sending
attachments to external recipients, but allow them to send attachments
internally while allowing only certain users to send attachments
outside the organization.

Thanks in advance,
Nitin

Ps. If anyone has best practices on email management to prevent IPR
leakages, please share with me.
