another one of those badly worded answers

C - Configuring the Content Vector Protocol (CVP) resource to forward the mail to the internal SMTP server, without waiting for a response from the Security Gateway

because it says that the data is forward straight to the internal SMTP server, rather than the security server first - from the pdf the correct action is to pass it to the security server firstly even though the packets have not been checked and then on to the SMTP server.

Thanks again for your help.
