A computer readable medium includes executable instructions to insert partial authentication content into a message. The modified message is then delivered through an electronic network to a recipient. Upon receipt, the partial authentication content is processed without processing the entire message. This results in an authentication response indicative of the authenticity of the message. In some instances the message is partially authenticated and therefore delivered. In other instances, the message is not partially authenticated and various processing options are invoked, such as quarantining the message, modifying the message with a warning, modifying the message to remove content, and/or sending a message to a spoofed machine advising the spoofed machine of a spoofed message. The authentication operations of the invention may also be used in connection with the implicit content of the message.
