The present invention is directed to a system and method for providing the secure exchange of messages utilizing an existing unsecured messaging network such as the Internet. A messaging proxy is provided between a sender of a message and the unsecured messaging network. In sending a secure message, the messaging proxy contacts a key exchange server via an authenticated secure connection. The messaging proxy generates a key with which to encrypt the message. The key is sent via an authenticated secure connection to a messaging proxy of a recipient. If the sender receives an acknowledgement of the recipient receiving the key, the message is encrypted and sent via the unsecured messaging network. The recipient then uses the key to decrypt the message. Should the recipient not have a proxy in place to receive encrypted messages and a corresponding key exchange server, the message is sent unencrypted.

A system and method automatically rescales an electronic message having one or more associated content. When the electronic message is generated and the associated content connected to the message, an agent of the electronic message application checks predefined settings / configurations of the message client. The sender's e-mail client checks a plurality of conditions, such as, the condition of the network, the type of network, the status or capacity of the receiving inbox of an intended recipient client, and the geographic destination of the message. Based on these dynamic content rescale settings, the sender's client dynamically and optimally rescales the associated content before forwarding the electronic message with the rescaled content to the recipient client. Rescaling of the associated content may be performed by the message exchange server or the recipient client. The recipient client may later request and receive a copy of the associated content without rescaling.

A server has a firewall module that performs accounting of traffic seen at the server. The traffic includes message exchanges, such as HTTP requests and HTTP responses. The server tests the message exchanges to determine if they match any of several message exchange categories. The server keeps statistics on matching traffic, for example the rate of matching traffic generated by a particular requesting client. Typically, the server is a proxy server that is part of a content delivery network (CDN), and the message exchanges occur between a client requesting content, the proxy server, other servers in the CDN, and / or an origin server from which the proxy server retrieves requested content. Using the message exchange model and the statistics generated thereby, the server can flag particular traffic or clients, and take protective action (e.g., deny, alert). In an alternate embodiment, a central control system gathers statistics from multiple servers for analysis.
