Bandwidth loading on the network is managed by pushing e-mail message traffic out to the edges of the network at times when bandwidth demand is low. To accomplish this, a user's e-mail is cached at the proxy server nearest to his presumed location. This decentralizes the e-mail storage away from the mail server and spreads it out over the network at the various proxy servers. This cache action is preferably done when there is a lull in network traffic (e.g., at night). This has the effect of decentralizing the bandwidth demand on the overall network since the e-mail messages have a shorter distance to travel when retrieved by the user from the cache location at the proxy server.
