VPS Mail Bagging and Email Continuity with continuous filtering provides a complete disaster recovery solution for our clients whose email backup requirements exceed Webservio’s shared mail bagging limits and for administrators who want to take full control of their email backup solution. The solution provides a virtual private server for mail bagging and an additional VPS for Email Continuity. The solution includes continuous anti-spam and virus filtering for multiple domains and more than 50 users. By protecting your organization's email communications during primary mail server uptime as well as downtime, you can tremendously decrease the load on your network. To illustrate the solution the diagram is divided into two parts.

Normal Email Server Connectivity

When your primary mail server is functioning properly, all messages flow from your correspondents through the Internet and through either Postini or Webservio's SpamWeeder Anti-spam and virus filtering systems. For more detailed information on each filtering service, please see the following articles:

Anti-Spam and Virus Filtering - Postini

After filtering, the emails are sent to your company's primary email server where they are delivered to the proper employee's inbox.

When you employees send messages, they are not filtered unless you have purchased our Postini Enterprise solution. Please view the following article for more detailed information regarding outbound filtering:

· No Email Server Connectivity

When your email server is down due to regularly scheduled maintenance, power outages, or any other problem, the messages coming to your email server will continue to flow through the Internet and filter through either Postini or Webservio's SpamWeeder systems.

Clean emails are then routed to our VPS mail bagging service where the original message is stored. As your connection with the mail bagging server is a virtual private connection, system administrators have complete access to the your organization's portion of the server. System administrators may view and flush the email queue, view and delete messages, and add multiple domains names to be protected.

If the message recipient has an Email Continuity account configured, a “working copy” of the message is created and sent to the recipient's Email Continuity inbox. Your employees who are configured within the Email Continuity system may login and continue to send and receive web-based emails, or employees can pull the “working copies” via POP3 into office workstations.

When sending emails from the Email Continuity accounts, your correspondents will view the emails as having been sent from your domain name, and not a Webservio domain. In addition, sent messages will also be copied to the VPS Mail Bagging service. This allows a complete email history to be delivered to your primary mail server when it becomes available.

When your email server is back online, all original bagged messages and copies of messages sent from the Email Continuity accounts are delivered. Your mail server then distributes the messages to the proper employee's inbox.

As the name suggests, this service provides Virtual Private Server environments for both the Mail Bagging and Email Continuity services. This solution provides administrators with more control over bagged emails, is easily scalable, and much more efficient and robust. As a result, additional storage space can be quickly added, and bagged messages can be flushed on demand. In addition, the VPS Email Continuity system can be configured to maintain a history of emails for your employees to reference during primary mail server downtime.
