This solution provides a complete disaster recovery solution for a small to medium-sized business and is very cost effective. The solution includes continuous anti-spam and virus filtering for one domain and up to 50 users. By protecting your organization's email communications during primary mail server uptime as well as downtime, you can substantially 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 & Virus Filtering - SpamWeeder

Anti-Spam & 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 shared mail bagging service where the original message is stored. You may purchase an optional web-based interface access to view and/or flush the queue on demand as opposed to waiting for the automated delivery attempt cycle. This access allows system administrators to verify service functionality and provides peace-of-mind.

If the message recipient has an email continuity account configured, a “working copy” of the message is created and sent to the recipient's Shared Email Continuity inbox. Your employees who are configured within the Shared 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 and continue to send and receive emails.

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 Shared 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 is shared among many Webservio mail bagging and email continuity customers. While this is a very cost effective service, the caveats of any shared environment do apply. If extreme efficiency is a must, please view our VPS-based solution.
