In-house MS Exchange Server and SonicWALL Anti-Spam Desktop
In this scenario, e-mail is received from the Internet and each user connects to the in-house e-mail MS Exchange e-mail server (Figure 1). E-mail is downloaded to the Outlook or Outlook Express client on a regular basis and is filtered for spam and phishing by SonicWALL Anti-Spam Desktop. There is no requirement for the E-mail Server to reside in-house as long as the client can "reach" the server to retrieve e-mail. Alternately, the Outlook or Outlook Express Client may use POP or IMAP to pull down received e-mail from a separate e-mail server.

Hosted E-mail and SonicWALL Anti-Spam Desktop
For many organisations, an ISP or E-mail Hosting company receives the e-mail and stores it until it is accessed by individual users. In this scenario, Anti-Spam Desktop can be deployed to protect Outlook or Outlook Express clients accessed via POP (but not e-mail accessed by the client via HTTP or HTTPS).

SonicWALL Email Security and SonicWALL Anti-Spam Desktop
Should Anti-Spam Desktop detect an upstream SonicWALL Email Security device, it will display a Web Settings menu on the Toolbar (Figure 3).

In this scenario (Figure 4), Allowed and Block List information is copied upstream from SonicWALL Anti-Spam Desktop to SonicWALL Email Security. In this configuration each user will have two Junk Mail boxes: one on the Email Security system and one on their Desktop client.
