Why does Microsoft Outlook Express report a gateway error after installing Web Daemon ?
There is a potential conflict between the inter.net.works Web Daemon and outbound mail scan within some antivirus products. The recommended corrective action is to disable e-mail acceleration within the Web Daemon. The option to disable e-mail acceleration is located in the advanced tab of the Web Daemon options. As an alternative, you may choose to stop outbound mail scan within your antivirus product.
