source
To keep ScanMail updated, you need to download the latest components. Use this page to set the source where ScanMail receives the latest components. The default location is the Trend Micro ActiveUpdate server. During manual or scheduled downloads, ScanMail checks the location you specify here, and downloads the latest components from that source.
A brief description of the options available on this screen is available below.
Trend Micro ActiveUpdate server: Select this option to download from the default update server.
Intranet location containing a copy of the current file: Select this option to download from an Intranet location.
Other Update Source: Select this option to specify an update source different from the default. The update source must begin with "http://".
Allow other servers to download updates from this server: Select this option to allow other ScanMail servers to download updates from this server.
The following lists the procedure required for configuring the download source.
To set the update source, select one of the following locations:
Trend Micro ActiveUpdate Server
Trend Micro uploads new components to the ActiveUpdate server as soon as they are available. Select the ActiveUpdate server as a source if you require frequent and timely updates.
Intranet location containing a copy of the current file
Download components from an Intranet source that receives updated components.
Type the Universal Naming Convention (UNC) path of another server on your network.
Note: Setting one or more centralized Intranet locations can greatly reduce network traffic and speed update time. This option is also useful when you do not want to connect an email server directly to the Internet. Instead, you can connect a front-end server to the Trend Micro ActiveUpdate server on the Internet and then set your back-end servers to receive updates from the front-end server.
Other update source
Download components from an Internet or other source.
You might choose to receive updates from a special server during testing. For example, when customers participate in Trend Micro beta testing, they type the name of the designated test server.
Allow other servers to download updates from a ScanMail server
Click Allow other servers to download updates from this server to set ScanMail to create a duplicate copy of the update package on the current server. Normally, ScanMail only downloads components that the user has set it to download or the increments of the components that it needs. When you set ScanMail to duplicate the update package, it will download all the components that are available for downloading.
For example: There are two Exchange servers (a and b) and each one has ScanMail installed. ScanMail is set up to update server "a" daily and download all components. ScanMail is set to update server "b" every week and download only the spam pattern component. Both servers receive updates from the Trend Micro ActiveUpdate server as required. Therefore, the components on these servers are not always identical and they require different incremental updates when they poll the ActiveUpdate server. Another, more efficient, way to configure your servers would be to set up server "a" to duplicate the update package. Then, you could set server "a" as the source for downloads for server "b", and server "b" could receive incremental updates from server "a" just as if server "a" was the ActiveUpdate server.
Note: You must duplicate the update package to clusters. That is, this option is grayed-out so that you must reproduce the components from one virtual server across all virtual servers on that node by default.
