Exchange deployment


MAILsweeper for Microsoft Exchange provides protection by intercepting and checking all mail messages as they arrive in each user's mailbox on the Exchange Server.

Mail that does not arrive in, or pass through a mailbox is not checked by MAILsweeper. This includes mail in public folders and in some cases outgoing mail passing out of the Exchange Server, to a user on an external mail system.

Outgoing external mail passing through Exchange Server's SMTP connector will be scanned because the SMTP connector employs a virtual mailbox. Mail is scanned as it arrives in this mailbox. Mail will also be scanned for other mail system connectors that use a similar method.

MAILsweeper for Exchange must be installed on the same machine as the Microsoft Exchange Server.

Microsoft Exchange Server can only run on a Microsoft Windows NT 4.0 Server.

MAILsweeper only supports Microsoft Exchange Server version 5.0 and above.

In a normal Exchange environment, when a user sends a mail message to another user the following happens:

1. The sender's Exchange client creates a record for the message in the Exchange Server's mail database.
2. The Exchange Server's router task moves the record to the recipients mailbox.
3. The recipient Exchange client reads the record from the mailbox.

After MAILsweeper installation the following happens:

1. The sender's Exchange client creates a record for the message in the Exchange Server's mail database.
2. The Exchange Server's router task moves the record to the recipients mailbox.
3. As the mail arrives in the mailbox the Exchange Server notifies MAILsweeper. If the message passes MAILsweeper validation it remains in the inbox folder to be read. Otherwise it is quarantined and does not appear in the inbox folder.
4. Assuming the mail was clean, the recipient's Exchange client reads the record from the mailbox database.

To deploy MAILsweeper for Exchange follow the steps outlined below:

1. Ensure that the Exchange Server machine has TCP/IP and RPC services installed and enabled. This machine should also meet the technical specifications and pre-requisites outlined on page 2-165.
 
2. Ensure that the Exchange client software is installed.

This is required because MAILsweeper logs on to the Exchange Server as an Exchange client.

Refer to your Exchange documentation for more details.
3. Load any anti-virus tools that you wish to use with MAILsweeper and note their locations. You will be asked for this information later, during installation.

Check the release notes to ensure compatibility between this release of MAILsweeper and the anti-virus tools you wish to use.

There are several evaluation copies of anti-virus tools supplied on the installation CD-ROM. Note that the set-up software does not automatically install these anti-virus tools.

4. Using the Exchange Administrator create a new mailbox called MAILsweeper on the Exchange Server. MAILsweeper notifications will appear to come from this mailbox.

Set the Primary Windows NT Account for the MAILsweeper mailbox to be the Windows NT account used by the Microsoft Exchange Server services.

See the Setting the logon account section on page 2-179 for more details.

5. Using the Mail and Fax icon found in the Control Panel, create a Profile called MAILsweeper. This profile must include Microsoft Exchange Server amongst its information services. The properties for this information service must specify the name of the Exchange Server and the name of the mailbox created in step 4., that is, MAILsweeper.
Refer to your Windows NT documentation for more details.
6. Shutdown the Exchange client and Server Administrator.
 
7. Install MAILsweeper for Exchange.

See the Installation section on page 2-166 for details.

8. Start MAILsweeper.
Refer to your Exchange documentation for more details.
