Introducing Symantec™ Mail Security for Microsoft®

Exchange

Symantec™ Mail Security for Microsoft® Exchange Server 2007/Server 2010 (Mail Security) provides a complete, customizable, and scalable solution that scans the emails that transit or reside on the Microsoft Exchange Server.

Mail Security protects your Exchange server from the following:

■ Threats (such as viruses, Trojan horses, worms, and denial-of-service attacks)

■ Security risks (such as adware and spyware)

■ Unwanted content

■ Unwanted file attachments

■ Unsolicited email messages (spam)

Mail Security also lets you manage the protection of one or more Exchange servers from a single console.

The Exchange environment is only one avenue by which a threat or a security risk can penetrate a network. For complete protection, ensure that you protect every computer and workstation by an antivirus solution.

What's new in Mail Security

Table 1 New and enhanced features Description Feature

Mail Security provides some predefined content filtering policy templates that you can use to create enhanced content filtering rules. These templates are a combination of match lists.

Content filtering policy templates

Mail Security provides the Quarantine entire

message and replace with text option for

processing the messages that trigger any policy rule violation. However, Mail Security does not support the Quarantine entire

message and replace with text action for

Auto-Protect, Manual, Scheduled, or Background scanning. If a violation is detected during these scans, Mail Security quarantines the message by parts although you specify the action as Quarantine entire

message and replace with text for a policy.

Quarantine entire message and replace with text

Mail Security 7.0 sends an email notification to an administrator when manual or scheduled scan failure occurs.

Mail Security 7.0 sends email notifications to an administrator 60, 30, and 10 days before expiration of Antivirus and Symantec Premium AntiSpam licenses. In earlier version of Mail Security, an administrator would receive an email notification from Mail Security only once i.e. 60 days before license expiration.

Enhancement in Alert and Notification

The manual or scheduled scan performance is improved with the implementation of multithreaded scanning. The scanning time that is required for manual or scheduled scan is now reduced.

Performance improvement in manual or scheduled scans

In Mail Security 7.0, you do not need to create multiple content filtering rules to scan different parts in a message. You can create a single content filtering rule to scan all message parts.

Enhancement in content filtering Getting Started

Table 1 New and enhanced features (continued) Description Feature

The content filtering performance is improved in terms of CPU utilization and the overall response time that is required to run the requested commands. This improvement is visible for all types of content scanning. Performance improvement in content

filtering

This feature is applicable only for Exchange Server 2013.

VSAPI is removed from Exchange Server 2013. Therefore, Mail Security provides an alternate solution for continuous protection in the form of a scheduled scan.

Continuous protection scheduled scan

Mail Security provides an advanced heuristics-based detection for enhanced antivirus effectiveness.

Advanced heuristics

Global Group consists of all the servers that are managed through Mail Security console. When you configure and apply Global Group settings, the changes are propagated to all the servers in all the groups. Changes that are made at the Global Group level overwrite group settings of all individual and user-defined servers.

Addition of a Global Group for Exchange Server 2013

Mail Security for Microsoft Exchange Management Pack

Before you install

Ensure that you meet all system requirements before you install Mail Security. Select the installation plan that best matches your organization's needs, and ensure that you have met the pre-installation requirements.

See“System requirements”on page 12. See“Installation options”on page 15.

Mail Security supports upgrades from Mail Security 6.x or later. If Mail Security detects an older version of the product on your computer, the installer

automatically uninstalls the prior version. The installer then continues with the installation. If you want to uninstall the previous version manually, do so before installing the current version of Mail Security.

If you want to install Mail Security on Exchange Server 2007/2010, then install the product on all of the following server roles in your organization:

■ Edge Transport servers, if available

■ Hub Transport servers

■ Mailbox servers

If you want to install Mail Security on Exchange Server 2013, then install the product on Mailbox servers in your organization.

You must uninstall and reinstall the product if you change the server role on which Mail Security is installed.

Mail Security automatically installs custom transport agents when you install the product on Hub Transport or Edge Transport servers. The Mail Security transport agents consist of an antispam transport agent and an antivirus transport agent. By default, the Mail Security transport agents are installed with a lower priority than the Exchange transport agents. If you modify your transport agent priorities, ensure that the Mail Security transport agents remain a lower priority than the Exchange transport agents.

Do the following before you install the product:

■ If you are running Symantec Brightmail™ AntiSpam on the same server on which you want to install Mail Security, you must uninstall Symantec Brightmail AntiSpam before you install Mail Security. It is recommended that you not run Mail Security on the same server as Symantec Brightmail AntiSpam.

■ If you are using the email tools feature of Symantec AntiVirus™ Corporate Edition, you must uninstall the feature before you install Mail Security. The email tools feature of Symantec AntiVirus™ is not compatible with Mail Security or Microsoft Exchange.

■ If you are running any antivirus software that is on the server on which you want to install Mail Security, you must disable it before you install Mail Security.

After installation but before you re-enable the antivirus protection, configure your other antivirus programs to exclude certain folders from scanning.

■ Log on as a Windows domain administrator to install Mail Security components correctly.

■ Modify your screen resolution to a minimum of 1024 x 768. Mail Security does not support a resolution less than 1024 x 768.

■ Configure the default receive connector for the Exchange Hub Transport server to permit connections from anonymous users.

Before you install Mail Security on Exchange 2010 mailbox role, you must specify a domain user account. The domain user account must fulfill the following criteria.

■ Mail Security uses the domain user account as a service account and this account must have a mailbox.

■ The user must be a member of Organization Management group under the Microsoft Exchange Security Groups Organizational Unit.

■ By default, Organization Management group is a member of the local

Administrators group on all the exchange servers in the organization. If not,

then add the user to the local Administrators group.

■ You may use different user account for installations of Mail Security on other Exchange 2010 mailbox servers within that domain for better performance.

■ When the user updates the password, the same password must be provided to the Mail Security Service on all Exchange 2010 mailbox role servers.

Note:While installing Mail Security on local Exchange 2010/2013 Mailbox server, in the Logon Information screen, specify the domain user credentials in the User

name and Password fields. Mail Security provides this user account Application Impersonation and Logon as service rights.

Ensure that the following IIS Role Service components are installed when you install Mail Security on Windows Server 2008. This installation is applicable for both remote and local installation.

■ Application Development - ASP.NET

■ Security - Windows Authentication

■ Management Tools - IIS management console , IIS 6 Scripting Tools

System requirements

Ensure that you meet the appropriate system requirements for the type of installation that you are performing.

If you do not have Internet connection on your system, then installing Mail Security may take a long time to complete. Mail Security tries to examine the certificate revocation list (CRL) to verify the code signing certificate each time that Mail Security compiles an assembly into managed code. When Mail Security is not connected to the Internet, each CRL request may time out before the installation can continue and increases the installation time.
