Email Protection Administrator Guide Differences in Administration for Service

November 2012 Proprietary: Not for use or disclosure outside McAfee without written permission 1

1. Overview

McAfee®Saas Email Protection provides security services that safeguard corporations

from unsolicited spam email (junk mail), viruses, worms, and unwanted content at the

network perimeter before they can enter the internal network.

Multiple layers of McAfee Saas Email Protection provide secure and complete email

filtering to protect your users. You can enable or disable specific layers by changing the

licensed packages of features and/or through configuring the specific email policies in the

Control Console, the comprehensive graphical interface into McAfee Saas Email

Protection.

This document describes the tasks necessary to configure and maintain your McAfee Saas

Email Protection.

Differences in Administration for

Service Providers

This document is for use by Enterprise customers only. Service Provider customers do not

administer groups for Email Protection and therefore, do not assign groups to email

filtering policies. Instead, Service Provider customers assign policies directly to domains.

The capabilities for managing policies and groups, as described in this document, apply

only to Enterprise customers.

Account Management Necessary for

Email Protection

Account Management is a set of administrative windows you use to configure and manage

the entities that use or are affected by Email Protection (Email Protection), as well as the

Web Protection Service (WDS) and Message Archiving products. These entities include:

• Domains

•Users

• Other administrators, including other Customer Administrators, Domain

Administrators, Quarantine Managers, and Reports Managers

In addition, for Email Protection only, you use Account Management to administer groups

of users that share a common email filtering policy.

For more information, see Account Management Administrator Guide.

Auto-creation of Users Email Protection Administrator Guide

2 Proprietary: Not for use or disclosure outside McAfee without written permission. November 2012

MX Record Validation

You can validate that the MX Records that are configured for your domain are properly

redirected by entering the specific DNS and/or IP address for your MTA server. The

Control Console displays the MX Record configuration as reported by the authoritative

DNS server.

See Check Your MX Record.

Alias Domain Names

You can configure alias domain names that act as virtual domains using the configurations

and email addresses defined in the primary Domain name. Email addresses are created

automatically for alias domains (for example, [email protected] is

automatically created for jsmith@yourcompany.com), allowing the single user to receive

email for both addresses.

For more information, see Account Management Administrator Guide.

Auto-creation of Users

The Email Protection automatically creates new user accounts if all the following is true:

• SMTP Discovery is enabled. SMTP Discovery, which is enabled by default, is a

convenient way to add users to your service. However, this capability might also add

users who are not real users at your company and not add users who are real.

• SMTP discovery creates users that receive eight valid emails within a 24 hour period.

• A user account does not exist for the email address in the designated Domain.

• The emails were not addressed to an alias domain name.

For more information, see Set up User Creation Mode — SMTP Discovery or Explicit.

Email Filtering Policies

Email Protection has default inbound and outbound mail filters to block and clean

malicious email and to quarantine email that might be malicious. The filters are

configured by using policies, which are the parameters for the filters default policies are

automatically assigned to each of your domains.

You can customize the default inbound policy for any and each domain, or any and each

group, to fit your business Email Protection.

For more information, see Customize Inbound Mail Filters.
