Configuring Cisco Email Security Appliance

1.  Configure DNS entries

2.  Deploy Cisco ESA

3.  Complete the GUI-based system setup

4.  Install system updates and feature keys

Process

Before you begin the Cisco ESA deployment, you need to configure the 
DNS.

Procedure 1 

Configure DNS entries

Prepare for the following configuration procedures by creating the DNS 
records that are required for email communication. The DNS address (A) 
record provides a Fully Qualified Domain Name (FQDN) to IP addressing 
mapping and the DNS pointer record (PTR) provides an IP to FQDN map-
ping, also known as a reverse lookup.

Configure your internal DNS server to advertise the records listed in Table 4.
