Cisco CCNP Security 350-701 Question # 417 Topic 42 Discussion

Explanation

Cisco Email Security Appliance (ESA) protects the email infrastructure and employees who use email at work

by filtering unsolicited and malicious email before it reaches the user. Cisco ESA easily integrates into existing

email infrastructures with a high degree of flexibility. It does this by acting as a Mail Transfer Agent (MTA) within

the email-delivery chain. Another name for an MTA is a mail relay.
