Bounce Verification is a feature that mitigates denial of service attacks on Cisco ESA. A denial of service attack is an attempt to overwhelm a system or network with excessive traffic or requests, rendering it unavailable or slow for legitimate users. Bounce Verification prevents Cisco ESA from accepting bounce messages that are not generated by it self or by trusted hosts, reducing the load on the system and preventing backscatter spam.

According to the [Cisco Secure Email User Guide], you can create a text resource of type Dis claimer Template and use the code view option to insert HTML code into the text box. Then, you can use this text resource in a content filter to prepend or append the HTML message to the email body[ 1 , p. 15-16].

The other options are not valid because:

A. Creating a text resource type of Disclaimer Template and pasting the HTML code into the text box without changing to code view will not work, as the HTML code will be treated as plain text and not rendered properly[ 1 , p. 15].

C. Creating a text resource ty pe of Notification Template and pasting the HTML code into the text box will not work, as Notification Templates are used for sending notifications to senders or recipients, not for modifying the email body[ 1 , p. 17].

D. Creating a text resource type of No tification Template and changing to code view to paste the HTML code into the text box will not work, as Notification Templates are used for sending notifications to senders or recipients, not for modifying the email body[ 1 , p. 17].

The global setting that is configured under Cisco ESA Scan Behavior is the actions for unscannable messages due to attachment type. This setting allows the administrator to specify what action to take when a message contains an attachment that cannot be scanned by the appliance, such as encrypted or password-protected files. The possible actions are:

Deliver - Deliver the message normally.

Drop - Drop the message silently without notifying the sender or recipient.

Quarantine - Quarantine the message in a specified policy quarantine.

Bounce - Bounce the message back to the sender with a specified reason.

To allow phishing simul-ations to bypass antispam scanning, the administrator must add two components to the allow list: domains and senders. Domains are the email domains that are used in the phishing simulations, such as example.com or test.com. Senders are the email addresses that are used to send the phishing simulations, such as phish@example.com or tes t@test.com. By adding these components to the allow list, the administrator can prevent them from being blocked by antispam scanning and allow them to reach the end users for testing purposes.  References : [Cisco Secure Email Gateway Administrator Guide - C reating Allow Lists]
