The altsrchost command enables an engineer to deliver a flagged message to a specific virtual gateway address in the most flexible way. This command allows you to specify an alternate source host for messages that match a message filter. You can use this command to route messages to different virtual gateways based on the message content or attributes.

Determining Which Interface is Used for Mail Delivery Unless you specify the output interface via the deliveryconfig command or via a message filter ( alt-src-host ), or through the use of a virtual gateway, the output interface is selected by the AsyncOS routing table. https://www.cisco.com/c/en/us/td/docs/security/esa/esa11-1/user_guide/b_ESA_Admin_Guide_11_1/b_ESA_Admin_Guide_chapter_011001.html?bookSearch=true

Secure unsubscribe option for end users. Mimicking an unsubscribe option is a popular phishing technique. For this reason, the end users are generally wary of clicking unknown unsubscribe links. For such scenarios, the cloud-based Unsubscribe Service extracts the original unsubscribe URI, checks the reputation of the URI, and then performs the unsubscribe process on behalf of the end user. This protects end users from malicious threats masquerading as unsubscribe links. https://www.cisco.com/c/en/us/td/docs/security/esa/esa14-2-1/User_Guide/b_ESA_Admin_Guide_14-2-1/b_ESA_Admin_Guide_12_1_chapter_01110.html#id_101033

External spam quarantine is a feature that allows Cisco SMA to store and manage spam messages quarantined by multiple Cisco ESAs in one central location, providing a unified view and administration of the spam quarantine data.

A filter is a method that enables an engineer to deliver a flagged message to a specific virtual gateway address in the most flexible way. A filter is a rule that allows Cisco ESA to perform actions on messages based on predefined or custom conditions, such as headers, envelope, body, attachments, etc.

To deliver a flagged message to a specific virtual gateway address using a filter, the engineer can create a content filter or message filter that matches the flag condition and applies an action of “deliver via alternate host” with the virtual gateway address as the parameter.

The other options are not methods that enable an engineer to deliver a flagged message to a specific virtual gateway address in the most flexible way, because they have more limitations or requirements than using a filter.

The safelist is a list of email addresses or domains that are considered legitimate and trustworthy by Cisco ESA. When an email is received from a sender on the safelist, Cisco ESA skips antispam scanning for that message and delivers it to the recipient without any spam filtering.

References: User Guide for AsyncOS 15.0 for Cisco Secure Email Gateway, page 6-13.

The safelist/blocklist (SLBL) is a feature that allows Cisco ESA to accept or reject messages from specific email addresses or domains, based on the configuration of mail flow policies or end user preferences.

The action that provides direct access to view the SLBL on Cisco ESA is to export the SLBL to a .csv file, which can be done from the web user interface by selecting Security Services > Safelist/Blocklist and clicking Export.

The other options do not provide direct access to view the SLBL on Cisco ESA.

ceo@example.com is the data that must be added to the dictionary to accomplish this goal. A content dictionary is a list of values that can be used as a condition in a content filter or a message filter. Forged Email Detection is a feature that allows Cisco ESA to detect and prevent email spoofing attacks, where the sender’s address or domain is forged to appear as someone else, such as the CEO of the organization.

To create a content dictionary for use with Forged Email Detection on Cisco ESA, the administrator can follow these steps:

• Select Mail Policies > Content Dictionaries and click Add Dictionary.
• Enter a name and description for the content dictionary, such as CEO Email.
• Under Dictionary Values, click Add Value.
• Enter the email address of the CEO, such as ceo@example.com.
• Click Submit.

The default port to deliver emails from the Cisco ESA to the Cisco SMA using the centralized Spam Quarantine is 6025. This is the default value for the Port setting in the External Spam Quarantine configuration on Cisco ESA. This port must be open on both Cisco ESA and Cisco SMA for the communication to work.

According to the [Cisco Secure Email Encryption Service Add-In User Guide], you can create an encryption profile that defines the encryption settings and options for your encrypted messages[2, p. 11]. You can also create an outgoing content filter that applies the encryption profile to the messages that match certain conditions, such as having [SECURE] in the subject header[2, p. 12]. This way, you can allow users to flag the messages that require encryption by adding [SECURE] to the subject line.

The other options are not valid because:

• A. Creating an encryption profile with [SECURE] in the Subject setting and enabling encryption on the mail flow policy will not work, as the Subject setting in the encryption profile is used to specify the subject line of the encrypted message envelope, not the original message[2, p. 11].
• B. Creating an outgoing content filter with no conditions and with the Encrypt and Deliver Now action configured with [SECURE] in the Subject setting will not work, as this will encrypt all outgoing messages regardless of whether they have [SECURE] in the subject line or not[2, p. 12].
• D. Creating a DLP policy manager message action with encryption enabled and applying it to active DLP policies for outgoing mail will not work, as this will encrypt messages based on DLP rules that detect sensitive data in the message content, not based on user flags in the subject line.
