To allow the Cisco ESA to encrypt an email using the CRES (Cisco Registered Envelope Service), a provisioned email encryption profile must be configured on Cisco ESA. A provisioned email encryption profile is a type of encryption profile that specifies how messages are encrypted using CRES, such as the encryption key strength, the notification options, the branding settings, etc.

Content filters are rules that allow Cisco ESA to perform actions on messages based on predefined or custom conditions, such as headers, envelope, body, attachments, etc.

The two primary components of content filters are:

• Conditions, which are the criteria that determine whether a message matches a content filter rule or not, such as message size, sender address, attachment type, etc.
• Actions, which are the operations that Cisco ESA performs on a message if it matches the conditions of a content filter rule, such as deliver, drop, quarantine, encrypt, etc.

The other options are not primary components of content filters on Cisco ESA.

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.
