This pipeline consists of several phases that the emails go through before they are delivered or rejected.
The two phases of the Cisco ESA email pipeline are:
Workqueue: This is the first phase in the pipeline, where incoming emails are received and processed. During this phase, the ESA performs a variety of checks on the email, such as checking the sender reputation, checking for spam or malware, and applying content filters. If the email passes all of these checks, it is moved to the next phase of the pipeline. If it fails any of the checks, the email is rejected or quarantined, depending on the configuration.
Delivery: This is the final phase of the pipeline, where emails that have passed all of the checks in the workqueue phase are delivered to their intended recipients. During this phase, the ESA applies any final policies or rules that have been configured, such as encryption or data loss prevention. The email is then sent to the recipient's email server for delivery to the recipient's mailbox.
To summarize, the two phases of the Cisco ESA email pipeline are the workqueue phase and the delivery phase. During the workqueue phase, incoming emails are processed and checked for spam, malware, and other policy violations. If the email passes all of the checks, it is moved to the delivery phase, where it is delivered to the intended recipient after any final policies or rules have been applied.
