Consider the situation of an employee who is using their computer to send and receive email at their place of employment. However, the mail server is situated on a distinct network from the physical connectivity networks, which are all Ethernet networks. Each of the two networks—the employee's network and the mail server's network—is linked by a single router, which also has a connection to the Internet via the workplace's Internet service provider.

Include any protocols that are used and any encapsulation/decapsulation that takes place when data moves between the employee's email client, local mail server, and distant mail servers in your explanation of how the email client communicates with the email server.
