If users report email retrieval issues, which command can a technician use to check the email service status on the server?

Using the command to check the email service status on the server is an appropriate method for diagnosing email retrieval issues. The netstat command provides information about network connections, including the status of ports and protocols used by various services, such as an email server. By running this command, a technician can determine if the email service is listening for connections on the required ports (like SMTP for sending or IMAP/POP3 for retrieving emails) and identify any active connections.

In contrast, the other commands serve different purposes: ping tests the reachability of a host, tracert tracks the path packets take to reach a destination, and ipconfig displays network configuration details like IP addresses and subnet masks but does not directly provide information on the status of specific services. Thus, using netstat is the most effective choice for checking the status of the email service.
