Email marketing involves sending bulk emails through SMTP servers. Monitoring these servers to ensure they are functioning correctly is essential for successful email campaigns. Here are some ways netstat can help:
Identifying Open Connections: Netstat can show all open connections to your SMTP server, helping you understand the server's load and identify potential bottlenecks. Monitoring Port Activity: By displaying active ports, netstat helps ensure that your SMTP server is listening on the correct ports and that there are no unauthorized connections. Detecting Issues: Netstat can alert you to abnormal network activity, such as a sudden spike in connections, which could indicate a security breach or a spam attack.
