      To close a connection, simply call the Disconnect or DisconnectAsync methods of the Pop3 class. The following steps show you how to close a connection with the Disconnect method.

      1. Add using directives to your code to create aliases for existing namespaces and avoid having to type the fully qualified type names. The code looks similar to the following:
        using System;
        using System.Text;
        using ComponentPro.Net.Mail;
        
      2. Create a new instance of the Pop3 class.
      3. Now you can connect to the POP3 server with Connect methods. The code looks similar to the following:
        // Create a new instance of the Pop3 class.
        Pop3 client = new Pop3();
        
        // Connect to the server.
        client.Connect("myserver");
        
        // Or you can specify the POP3 port with 
        // client.Connect("myserver", 110);
        
      4. Use your user name and password to login with Authenticate methods. The code looks similar to the following:
        // Login to the server.
        client.Authenticate("user", "password");
        
      5. Do your work like listing mailboxes, downloading/uploading mail messages ,etc. The code looks similar to the following:
        StringBuilder sb = new StringBuilder();
        
        Pop3MessageCollection list = client.ListMessages(Pop3EnvelopeParts.Size | Pop3EnvelopeParts.UniqueId);
        for (int i = 0; i < list.Count; i++)
        {
            sb.AppendFormat("{0} - {1}\r\n", i + 1, list[i].UniqueId);
        }
        
        Console.WriteLine(sb.ToString());
        
      6. After completing your work, call the Disconnect method to close the POP3 session. The code looks similar to the following:
        // Close the connection.
        client.Disconnect();
