How to check POP3 mailbox for new messages via Powershell?

Is it possible to check POP3 mailbox for new e-mails via Powershell? And if possible, how can this be achieved?

This link provides some information 开发者_JS百科but doesn't suit me. I know about NetCmdlets but would prefer not to use commercial tools. Also I do not want to start outlook.application. In fact, my goal is to avoid starting outlook, as long as it possible (for performance reasons)

As far as I know, there is no native POP3 class in the .NET FRAMEWORK. So you can write one using sockets or you can use an exe client. You can try GetMail for Windows.

What about creating a TCP connection using TCPClient, and next, create a NetworkStream object, connected to the TCPClient object, to read data from the server?

You'll need System.Net.Sockets and System.Net.IO.

Anyway I would search for a C# answer and then try to get it to powershell.
