Pop3Server

What is Pop3Server?

Pop3Server is a simple, yet highly functional POP3 server implementation. It is based on the structure of the SmtpServer project by cosullivan, with modifications to implement POP3 instead of SMTP. Written entirely in C#, showcases the potential for a full-featured POP3 server built on .NET.

Acknowledgements

Special thanks to cosullivan for the original SmtpServer project, which served as the foundation for Pop3Server.

What's New?

This project is in its early stages and is a proof of concept for a POP3 server. The code structure and architecture have been adapted from the original SmtpServer project to support POP3.

How can it be used?

To get the Pop3Server up and running, you can follow this example from the included project in the example\Pop3WorkerService folder. Here's how to start the server:

var options = new Pop3ServerOptionsBuilder()
  .ServerName("POP3 Server")
  .Endpoint(endpoint => endpoint
    .Port(110)
    .AllowUnsecureAuthentication())
  .Build();

var serviceProvider = new ServiceProvider();
serviceProvider.Add(new ConsoleUserAuthenticator());
serviceProvider.Add(new ConsoleMessageStore());

var pop3Server = new Pop3Server.Pop3Server(options, serviceProvider);
await pop3Server.StartAsync(CancellationToken.None);

Available Features

Pop3Server currently supports the following POP3 commands:

• CAPA
• USER
• PASS
• DELE
• LIST
• NOOP
• PROXY
• RETR
• RSET
• STAT
• STLS
• TOP
• UIDL
• QUIT

Example Project

An example project demonstrating how to set up and run the Pop3Server is included in the example\Pop3WorkerService folder. This example provides a basic implementation to help you get started with using and customizing the server.
