Reading Email using Pop3 in C#

Following code taken from POP3 Tutorial page and links would help you:

// 
// create client, connect and log in 
Pop3 client = new Pop3();
client.Connect("pop3.example.org");
client.Login("username", "password");

// get message list 
Pop3MessageCollection list = client.GetMessageList();

if (list.Count == 0)
{
    Console.WriteLine("There are no messages in the mailbox.");
}
else
{
    // download the first message 
    MailMessage message = client.GetMailMessage(list[0].SequenceNumber);
    ...
}

client.Disconnect();
