Thanks you all for your contribution. Finally I use POP3:

public string Connect_Email()
{
    string Res = "";
    try
    {
        Pop3Client email = new Pop3Client("login", "password", "server");
        email.OpenInbox();

        while (email.NextEmail())
        {
            if (email.IsMultipart)
            {
                IEnumerator enumerator = email.MultipartEnumerator;
                while (enumerator.MoveNext())
                {
                    Pop3Component multipart = (Pop3Component)
                    enumerator.Current;
                    if (multipart.IsBody)
                    {
                        //Console.WriteLine("Multipart body:" + multipart.Name);
                    }
                    else
                    {
                        //Console.WriteLine("Attachment name=" +    multipart.Name); // ... etc
                        byte[] filebytes = Convert.FromBase64String(multipart.Data);

                        //Search FileName
                        int Begin = multipart.ContentType.IndexOf("name=");
                        string leFileNale = multipart.ContentType.Substring(Begin + 5, 12);

                        FileStream LeFS = new FileStream(filePath + "\\" + leFileNale, FileMode.Create, FileAccess.Write, FileShare.None);
                        LeFS.Write(filebytes, 0, filebytes.Length);
                        LeFS.Close();
                    }
                }
            }
        }
        email.CloseConnection();
    }
    catch (Pop3LoginException)
    {
        Res = "Vous semblez avoir un problème de connexion!";
    }
    return Res;
}

It work well, but still I have to find and download the attachement my self.

byte[] filebytes = Convert.FromBase64String(multipart.Data);

//Search FileName
int Begin = multipart.ContentType.IndexOf("name=");
string leFileNale = multipart.ContentType.Substring(Begin + 5, 12);

FileStream LeFS = new FileStream(filePath + "\\" + leFileNale, FileMode.Create, FileAccess.Write, FileShare.None);
LeFS.Write(filebytes, 0, filebytes.Length);
LeFS.Close();

If you're trying to read e-mail via POP3, I would recommend using the OpenPOP.NET library instead of rolling your own. It's pretty easy to use.

Try something like this

using(Pop3 pop3 = new Pop3())  
 {  
     pop3.Connect("server");  
     pop3.UseBestLogin("user", "password");  
     foreach (string uid in pop3.GetAll())  
     {  
         IMail email = new MailBuilder()
         .CreateFromEml(pop3.GetMessageByUID(uid));  
         Console.WriteLine(email.Subject);  
         // save all attachments to disk  
         email.Attachments.ForEach(mime => mime.Save(mime.SafeFileName));  
     }  
     pop3.Close();  
 }
