可以使用OpenPop.dll.

    Pop3Client objPOP3Client = new Pop3Client();
    int intTotalEmail = 0;
    DataTable dtEmail = new DataTable();
    object[] objMessageParts;

    try
    {
        dtEmail = GetAllEmailStructure();

        if (objPOP3Client.Connected)
            objPOP3Client.Disconnect();

        objPOP3Client.Connect(strHostName, intPort, bulUseSSL);
        try
        {
            objPOP3Client.Authenticate(strUserName, new Common()._Decode(strPassword));
            intTotalEmail = objPOP3Client.GetMessageCount();

            AddMapping();

            for (int i = 1; i <= intTotalEmail; i++)
            {
                objMessageParts = GetMessageContent(i, ref objPOP3Client, dtExistMailList);

                if (objMessageParts != null && objMessageParts[0].ToString() == "0")
                {
                    AddToDtEmail(objMessageParts, i, dtEmail, dtUserList, dtTicketIDList, dtBlacklistEmails, dtBlacklistSubject, dtBlacklistDomains);
                }
            }
        }
        catch (Exception ex)
        {
        }
    }
    catch …
