class Email(object):
    _message=None

    def __init__(self,to,eFrom,subject,body,Files=[]):
        msg = MIMEMultipart()
        msg['From'] = eFrom
        msg['To'] = to
        msg['Subject'] = subject
        msg.attach(MIMEText(body, 'plain'))

        for f in Files:
            #part = ('application',"octet-stream")
            #part.set_payload(open(f,"rb").read())
            part = MIMEApplication(open(f,'rb').read())
            #Encoders.encode_base64(part)
            part.add_header('Content-Disposition', 'attachment', filename=str(os.path.basename(f)))
            msg.attach(part)
        self._message = msg

    def sendEmail(self,host,port,username,password):
        server = smtplib.SMTP(host, port)
        server.starttls()
        server.login(username,password)
        server.sendmail(self._message['From'],self._message['To'],self._message.as_string())
        server.quit()
