Added basic mailer class.

#!/usr/bin/env python

import smtplib

from config import Config

class Mailer(object):

    def __init__(self):

        config = Config("/etc/vos_ts/vos_ts.conf")

        params = config.loadSection("mail")

        self.smtpServer = params["smtp_server"]

        self.smtpPort = params.getint("smtp_port")

        self.sender = params["no_reply_email"]

        self.receivers = []

        self.message = None

    def sender(self, sender):

        self.sender = sender

    def addReceiver(self, receiver):

        self.receivers.append(receiver)

    def setMessage(self, msg):

        self.message = msg

    def send(self):

        try:

            smtpObj = smtplib.SMTP(self.smtpServer, self.smtpPort)

            smtpObj.sendmail(self.sender, self.receivers, self.message)

            print("Message sent!")

        except SMTPException:

            print("Error: cannot send email message.")

# Test

#m = Mailer()

#m.setMessage("Hello world!")

#m.addReceiver("cristiano.urban@inaf.it")

#m.send()
