Emailing with Python. I’ve been in need of some Jython code that would allow me to send out emails with 1 to n files attached to the message. I puttered around my books and a few websites but couldn’t find exactly what I needed.

HelloEmailer.py

#!/usr/bin/env python

import smtplib, string, os
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
from email.MIMEBase import MIMEBase
from email.Encoders import encode_base64

class Emailer():
    '''Creates a simple object to interact with to send out mass emails'''

    def __init__(self):
        self.__server = smtplib.SMTP()

    def send_email(self, from_address, to_addresses,
                              subject, message, files=[]):
        '''
            from_address - a string, the email for the from field.
            to_addrs - a list object containing the email address to send
                        the message to. Ex. ['thedude@freecog.com']
            subject - a short subject line for the email.
            message - the message to send to the recipients.
            files - a list of paths to the files to attache to the email.

                            % os.path.basename(file) )
            self.msg.attach( part )
