A working solution I had for sending email:

from email.MIMEText import MIMEText
from email.Utils import COMMASPACE, formatdate
from email import Encoders
import smtplib

classEMail(object):
        """ Class defines method to send email
        """def__init__(self, mailFrom, server, usrname, password, files, debug=False):
                self.debug = debug

                self.smtpserver = server
                self.EMAIL_PORT = 587
                self.usrname = usrname
                self.password = password


        defsendMessage(self, subject, msgContent, files, mailto):
            """ Send the email message

                Args:

            msg = self.prepareMail(subject, msgContent, files, mailto)

            server.ehlo()
            # use encrypted SSL mode
            server.starttls()
            # to make starttls work

            msg = MIMEMultipart()

            #the Body message
            msg.attach(MIMEText(msgHTML, 'html'))
            msg.attach(MIMEText("Add signature here"))
            if attachments:
                for phile in attachments:
                        # we could check for MIMETypes here
                        part = MIMEBase('application',"octet-stream")
                        part.set_payload(open(phile, "rb").read())
                        Encoders.encode_base64(part)
                        part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(phile))
                        msg.attach(part)
            return msg

I hope this helps.

Solution 2:

My Working solution to format your list in this manner (after many hours of experiment):

["firstemail@mail.com", "secondmail@mail.com", "thirdmail@email.com"]

I used:

to_address = list(str(self.to_address_list).split(","))

to convert my QString into string then into list with splitting with a ","

In my case COMMASPACE was not working, because on splitting a space was already added by default.
