Answer 1

As mentioned by Cid-EL, You have to enable less secure apps in GMAIL settings

However, It's not secure to turn on that perticular option.

Gmail provides API's to perform mail operations. GMAIL API's are supported in many languages.

For Python API : Python with Gmail

For Java API's : Java with Gmail

Little more effort but you can have a secure connection !!

Step 1: Turn on the GMAIL API

Step 2: Install Google client library

pip install --upgrade google-api-python-client

Step 3: Code sample to send a mail using GMAIL API

def get_credentials():
  """Gets valid user credentials from storage.

   home_dir = os.path.expanduser('~')
   credential_dir = os.path.join(home_dir, '.credentials')
   if not os.path.exists(credential_dir):
      os.makedirs(credential_dir)
   credential_path = os.path.join(credential_dir,
                                'gmail-python-quickstart.json')

   store = oauth2client.file.Storage(credential_path)
   credentials = store.get()
   if not credentials or credentials.invalid:
      flow = client.flow_from_clientsecrets(CLIENT_SECRET_FILE, SCOPES)
      flow.user_agent = APPLICATION_NAME
      if flags:
         credentials = tools.run_flow(flow, store, flags)
      else: # Needed only for compatibility with Python 2.6

    try:

        #print 'Message Id: %s' % message['id']
        return message
    except errors.HttpError, error:
        print ('An error occurred: %s' % error)


def main():

    credentials = get_credentials()
    http = credentials.authorize(httplib2.Http())
    service = discovery.build('gmail', 'v1', http=http)

    msg_body = "test message"

    message = CreateMessage("[email protected]", "[email protected]", "Status report of opened tickets", msg_body)

    SendMessage(service, "me", message)

if __name__ == '__main__':
    main()

Let me know if it won't work.

Hope it helps !!
