Here a simple script to send a mail through Django, a very fast web framework written in Python:
sendmail.py:
from django.core.mail import send_mail
send_mail('subject', 'text by Luke', 'jedim@vige.it', ['lsflashboss62@gmail.com'], fail_silently=False)
settings.py:
# Host for sending e-mail.
EMAIL_HOST = 'smtp.gmail.com'
# Port for sending e-mail.
EMAIL_PORT = 25
# Optional SMTP authentication information for EMAIL_HOST.
EMAIL_HOST_USER = 'lsflashboss62@gmail.com'
EMAIL_HOST_PASSWORD = 'passwwooooooorddddd'
EMAIL_USE_TLS = True
If we want send attachments we need to write a new send_mail function. Here an example:
from django.core.mail import get_connection, EmailMessage
import tempfile
def send_mail(subject, message, from_email, recipient_list,
fail_silently=False, auth_user=None, auth_password=None,
connection=None):
connection = connection or get_connection(username=auth_user,
password=auth_password,
fail_silently=fail_silently)
mail = EmailMessage(subject, message, from_email, recipient_list,
connection=connection)
attach = tempfile.NamedTemporaryFile(delete=True)
mail.attach(attach.name, attach.read(), attach.content_type)
return mail.send()
To create a mail crawler, it's very simple:
download Django cron from svn:
svn checkout http://django-cron.googlecode.com/svn/trunk/ django-cron-read-only
and install it in the python path. More details are in the README.txt of the django cron project.
In the INSTALLED_APPS of your settings.py add the django_cron project:
INSTALLED_APPS = (
...
'django_cron',
...
)
Add the rows in the urls.py:
...
import django_cron
...
django_cron.autodiscover()
...
Add a cron.py file in the same path of your settings.py:
from django_cron import cronScheduler, Job
from Myproject.polls import send_mail
class CheckMail(Job):
# run every 300 seconds (5 minutes)
run_every = 300
def job(self):
# This will be executed every 5 minutes
send_mail('ciao', 'ciao da Luke', 'jedim@vige.it', ['lsflashboss62@gmail.com'], fail_silently=False)
cronScheduler.register(CheckMail)
This cron starts at the first request of the webapp and it will send emails each 300 ms
