Use Postfix Transport Map and Relayhost Map For Flexible Email Delivery

In previous tutorials we discussed how to quickly set up a full-featured mail server using iRedMail or Modoboa, and we also learned how to set up SMTP relay with Postfix SMTP server to bypass port 25 blocking or IP blacklists. However, you might not want to set up your entire email server to use relay host. We can configure Postfix transport map and relay map so that some emails are delivered via relay host, other emails are sent directly to recipients

Why Use WordPress? What Can You Do With WordPress?

Can you use WordPress for anything other than blogging? To your surprise, yes. WordPress is more than just a blogging tool, and it has helped thousands of websites and web applications to thrive. The use of WordPress powers around 40% of online projects, and today in our blog, we would visit some amazing uses of WordPress other than blogging.
What Is The Use Of WordPress?

WordPress is the most popular website platform in the world. It is the first choice of businesses that want to set a feature-rich and dynamic Content Management System. So, if you ask what WordPress is used for, the answer is – everything. It is a super-flexible, feature-rich and secure platform that offers everything to build unique websites and applications. Let’s start knowing them:

1. Multiple Websites Under A Single Installation
WordPress Multisite allows you to develop multiple sites from a single WordPress installation. You can download WordPress and start building websites you want to launch under a single server. Literally speaking, you can handle hundreds of sites from one single dashboard, which now needs applause.
It is a highly efficient platform that allows you to easily run several websites under the same login credentials. One of the best things about WordPress is the themes it has to offer. You can simply download them and plugin for various sites and save space on sites without losing their speed.

2. WordPress Social Network
WordPress can be used for high-end projects such as Social Media Network. If you don’t have the money and patience to hire a coder and invest months in building a feature-rich social media site, go for WordPress. It is one of the most amazing uses of WordPress. Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress. It would allow you to connect a community page with ease and would provide all the necessary features of a community or social media. It has direct messaging, activity stream, user groups, extended profiles, and so much more. You just have to download and configure it.
If BuddyPress doesn’t meet all your needs, don’t give up on your dreams. You can try out WP Symposium or PeepSo. There are also several themes you can use to build a social network.

3. Create A Forum For Your Brand’s Community
Communities are very important for your business. They help you stay in constant connection with your users and consumers. And allow you to turn them into a loyal customer base. Meanwhile, there are many good technologies that can be used for building a community page – the good old WordPress is still the best.
It is the best community development technology. If you want to build your online community, you need to consider all the amazing features you get with WordPress. Plugins such as BB Press is an open-source, template-driven PHP/ MySQL forum software. It is very simple and doesn’t hamper the experience of the website.
Other tools such as wpFoRo and Asgaros Forum are equally good for creating a community blog. They are lightweight tools that are easy to manage and integrate with your WordPress site easily. However, there is only one tiny problem; you need to have some technical knowledge to build a WordPress Community blog page.

4. Shortcodes
Since we gave you a problem in the previous section, we would also give you a perfect solution for it. You might not know to code, but you have shortcodes. Shortcodes help you execute functions without having to code. It is an easy way to build an amazing website, add new features, customize plugins easily. They are short lines of code, and rather than memorizing multiple lines; you can have zero technical knowledge and start building a feature-rich website or application.
There are also plugins like Shortcoder, Shortcodes Ultimate, and the Basics available on WordPress that can be used, and you would not even have to remember the shortcodes.

5. Build Online Stores
If you still think about why to use WordPress, use it to build an online store. You can start selling your goods online and start selling. It is an affordable technology that helps you build a feature-rich eCommerce store with WordPress.
WooCommerce is an extension of WordPress and is one of the most used eCommerce solutions. WooCommerce holds a 28% share of the global market and is one of the best ways to set up an online store. It allows you to build user-friendly and professional online stores and has thousands of free and paid extensions. Moreover as an open-source platform, and you don’t have to pay for the license.
Apart from WooCommerce, there are Easy Digital Downloads, iThemes Exchange, Shopify eCommerce plugin, and so much more available.

6. Security Features
WordPress takes security very seriously. It offers tons of external solutions that help you in safeguarding your WordPress site. While there is no way to ensure 100% security, it provides regular updates with security patches and provides several plugins to help with backups, two-factor authorization, and more.
By choosing hosting providers like WP Engine, you can improve the security of the website. It helps in threat detection, manage patching and updates, and internal security audits for the customers, and so much more.

Best Practices for Running Your Own Email Server

Plesk Premium Email, powered by Kolab lets you become your own mail service provider in a few easy steps. It’s like creating a personal Gmail service, one that you control from top to bottom. Running the mail server allows you to store your own email, access the mail server’s logs, and access the raw email files in a user’s mailbox.

However, one key concern when running your own mail server is email deliverability. Without being able to effectively reach your customer base, you cannot do business. So, how do you ensure your emails do not end up as spam?

It’s important to follow common rules and best practices when operating a mail server to guarantee your emails always reach their destination. In this quick guide, we’ll walk you through a few things to consider, to make sure that your emails always end up where you intend.

Reputation Management

Much of email delivery depends on your reputation, which is attached to your IPs and domains.

Please note that there might be different types of setups where you can either influence these things or not:

  • If you’re **running your own server **(or VPS – virtual private server) or a bunch of servers with Plesk for shared hosting with WHMCS, you have full influence and control about the following settings.
  • If you’re an **end customer or reseller **of a service provider or hoster using Plesk, unfortunately only your hosting provider can do these modifications for you. In case you want to regain control of your environments, it’s time to move your shared hosting account to your own VPS!
  • If you run Plesk on one of the hyperscale cloud providers such as DigitalOcean, Linode, AWS/Lightsail, Azure, or Google, your default email / SMTP (Port 25 or not) might be blocked on the infrastructure level. If that’s the case, you might need to contact their support to unblock it. In addition, also check that you’re receiving a reverse DNS entry for your IP that is required for operating an email server properly.

The two key-factors that we can influence are:

**1. Ensure other servers can distinguish **between genuine email coming from your server and spam coming from other servers, pretending to come from your server. If you don’t, a spammer can burn your hard-earned reputation while delivering their spam.

You can ensure this by enabling DKIM/DMARC and SPF protection in Plesk under “Server-Wide Mail Settings”.

A Django Module to Easily Send Templated Emails using Django Templates

Django-Templated-Email

Overview

django-templated-email is oriented towards sending templated emails. The library supports template inheritance, adding cc'd and bcc'd recipients, configurable template naming and location.

The send_templated_email method can be thought of as the render_to_response shortcut for email.

Make sure you are reading the correct documentation:

develop branch: https://github.com/vintasoftware/django-templated-email/blob/develop/README.rst

stable pypi/master: https://github.com/vintasoftware/django-templated-email/blob/master/README.rst

Requirements

  • Python (3.6, 3.7, 3.8, 3.9)
  • Django (2.2, 3.1, 3.2)

We highly recommend and only officially support the latest patch release of each Python and Django series.

Getting going - installation

Installing:

pip install django-templated-email

You can add the following to your settings.py (but it works out the box):

TEMPLATED_EMAIL_BACKEND = 'templated_email.backends.vanilla_django.TemplateBackend'

# You can use a shortcut version
TEMPLATED_EMAIL_BACKEND = 'templated_email.backends.vanilla_django'

# You can also use a class directly
from templated_email.backends.vanilla_django import TemplateBackend
TEMPLATED_EMAIL_BACKEND = TemplateBackend

Sending templated emails

Example usage using vanilla_django TemplateBackend backend

Python to send mail:

from templated_email import send_templated_mail
send_templated_mail(
        template_name='welcome',
        from_email='from@example.com',
        recipient_list=['to@example.com'],
        context={
            'username':request.user.username,
            'full_name':request.user.get_full_name(),
            'signup_date':request.user.date_joined
        },
        # Optional:
        # cc=['cc@example.com'],
        # bcc=['bcc@example.com'],
        # headers={'My-Custom-Header':'Custom Value'},
        # template_prefix="my_emails/",
        # template_suffix="email",
)

If you would like finer control on sending the email, you can use get_templated_email, which will return a django EmailMessage object, prepared using the vanilla_django backend:

from templated_email import get_templated_mail
get_templated_mail(
        template_name='welcome',
        from_email='from@example.com',
        to=['to@example.com'],
        context={
            'username':request.user.username,
            'full_name':request.user.get_full_name(),
            'signup_date':request.user.date_joined
        },
        # Optional:
        # cc=['cc@example.com'],
        # bcc=['bcc@example.com'],
        # headers={'My-Custom-Header':'Custom Value'},
        # template_prefix="my_emails/",
        # template_suffix="email",
)

You can also cc and bcc recipients using cc=['example@example.com'].

Your template

The templated_email/ directory needs to be the templates directory.

The backend will look in my_app/templates/templated_email/welcome.email :

{% block subject %}My subject for {{username}}{% endblock %}
{% block plain %}
  Hi {{full_name}},

  You just signed up for my website, using:
      username: {{username}}
      join date: {{signup_date}}

  Thanks, you rock!
{% endblock %}

If you want to include an HTML part to your emails, simply use the 'html' block :

{% block html %}
  <p>Hi {{full_name}},</p>

  <p>You just signed up for my website, using:
      <dl>
        <dt>username</dt><dd>{{username}}</dd>
        <dt>join date</dt><dd>{{signup_date}}</dd>
      </dl>
  </p>

  <p>Thanks, you rock!</p>
{% endblock %}

The plain part can also be calculated from the HTML using html2text. If you don't specify the plain block and html2text package is installed, the plain part will be calculated from the HTML part. You can disable this behaviour in settings.py :

TEMPLATED_EMAIL_AUTO_PLAIN = False

You can also specify a custom function that converts from HTML to the plain part :

def convert_html_to_text(html):
    ...

TEMPLATED_EMAIL_PLAIN_FUNCTION = convert_html_to_text

You can globally override the template dir, and file extension using the following variables in settings.py :

TEMPLATED_EMAIL_TEMPLATE_DIR = 'templated_email/' #use '' for top level template dir, ensure there is a trailing slash
TEMPLATED_EMAIL_FILE_EXTENSION = 'email'

You can also set a value for template_prefix and template_suffix for every time you call send_templated_mail, if you wish to store a set of templates in a different directory. Remember to include a trailing slash.

Using with Django Anymail

Anymail integrates several transactional email service providers (ESPs) into Django, with a consistent API that lets you use ESP-added features without locking your code to a particular ESP. It supports Mailgun, Postmark, SendGrid, SparkPost and more.

You can use it with django-templated-email, just follow their instructions in their quick start to configure it.

Optionally you can use their custom EmailMessage class with django-templated-email by using the following settings:

# This replaces django.core.mail.EmailMessage
TEMPLATED_EMAIL_EMAIL_MESSAGE_CLASS='anymail.message.AnymailMessage'

# This replaces django.core.mail.EmailMultiAlternatives
TEMPLATED_EMAIL_EMAIL_MULTIALTERNATIVES_CLASS='anymail.message.AnymailMessage'

Inline images

You can add inline images to your email using the InlineImage class.

First get the image content from a file or a ImageField:

# From a file
with open('pikachu.png', 'rb') as pikachu:
  image = pikachu.read()

# From an ImageField
# Suppose we have this model
class Company(models.Model):
  logo = models.ImageField()

image = company.logo.read()

Then create an instance of InlineImage:

from templated_email import InlineImage

inline_image = InlineImage(filename="pikachu.png", content=image)

Now pass the object on the context to the template when you send the email.

send_templated_mail(template_name='welcome',
                    from_email='from@example.com',
                    recipient_list=['to@example.com'],
                    context={'pikachu_image': inline_image})

Finally in your template add the image on the html template block:

<img src="{{ pikachu_image }}">

Note: All InlineImage objects you add to the context will be attached to the e-mail, even if they are not used in the template.

Add link to view the email on the web

# Add templated email to INSTALLED_APPS
INSTALLED_APPS = [
  ...
  'templated_email'
]
# and this to your url patterns
url(r'^', include('templated_email.urls', namespace='templated_email')),
# when sending the email use the *create_link* parameter.
send_templated_mail(
    template_name='welcome', from_email='from@example.com',
    recipient_list=['to@example.com'],
    context={}, create_link=True)

And, finally add the link to your template.

<!-- With the 'if' the link will only appear on the email. -->
{% if email_uuid %}
  <!-- Note: you will need to add your site since you will need to access
             it from the email -->
  You can view this e-mail on the web here:
  <a href="http://www.yoursite.com{% url 'templated_email:show_email' uuid=email_uuid %}">
    here
  </a>
{% endif %}

Notes:

  • A copy of the rendered e-mail will be stored on the database. This can grow if you send too many e-mails. You are responsible for managing it.
  • If you use InlineImage all images will be uploaded to your media storage, keep that in mind too.

Class Based Views

It's pretty common for emails to be sent after a form is submitted. We include a mixin to be used with any view that inherit from Django's FormMixin.

In your view add the mixin and the usual Django's attributes:

from templated_email.generic_views import TemplatedEmailFormViewMixin

class AuthorCreateView(TemplatedEmailFormViewMixin, CreateView):
    model = Author
    fields = ['name', 'email']
    success_url = '/create_author/'
    template_name = 'authors/create_author.html'

By default the template will have the form_data if the form is valid or from_errors if the form is not valid in it's context.

You can view an example here

Now you can use the following attributes/methods to customize it's behavior:

Attributes:

templated_email_template_name (mandatory if you don't implement templated_email_get_template_names()):

String naming the template you want to use for the email. ie: templated_email_template_name = 'welcome'.

templated_email_send_on_success (default: True):

This attribute tells django-templated-email to send an email if the form is valid.

templated_email_send_on_failure (default: False):

This attribute tells django-templated-email to send an email if the form is invalid.

templated_email_from_email (default: settings.TEMPLATED_EMAIL_FROM_EMAIL):

String containing the email to send the email from.

Methods:

templated_email_get_template_names(self, valid) (mandatory if you don't set templated_email_template_name):

If the method returns a string it will use it as the template to render the email. If it returns a list it will send the email only with the first existing template.

templated_email_get_recipients(self, form) (mandatory):

Return the recipient list to whom the email will be sent to. ie:

def templated_email_get_recipients(self, form):
    return [form.data['email']]

templated_email_get_context_data(**kwargs) (optional):

Use this method to add extra data to the context used for rendering the template. You should get the parent class's context from calling super. ie:

def templated_email_get_context_data(self, **kwargs):
    context = super(ThisClassView, self).templated_email_get_context_data(**kwargs)
    # add things to context
    return context

templated_email_get_send_email_kwargs(self, valid, form) (optional):

Add or change the kwargs that will be used to send the e-mail. You should call super to get the default kwargs. ie:

def templated_email_get_send_email_kwargs(valid, form):
  kwargs = super(ThisClassView, self).templated_email_get_send_email_kwargs(valid, form)
  kwargs['bcc'] = ['admin@example.com']
  return kwargs

templated_email_send_templated_mail(*args, **kwargs) (optional):

This method calls django-templated-email's send_templated_mail method. You could change this method to use a celery's task for example or to handle errors.

Future Plans

See https://github.com/vintasoftware/django-templated-email/issues?state=open

Using django_templated_email in 3rd party applications

If you would like to use django_templated_email to handle mail in a reusable application, you should note that:

  • Your calls to send_templated_mail should set a value for template_dir, so you can keep copies of your app-specific templates local to your app (although the loader will find your email templates if you store them in <your app>/templates/templated_email, if TEMPLATED_EMAIL_TEMPLATE_DIR has not been overridden)
  • If you do (and you should) set a value for template_dir, remember to include a trailing slash, i.e. 'my_app_email/'
  • The deployed app may use a different backend which doesn't use the django templating backend, and as such make a note in your README warning developers that if they are using django_templated_email already, with a different backend, they will need to ensure their email provider can send all your templates (ideally enumerate those somewhere convenient)

Notes on specific backends

Using vanilla_django

This is the default backend, and as such requires no special configuration, and will work out of the box. By default it assumes the following settings (should you wish to override them):

TEMPLATED_EMAIL_TEMPLATE_DIR = 'templated_email/' #Use '' for top level template dir
TEMPLATED_EMAIL_FILE_EXTENSION = 'email'

For legacy purposes you can specify email subjects in your settings file (but, the preferred method is to use a {% block subject %} in your template):

TEMPLATED_EMAIL_DJANGO_SUBJECTS = {
    'welcome':'Welcome to my website',
}

Additionally you can call send_templated_mail and optionally override the following parameters:

template_prefix='your_template_dir/'  # Override where the method looks for email templates (alternatively, use template_dir)
template_suffix='email'               # Override the file extension of the email templates (alternatively, use file_extension)
cc=['fubar@example.com']              # Set a CC on the mail
bcc=['fubar@example.com']             # Set a BCC on the mail
template_dir='your_template_dir/'     # Override where the method looks for email templates
connection=your_connection            # Takes a django mail backend connection, created using **django.core.mail.get_connection**
auth_user='username'                  # Override the user that the django mail backend uses, per **django.core.mail.send_mail**
auth_password='password'              # Override the password that the django mail backend uses, per **django.core.mail.send_mail**

Releasing a new version of this package:

Update CHANGELOG file.

Execute the following commands:
