Postal SMTP install and setup on a virtual server

Postal is a full suite for mail delivery with robust features suited for running a bulk email sending SMTP server. Postal is open source and free. Some of its features are: - UI for maintaining different aspects of your mail server - Runs on containers, hence allows for up and down horizontal scaling - Email security features such as spam and antivirus - IP pools to help you maintain a good sending reputation by sending via multiple IPs - Multitenant support - multiple users, domains and organizations - Monitoring queue for outgoing and incoming mail - Built in DNS setup and monitoring to ensure mail domains are set up correctly List of full postal features

Possible cloud providers to use with Postal

You can use Postal with any VPS or Linux server providers of your choice, however here are some we recommend: Vultr Cloud (Get free $300 credit) - In case your SMTP port is blocked, you can contact Vultr support, and they will open it for you after providing a personal identification method. DigitalOcean (Get free $200 Credit) - You will also need to contact DigitalOcean support for SMTP port to be open for you. Hetzner ( Get free €20) - SMTP port is open for most accounts, if yours isn't, contact the Hetzner support and request for it to be unblocked for you Contabo (Cheapest VPS) - Contabo doesn't block SMTP ports. In case you are unable to send mail, contact support. Interserver

Postal Minimum requirements

- At least 4GB of RAM - At least 2 CPU cores - At least 25GB disk space - You can use docker or any Container runtime app. Ensure Docker Compose plugin is also installed. - Port 25 outbound should be open (A lot of cloud providers block it)

Postal Installation

Should be installed on its own server, meaning, no other items should be running on the server. A fresh server install is recommended. Broad overview of the installation procedure - Install Docker and the other needed apps - Configuration of postal and add DNS entries - Start Postal - Make your first user - Login to the web interface to create virtual mail servers Step by step install Postal Step 1 : Install docker and additional system utilities In this guide, I will use Debian 12 . Feel free to follow along with Ubuntu. The OS to be used does not matter, provided you can install docker or any docker alternative for running container images. Commands for installing Docker on Debian 12 (Read the comments to understand what each command does): #Uninstall any previously installed conflicting software . If you have none of them installed it's ok for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done #Add Docker's official GPG key: sudo apt-get update sudo apt-get install ca-certificates curl -y sudo install -m 0755 -d /etc/apt/keyrings sudo curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc sudo chmod a+r /etc/apt/keyrings/docker.asc #Add the Docker repository to Apt sources: echo "deb https://download.docker.com/linux/debian $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null sudo apt-get update #Install the docker packages sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y #You can verify that the installation is successful by running the hello-world image sudo docker run hello-world Add the current user to the docker group so that you don't have to use sudo when not logged in as the root user. ##Add your current user to the docker group. sudo usermod -aG docker $USER #Reboot the server sudo reboot Finally test if you can run docker without sudo ##Test that you don't need sudo to run docker docker run hello-world Step 2 : Get the postal installation helper repository The Postal installation helper has all the docker compose files and the important bootstrapping tools needed for generating configuration files. Install various needed tools #Install additional system utlities apt install git vim htop curl jq -y Then clone the helper repository. sudo git clone https://github.com/postalserver/install /opt/postal/install sudo ln -s /opt/postal/install/bin/postal /usr/bin/postal Step 3 : Install MariaDB database Here is a sample MariaDB container from the postal docs. But you can use the docker compose file below it. docker run -d --name postal-mariadb -p 127.0.0.1:3306:3306 --restart always -e MARIADB_DATABASE=postal -e MARIADB_ROOT_PASSWORD=postal mariadb Here is a tested mariadb compose file to run a secure MariaDB 11.4 container. You can change the version to any image you prefer. vi docker-compose.yaml services: mariadb: image: mariadb:11.4 container_name: postal-mariadb restart: unless-stopped environment: MYSQL_ROOT_PASSWORD: ${DB_ROOT_PASSWORD} volumes: - mariadb_data:/var/lib/mysql network_mode: host # Set to use the host's network mode security_opt: - no-new-privileges:true read_only: true tmpfs: - /tmp - /run/mysqld healthcheck: test: interval: 30s timeout: 10s retries: 5 volumes: mariadb_data: You need to create an environment file with the Database password . To simplify things, postal will use the root user to access the Database.env file example is below. Place it in the same location as the compose file. DB_ROOT_PASSWORD=ExtremelyStrongPasswordHere Run docker compose up -d and ensure the database is healthy. Step 4 : Bootstrap the domain for your Postal web interface & Database configs First add DNS records for your postal domain. The most significant records at this stage are the A and/or AAAA records. This is the domain where you'll be accessing the postal UI and for simplicity will also act as the SMTP server. If using Cloudflare, turn off the Cloudflare proxy. sudo postal bootstrap postal.yourdomain.com The above will generate three files in /opt/postal/config. - postal.yml is the main postal configuration file - signing.key is the private key used to sign various things in Postal - Caddyfile is the configuration for the Caddy web server Open /opt/postal/config/postal.yml and add all the values for DB and other settings. Go through the file and see what else you can edit. At the very least, enter the correct DB details for postal message_db and main_db. Step 5 : Initialize the Postal database and create an admin user postal initialize postal make-user If everything goes well with postal initialize, then celebrate. This is the part where you may face some issues due to DB connection failures. Step 6 : Start running postal # run postal postal start #checking postal status postal status # If you make any config changes in future you can restart postal like so # postal restart Step 7 : Proxy for web traffic To handle web traffic and ensure TLS termination you can use any proxy server of your choice, nginx, traefik , caddy etc. Based on Postal documentation, the following will start up caddy. You can use the compose file below it. Caddy is easy to use and does a lot for you out of the box. Ensure your A records are pointing to your server before running Caddy. docker run -d --name postal-caddy --restart always --network host -v /opt/postal/config/Caddyfile:/etc/caddy/Caddyfile -v /opt/postal/caddy-data:/data caddy Here is a compose file you can use instead of the above docker run command. Name it something like caddy-compose.yaml services: postal-caddy: image: caddy container_name: postal-caddy restart: always network_mode: host volumes: - /opt/postal/config/Caddyfile:/etc/caddy/Caddyfile - /opt/postal/caddy-data:/data You can run it by doing docker compose -f caddy-compose.yaml up -d Now it's time to go to the browser and login. Use the domain, bootstrapped earlier. Add an organization, create server and add a domain. This is done via the UI and it is very straight forward. For every domain you add, ensure to add the DNS records you are provided.

Enable IP Pools

One of the reasons why Postal is great for bulk email sending, is because it allows for sending emails using multiple IPs in a round-robin fashion. Pre-requisites - Ensure the IPs you want to add as part of the pool, are already added to your VPS/server. Every cloud provider has a documentation for adding additional IPs, make sure you follow their guide to add all the IPs to the network. When you run ip a , you should see the IP addresses you intend to use in the pool. Enabling IP pools in the Postal config First step is to enable IP pools settings in the postal configuration, then restart postal. Add the following configuration in the postal.yaml (/opt/postal/config/postal.yml) file to enable pools. If the section postal: , exists, then just add use_ip_pools: true under it. postal: use_ip_pools: true Then restart postal. postal stop && postal start The next step is to go to the postal interface on your browser. A new IP pools link is now visible at the top right corner of your postal dashboard. You can use the IP pools link to add a pool, then assign IP addresses in the pools. A pool could be something like marketing, transactions, billing, general etc. Once the pools are created and IPs assigned to them, you can attach a pool to an organization. This organization can now use the provided IP addresses to send emails. Open up an organization and assign a pool to it. Organizations → choose IPs → choose pools . You can then assign the IP pool to servers from the server's Settings page. You can also use the IP pool to configure IP rules for the organization or server. At any point, if you are lost, look at the Postal documentation. Read the full article

Using Docker in Software Development

Docker has become a vital tool in modern software development. It allows developers to package applications with all their dependencies into lightweight, portable containers. Whether you're building web applications, APIs, or microservices, Docker can simplify development, testing, and deployment.

What is Docker?

Docker is an open-source platform that enables you to build, ship, and run applications inside containers. Containers are isolated environments that contain everything your app needs—code, libraries, configuration files, and more—ensuring consistent behavior across development and production.

Why Use Docker?

Consistency: Run your app the same way in every environment.

Isolation: Avoid dependency conflicts between projects.

Portability: Docker containers work on any system that supports Docker.

Scalability: Easily scale containerized apps using orchestration tools like Kubernetes.

Faster Development: Spin up and tear down environments quickly.

Basic Docker Concepts

Image: A snapshot of a container. Think of it like a blueprint.

Container: A running instance of an image.

Dockerfile: A text file with instructions to build an image.

Volume: A persistent data storage system for containers.

Docker Hub: A cloud-based registry for storing and sharing Docker images.

Example: Dockerizing a Simple Python App

Let’s say you have a Python app called app.py: # app.py print("Hello from Docker!")

Create a Dockerfile: # Dockerfile FROM python:3.10-slim COPY app.py . CMD ["python", "app.py"]

Then build and run your Docker container: docker build -t hello-docker . docker run hello-docker

This will print Hello from Docker! in your terminal.

Popular Use Cases

Running databases (MySQL, PostgreSQL, MongoDB)

Hosting development environments

CI/CD pipelines

Deploying microservices

Local testing for APIs and apps

Essential Docker Commands

docker build -t <name> . — Build an image from a Dockerfile

docker run <image> — Run a container from an image

docker ps — List running containers

docker stop <container_id> — Stop a running container

docker exec -it <container_id> bash — Access the container shell

Docker Compose

Docker Compose allows you to run multi-container apps easily. Define all your services in a single docker-compose.yml file and launch them with one command: version: '3' services: web: build: . ports: - "5000:5000" db: image: postgres

Start everything with:docker-compose up

Best Practices

Use lightweight base images (e.g., Alpine)

Keep your Dockerfiles clean and minimal

Ignore unnecessary files with .dockerignore

Use multi-stage builds for smaller images

Regularly clean up unused images and containers

Conclusion

Docker empowers developers to work smarter, not harder. It eliminates "it works on my machine" problems and simplifies the development lifecycle. Once you start using Docker, you'll wonder how you ever lived without it!

A Beginner’s Guide to Docker: Building and Running Containers in DevOps

Docker has revolutionized the way applications are built, shipped, and run in the world of DevOps. As a containerization platform, Docker enables developers to package applications and their dependencies into lightweight, portable containers, ensuring consistency across environments. This guide introduces Docker’s core concepts and practical steps to get started.

What is Docker? Docker is an open-source platform that allows developers to: Build and package applications along with their dependencies into containers.

Run these containers consistently across different environments. Simplify software development, deployment, and scaling processes.

2. Why Use Docker in DevOps? Environment Consistency: Docker containers ensure that applications run the same in development, testing, and production.

Speed: Containers start quickly and use system resources efficiently.

Portability: Containers can run on any system that supports Docker, whether it’s a developer’s laptop, an on-premises server, or the cloud.

Microservices Architecture: Docker works seamlessly with microservices, enabling developers to build, deploy, and scale individual services independently.

3. Key Docker Components Docker Engine:

The core runtime for building and running containers.

Images: A blueprint for containers that include the application and its dependencies. Containers: Instances of images that are lightweight and isolated.

Dockerfile: A script containing instructions to build a Docker image.

Docker Hub: A repository for sharing Docker images.

4. Getting Started with Docker

Step 1: Install Docker Download and install Docker Desktop for your operating system from Docker’s official site.

Step 2: Write a Dockerfile Create a Dockerfile to define your application environment.

Example for a Python app:

dockerfile Edit

# Use an official Python runtime as a base image FROM python:3.9-slim

# Set the working directory WORKDIR /app

# Copy project files COPY . .

# Install dependencies RUN pip install -r requirements.txt # Define the command to run the app CMD [“python”, “app.py”]

Step 3: Build the Docker Image Run the following command to build the image:

bash Copy Edit docker build -t my-python-app .

Step 4: Run the Container Start a container from your image:

bash

Edit docker run -d -p 5000:5000 my-python-app

This maps port 5000 of the container to port 5000 on your host machine.

Step 5: Push to Docker Hub Share your image by pushing it to Docker Hub: bash

Edit docker tag my-python-app username/my-python-app docker push username/my-python-app

5. Practical Use Cases in DevOps Continuous Integration/Continuous Deployment (CI/CD):

Docker is commonly used in pipelines for building, testing, and deploying applications.

Microservices:

Each service runs in its own container, isolated from others.

Scalability:

Containers can be easily scaled up or down based on demand.

Testing:

Test environments can be quickly spun up and torn down using Docker containers.

6. Best Practices Keep Docker images small by using minimal base images. Avoid hardcoding sensitive data into images; use environment variables instead.

Use Docker Compose to manage multi-container applications. Regularly scan images for vulnerabilities using Docker’s built-in security tools.

Conclusion

Docker simplifies the development and deployment process, making it a cornerstone of modern DevOps practices. By understanding its basics and starting with small projects, beginners can quickly leverage Docker to enhance productivity and streamline workflows.
