Postal is a feature-rich mail server application widely used as an alternative to Sendgrid, Mailchimp, Mailgun and other similar SMPT servers. You can use Postal to send out bulk emails, newsletters etc. This guide should work on other Linux VPS systems as well but it was tested and written for an Ubuntu 16.04 VPS.<!--more--><\/p>\n<h2>Requirements<\/h2>\n<p>There are some requirements for this Postal setup.<\/p>\n<ul>\n<li>An Ubuntu VPS<\/li>\n<li>Ruby version 2.3 or up, MySQL\/MariaDB, RabbitMQ, Node.js and Git installed on your server<\/li>\n<\/ul>\n<p>If you get one of our Managed Linux VPS hosting plans, we&#8217;ll install all requirements and set up your server with Postal.<\/p>\n<h2>1. Install Basic Packages and Dependencies<\/h2>\n<p>First, install some packages and dependencies on your system, including nginx, mariadb, git etc.<\/p>\n<pre>[user]$ sudo apt-get install python-software-properties  software-properties-common\r\n[user]$ sudo apt-get install git nginx mariadb-server build-essential libmysqlclient-dev<\/pre>\n<h2>2. Install Node.js<\/h2>\n<p>Next, install the latest version of Node.js on your system. To install the latest (7.x) version, use the following command:<\/p>\n<pre>[user]$ curl -sL https:\/\/deb.nodesource.com\/setup_7.x | sudo -E bash -\r\n[user]$ sudo apt-get install nodejs<\/pre>\n<h2>3. Install Ruby 2.3<\/h2>\n<p>After Nodejs, we need to install Ruby and add the Ruby PPAs:<\/p>\n<pre>[user]$ sudo apt-add-repository ppa:brightbox\/ruby-ng -y\r\n[user]$ sudo apt-key adv --recv-keys --keyserver hkp:\/\/keyserver.ubuntu.com:80 0xF1656F24C74CD1D8<\/pre>\n<p>Next, install Ruby 2.3:<\/p>\n<pre>[user]$ sudo apt-get update\r\n[user]$ sudo apt-get install -y ruby2.3 ruby2.3-dev<\/pre>\n<h2>4. Install RabbitMQ Server<\/h2>\n<p>RabbitMQ will be used for messaging, so enable the Erlang PPA with the following command:<\/p>\n<pre>[user]$ wget https:\/\/packages.erlang-solutions.com\/erlang-solutions_1.0_all.deb\r\n[user]$ sudo dpkg -i erlang-solutions_1.0_all.deb<\/pre>\n<p>You also need to enable the RabbitMQ server PPA:<\/p>\n<pre>[user]$ echo 'deb http:\/\/www.rabbitmq.com\/debian\/ testing main' | sudo tee \/etc\/apt\/sources.list.d\/rabbitmq.list\r\n[user]$ wget -O- https:\/\/www.rabbitmq.com\/rabbitmq-release-signing-key.asc | sudo apt-key add -<\/pre>\n<p>Next, you can install the RabbitMQ server along with its dependencies:<\/p>\n<pre>[user]$ sudo apt-get update\r\n[user]$ sudo apt-get install erlang erlang-nox rabbitmq-server<\/pre>\n<h2>5. Create Database in MySQL<\/h2>\n<p>Create a database and user for your Postal mail server and grant permissions to the user:<\/p>\n<pre>[user]$ mysql -u root -p\r\nEnter password:*******<\/pre>\n<pre>mysql&gt; CREATE DATABASE postal CHARSET utf8mb4 COLLATE utf8mb4_unicode_ci;\r\nmysql&gt; GRANT ALL ON `postal`.* TO `postal`@`127.0.0.1` IDENTIFIED BY \"passw0rd\";\r\nmysql&gt; GRANT ALL ON `postal-%`.* TO `postal`@`127.0.0.1` IDENTIFIED BY \"passw0rd\";\r\nmysql&gt; FLUSH PRIVILEGES;<\/pre>\n<p>Always use a strong password.<\/p>\n<h2>6. Create RabbitMQ VirtualHost<\/h2>\n<p>Next, create a VirtualHost in your RabbitMQ server and create a new user for your app<\/p>\n<pre>[user]$ rabbitmqctl add_vhost \/postal\r\n[user]$ rabbitmqctl add_user postal passw0rd\r\n[user]$ rabbitmqctl set_permissions -p \/postal postal \".*\" \".*\" \".*\"<\/pre>\n<h2>7. Install and configure Postal Mail Server<\/h2>\n<p>Now that we finished with the prerequesities we can move on to the actual Postal setup. First, we&#8217;re gonna start with creating a user(account) named &#8216;postal&#8217;<\/p>\n<pre>[user]$ sudo useradd -r -m -d \/opt\/postal -s \/bin\/bash postal\r\n[user]$ sudo setcap 'cap_net_bind_service=+ep' \/usr\/bin\/ruby2.3<\/pre>\n<p>Next, clone the source code from the Postal GitHub repo and add a soft link to the Postal binary file:<\/p>\n<pre>[user]$ sudo -i -u postal git clone https:\/\/github.com\/atech\/postal \/opt\/postal\/app\r\n[user]$ ln -s \/opt\/postal\/app\/bin\/postal \/usr\/bin\/postal<\/pre>\n<p>To configure Postal, you need to install bundler and procodile. Do that with the following command:<\/p>\n<pre>[user]$ sudo gem install procodile bundler<\/pre>\n<p>To finish with all the installs, switch to the portal user:<\/p>\n<pre>[user]$ su - postal\r\n[user]$ postal bundle \/opt\/postal\/app\/vendor\/bundle\r\n[user]$ postal initialize-config\r\n[user]$ postal initialize<\/pre>\n<p>And open your postal.yml file from \/opt\/postal\/config and update it according to your setup.<\/p>\n<p>Run Postal in the background with the following command:<\/p>\n<pre>[user]$ postal start<\/pre>\n<h2>8. Create Postal Admin User<\/h2>\n<p>To create the first Postal administrator account, run make-user:<\/p>\n<pre>[user]$ postal make-user<\/pre>\n<p>Postal User Creator<br \/>\nEnter the information required to create a new Postal user.<br \/>\nThis tool is usually only used to create your initial admin user.<\/p>\n<p>E-Mail Address : admin@linuxhostsupport.com<br \/>\nFirst Name : LinuxHostSupport<br \/>\nLast Name : Admin<br \/>\nInitial Password: : *********<\/p>\n<p>User has been created with e-mail address admin@linuxhostsupport.com<\/p>\n<p>Again, use a strong password!<\/p>\n<h2>9. Check Postal Running Status<\/h2>\n<p>Now your Postal is successfully installed, configured and running. Check its status with the following command:<\/p>\n<pre>[user]$ postal status<\/pre>\n<p>Make sure all services are running and working properly.<\/p>\n<h2>10. Configure Nginx with Postal<\/h2>\n<p>Postal comes with its own configuration file. You can copy the cfg file to your nginx directory. Replace the default configuration file or create a new one.<\/p>\n<pre>[user]$ cp \/opt\/postal\/app\/resource\/nginx.cfg \/etc\/nginx\/sites-available\/default<\/pre>\n<p>By default, Postal only works with SSL. You can use a self-signed SSL.<\/p>\n<pre>[user]$ sudo mkdir \/etc\/nginx\/ssl\/\r\n[user]$ sudo cd \/etc\/nginx\/ssl\/\r\n[user]$  openssl req -x509 -nodes -newkey rsa:4096 -keyout postal.key -out postal.crt<\/pre>\n<p>Finally, restart nginx for the changes to take effect.<\/p>\n<pre>[user]$ sudo service nginx reload<\/pre>\n<p>Now you can access the Postal dashboard via https. Use the details from step 8.<\/p>\n<p>That is it. The Postal installation is now complete.<\/p>\n<p>Of course, you don\u2019t have to do any of this if you use one of our\u00a0<a href=\"https:\/\/linuxhostsupport.com\/software-installation.html\">Software Installation Services<\/a>, in which case you can simply ask our expert Linux admins to install Postal for you. They are available 24\u00d77 and will take care of your request immediately.<\/p>\n<p><strong>PS<\/strong>.
