However, these services may not be suitable for storing personal and professional confidential data. It is unsafe to use online cloud storage service for business. There is a solution to this problem. PEPS is a platform for the exchange of mail and files based on end-to-end encryption. Data is encrypted and decrypted on your computer (the client) but not on the server. In this case, the server never sees unencrypted data. This gives the confidence that even if the server is hacked, the hackers won&#8217;t get access to your correspondence or any data that is stored on the server. <!--more--><\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">This tutorial consists of information about the basic functions, the principle of installation and operation of this software.<\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\"><b>Prerequisites:<\/b><\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">PEPS is distributed as a Docker container to simplify the installation.<\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\"><b>Docker<\/b> is an open-source project that automates the deployment of applications inside software containers, by providing an additional layer of abstraction and automation of operating-system-level virtualization on Linux.

Now you have to set up the domain properly (use real SSL certificates, configure DNS and others).<\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">Let`s start with DNS. The DNS configuration will differ depending on your provider of the domain names and also if you use a custom interface for configuring your DNS records.<\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">You have to set up A and MX records. For example, example.com is placed on:<\/span><\/p>\n<pre lang=\"php\"><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">mail.example.com.   10799   IN   A    your_server_ip\nmail.example.com.   10799   IN   MX example.com.<\/span><\/pre>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">Your Droplet name must be mail.example.com. You can rename Droplet easily. Click on Droplet name to see the details, select Settings tab, press Rename tab. It can take some time so you have to wait till the records will be updated.<\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">You can also setup the additional records. Use MXToolBox test: this service will check your domain settings.<\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">As usual, DNS records update can take up to 48 hours.<\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">Important: If you cannot send or receive email from external domain after you finished configuring PEPS, double check your A and MX records. Perhaps a mistake was made when creating records or these records may not be updated yet.<\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\"><b>Step 5 &#8211; SSL certificate setup<\/b><\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">To install the SSL certificate you have to copy files for your domain to PEPS directory (you received them from the certification center).<\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">You may use the following command to copy files:<\/span><\/p>\n<pre lang=\"php\"><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">scp server.key server.crt your_server_ip:\/etc\/peps\/<\/span><\/pre>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">where your_server_ip &#8211; IP of your server.<\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">Check whether your browser can open https:\/\/example.com without SSL error. Try to open it using an incognito tab in your browser.<\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\"><b>Step 6 &#8211; Testing<\/b><\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">To create more users you need to go to PEPS control panel with Administrator access and go to the \u201cPeople\u201d panel. Select \u201cUsers\u201d and click on \u201cNew User\u201d function button.<\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">To check email try to send a letter to any Inbox and receive a response to the letter. If the letter is sent, but no response, then most likely the problem is in DNS records. They might not be updated or contain errors. Go back to step 4: Domain settings. Do not forget to check the receive email from the user.<\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\"><b>Conclusion<\/b><\/span><\/p>\n<p><span style=\"font-family: Ubuntu, sans-serif; font-size: 12pt;\">Congratulations!
