Mattermost for Plesk Premium Email – The Perfect Match

Many of the world’s leading high-security enterprises work better with Mattermost by connecting people, tools, and automation across tens of thousands of users. And that’s why Mattermost integrates with Plesk Premium Email, powered by Kolab, acting as a secure chat module for the web client. With this union, teams are not only more connected and productive – they thrive!

Mattermost is supported on Plesk 17.8 or later, installed on the following Linux distributions: CentOS 7, Debian 8 and 9, Red Hat Enterprise Linux 7, and Ubuntu 16.04 and 18.04.

It’s also worth noting that, additionally, Mattermost has some requirements when working with Plesk. The domain must be secured with a valid SSL certificate, and NGINX must be enabled in proxy mode. Also, on CentOS 7 and RHEL 7, it’s required to install Postgres 9.4 on the system that is incompatible with the PostgreSQL component.

Plesk’s self-hosted online office brings people, discussions, bots, tools, and files together. This shared workspace lets groups collaborate in real-time throughout the project lifecycle. Also, Mattermost’s self-hosted approach provides modern communication benefits without sacrificing privacy, giving more control to teams.

Why is Email Security so Important?

When was the last time you checked your email security? Are your mailboxes and personal data protected enough? The unprecedented situation we’re all currently going through is affecting online businesses worldwide. And according to Cloudflare, online threats rose by six times their normal levels in the early weeks of the pandemic outbreak. Based on the 2020 Data Breaches Investigation Report by Verizon, 28% of the breach victims were small businesses. Which translates into an increasing cybersecurity risk.

Strong email security is crucial to safeguard your business and keep it running, during COVID-19 times more than ever. In this article, we’ll guide you through some ways to spot malware and how to keep your email and data secured.

Most Common Email Threats and How to Block Them

There are several reasons why you should protect your server against cyber threats. And of course, there are also many ways you can secure your self-hosted email using different security sever tools. Let’s go through the most common email threats and what we can do to block them.

Malware

Malware often accompanies spam and phishing attacks. Viruses, trojans, ransomware, and all sorts of malware use email to gain access to personal and corporate email accounts. And once they access your server, there’s not much you can do about it. Hackers use malware to steal personal information, such as sensitive data like credit cards and infect computers, to use them to mine cyber currency.

But it’s easy to block malware and stop it from damaging your server by installing effective anti-virus solutions. ImunifyAV and Kaspersky Antivirus for Servers are two power-tools that can detect any malicious file, eliminate it, and monitor and control your security.

Spam

Some might think that spam is harmless. However, that’s not even near reality as spam brings severe risks to your data and server security. For instance, email bombing is a very popular form of spam that involves sending massive amounts of messages to your address. Because if you start receiving a waterfall of emails that flood your inbox, it might cause a distraction to see the real damage. And by the time you notice something’s wrong, it might be too late to solve it.

Spam not only causes headaches when receiving but also sending. One of the most significant problems when having your account hacked is facing a bad reputation. Using solutions such as Warden Anti-spam and Virus Protection or Plesk Email Security for outbound anti-spam and anti-virus ensures that your server doesn’t send spam. And that no spammer can get access to your server, damaging your reputation.

Weak passwords

Choosing the right password can wholly become a tricky task that can end up exposing your server to all types of cyber-attacks. If the password is too simple, it will most probably be easy to guess. And if, on the contrary, the password you pick is too hard, chances are you will forget it in an instance.

Installing a multi-factor authentication such as Google Authenticator enables you to log in to your server without using passwords. Which reduces the risk of getting hacked. If you want to learn more about authentication schemes in Plesk, you can also read this blog post.

Let’s have a look at two alternatives for protecting your email hosted on Plesk – Plesk Email Security and MagicSpam.

What You Need to Know About the MagicSpam Extension

MagicSpam has also been for many years one of the most used third-party extensions for email protection on Plesk. This anti-spam software installs directly on the mail server or control panel and simplifies spam protection.

However, we have an important announcement regarding the MagicSpam extension. Because, from the end of October 2020, MagicSpam will no longer be listed in the Plesk Extension Catalog. This means that MagicSpam users will still be able to use the extension on the Plesk platform but will no longer enjoy the benefits of using an official Plesk extension. That is, for instance, 100% compatibility with the Plesk platform, affordable prices, and most importantly, 24/7 support from the Plesk support team.

But there’s no reason to panic. If you are a current MagicSpam user, we recommend that you uninstall MagicSpam immediately and replace it with Plesk Email Security – our complete, fully supported, and budget-friendly extension.
