What's New in Plesk 12

We are happy to announce that Plesk 12.0 is now publicly available!

The goal of this release was to make Plesk a better, more reliable, and more secure tool for both Web hosts and Website owners.

Please download and try Plesk 12.0. Your feedback is greatly appreciated!

Here is a closer look at the changes.


Protection from Outgoing Spam and Other Mail Improvements

Plesk 12.0 introduces numerous enhancements in mail:

Administrators can protect server IP addresses from being put into spam blacklist due to outgoing spam. Plesk offers a solution for all three major modern threats: stolen SMTP/POP3 accounts, malicious mass mailing web scripts and hacked customers' system accounts.

Each of these threats can be dealt with by limitation of outgoing email messages per hour. Limits can be defined for a mailbox (individual mailboxes), for a domain (all customer's mailboxes and website on a domain), and for a system account (all mailboxes and websites from all customer's domains). The limits can be set at the server level and for individual mailboxes or customer accounts. Learn more.

Protection from email interception. Malicious users can set up domain names that are identical to the domain names of popular online stores and other resources. In certain cases, this enables those users to receive email messages sent by your customers to the legitimate companies. To protect your customers from this type of scam, you can prohibit the setup of domain names that are already registered and belong to existing companies. There is a prefilled list containing a hundred popular domains. Learn more.

Now users can enable and disable mail service for individual domains and adjust other mail settings. Learn more.

Also, administrators and resellers can switch on and off the mail service on subscriptions by means of service plans.


WordPress Toolkit

Plesk 12.0 introduces WordPress Toolkit, a powerful tool for managing APS- and non-APS-based WordPress installations. The toolkit enables server administrators, resellers, and customers to manage multiple WordPress installations, plugins, and themes from a single point of entry. Users can install, update, and remove WordPress installations, activate and remove plugins and themes.

WordPress Toolkit also addresses the WordPress security matters. Installation of WordPress via APS now immediately provides customers with secure WordPress instance out-of-the-box, applying recommended security improvements during the installation. You can scan selected WordPress installations to see how secure they are and apply selected security improvements. Since some of the security improvements may affect the functioning of WordPress, its plugins or themes, these improvements can be rolled back if something goes wrong.

Server administrators can control the availability of WordPress Toolkit for customers by means of service plans. The availability of security scan (including application and rollback of security enhancements) is managed by a separate option.

The availability of WordPress Toolkit depends on your license key. To check whether the license key supports it, go to Server Management > Tools & Settings > License Management, and see if there is the line "WordPress Toolkit On". If such a line is missing, your license key does not support it.

Note: WordPress Toolkit requires PHP 5.3 or later to be installed on the server.

Usability and Convenience

Plesk 12.0 makes account management complete for server administrators. Customer accounts can be moved from one reseller to another, and customer accounts can be converted to resellers and back. Custom comments for accounts and domains help to remember important nuances and simplify daily routines. Troubleshooting and assistance tasks become easier for administrators, who can work on behalf of their resellers, in addition to the previously available option to work on behalf of their customers.

Site management became easier for administrators in Power User Mode, resellers, and customers. Users can now select the "All subscription" option in the subscription or webspace selection menu, and manage all their sites from a single page. Also, the users of reseller accounts, who do not resell anything but only manage their own sites, can access a simplified site management interface.

Mobile-friendly interface: The tabbed user interface of hosting customers and Plesk administrators (when in Power User mode) automatically adjusts to the size of the screen on mobile devices.

Now users can restore individual reseller accounts, customer accounts, subscriptions, domains, DNS zones, mailboxes, mailing lists, databases, files and directories of a site, and SSL certificates. These are restored without any change in other content and without a need to hack into Plesk's internal backup format. Learn more.


Multi-Language Support

Plesk is now available in 21 language, including English, German, Spanish, French, Italian, Japanese, Dutch, Russian, Chinese Traditional, Chinese Simplified, Polish, Portuguese, Brazilian Portuguese, Korean, Danish, Norwegian, Swedish, Finnish, Turkish, Greek, and Ukrainian.


Performance Improvements

The performance of IIS-based servers with large numbers of subscriptions was improved. The figure below illustrates how much faster Plesk works now. It shows the time it takes Plesk to create a subscription depending on how many subscriptions are already present on the server. The spikes on the graph show when daily maintenance script was running, increasing server load.

As you can see, with these optimizations Plesk 12.0.12 shows a 2.5x-4x performance boost compared to Plesk 11.5.
