Since version 10.4 of the Plesk panel, you no longer have to book the Power Pack to use Spamassassin and the Application Pack. Since version 10.4 these have been part of the standard license.
In addition to Tomcat, Coldfusion, MSSQL / PostgreSQL and the Helpdesk, the following new features are now available in the new Power Pack for Plesk:
[New] Parallels Plesk Mobile Server Manager ( www.parallels.com/products/plesk/power-pack/plesk-mobile-server-manager/ )
[New] Unity one (2-domain limit) ( www.unitymobile.com/Parallels-Plesk )
[New] Kaspersky Anti-Virus for Plesk (5-mailbox limit)
The changes apply to all of our root servers as well as to all of our virtual servers.
