Press Release Body: Rack-Soft launched 4PSA Clean Server 4, the next generation
email and file system antivirus for Plesk servers, based on the 4Grid technology.
The software introduces distributed scanning, delivery policies and advanced
antivirus control features. 4PSA Clean Server uses the award winning ClamAV
antivirus engine.

4PSA Clean Server 4 solves all email antivirus scanning issues that Plesk
administrators face today. With a traditional antivirus, email scanning is performed
on the hosting server. As the scanning process is CPU intensive, regular processes
serving HTTP or Database are affected, leading to sub-pair performance. On a hosting
server using an old generation antivirus, high email flow can lead to Denial of
Service or delayed email delivery.

To solve some of the problems associated with host level email scanning, providers
deploy specialized email filtering appliances in front of the hosting servers. These
usually introduce single points of failure, can scan a limited number of emails,
hardly integrate in an automated environment, and are not economically efficient.

4PSA Clean Server 4 introduces a new approach to solve these issues by clustering
the scanning processes. The product can be installed on one server like a
traditional antivirus and when the number of servers increases, the hosting company
can introduce specialized scanning nodes that handle email scanning for the entire
infrastructure. Scanning requests are distributed automatically between scanning
nodes and email delivery is not affected even when a hosting machine is flooded with
emails.

The product is based on the proprietary 4Grid, an innovative technology born to
allow providers to create service delivery clouds. "4PSA Clean Server 4 is our first
public release of a product based on 4Grid framework. Together with our customers,
we tested the new version in large environments with more than two hundred Plesk
hosting servers. Our testing partners were excited to see that the product took the
scanning load from the hosting servers, allowing these to better answer to requests
and serve more customers. With 4PSA Clean Server, hosting businesses are no longer
limited by email volume", said Bogdan Carstoiu, Rack-Soft’s General Manager.

4PSA Clean Server 4 is compatible with Linux/Unix servers running Plesk 8.2.0 and
newer versions. The product is also available in Virtuozzo installation templates
format, simplifying deployments on virtualized servers. 4PSA Clean Server 4 provides
the best TCO in business with server license prices starting with 99USD.
