Antivirus & Antispam Protection

Spam (unsolicited commercial e-mail) accounts for 45% of all messages and is rapidly increasing. 1 in 150 messages contains a virus, costing many billions of dollars around the world every year. Surveys have shown that removing 1 virus from 1 PC costs over $600. Removing a virus infection from a server costs over $50,000.

At Quality Host Online, we take this very seriously. Therefore we use the latest AntiVirus and AntiSpam filters on our servers. The filtering service consists of MailScanner, SpamAssassin, ClamAV, DCC, Vipuls Razor, SARE and Dictionary Attack ACL.

Each email is checked by this filtering service which determines if the email is from a known spam source and if it contains any known viruses. The service gets information from many spam detecting and filtering networks so it can perform reliably. We catch around 95% of all incoming spam and over 98% of all viruses.   Filtering Software installed: http://www.mailscanner.info

SpamAssassin SpamAssassin is a mail filter to identify spam. It is an intelligent email filter which uses a diverse range of tests to identify unsolicited bulk email, more commonly known as Spam. These tests are applied to email headers and content to classify email using advanced statistical methods. In addition, Spam Assassin has a modular architecture that allows other technologies to be quickly wielded against spam and is designed for easy integration into virtually any email system. SpamAssassin Advantage: SpamAssassin's practical multi-technique approach, modularity, and extensibility continue to give it an advantage over other anti-spam systems. Due to these advantages, SpamAssassin is widely used in all aspects of email management. You can readily find Spam Assassin in use in both email clients and servers, on many different operating systems, filtering incoming as well as outgoing email, and implementing a very broad range of policy actions. These installations include service providers, businesses, not-for-profit and educational organizations, and end-user systems.
