Spam-and-Virus Protection
LiveOffice Email Continuity provides advanced spam-and-virus protection to help safeguard mission-critical email communications, even when in deactivated mode. This level of protection is critical when you activate Email Continuity, so your Exchange environment and end users are protected from spam (and the viruses they often contain). Email Continuity employs multiple layers of protection to evaluate, detect and block spam emails and dangerous viruses, including:
Blacklisting
Blacklisting scans the Internet for email traffic sources that are sending unsolicited commercial email. Once a site is identified as a spam source, it is "blacklisted," and all emails sent from that source are blocked from reaching you. Email Continuity maximizes the effectiveness of this technique by combining the best commercial and proprietary "blacklist" technology to shutout spam messages. This unique approach, combined with our proprietary, multilayer screening methodology, enables us to deliver the highest levels of spam-and-virus protection.
Profiling and Rules-Based Scoring
LiveOffice's spam-and-virus protection solutions analyze inbound communications to identify the characteristics of new spam emails. These profiles are used to update the Email Continuity spam-and-virus solution. The system then creates models of known spam communications and generates filters to block them from reaching you.
Profiles from messages identified as spam are permanently incorporated into the Email Continuity spam filter and used to identify and mark future communications as potential junk email. These profiles are further ranked by a proprietary scoring system, enabling Email Continuity to identify and block emails that are clearly spam, while allowing legitimate messages to pass through to the intended recipients.
Reverse DNS Lookup
Reverse DNS lookup checks the Internet address of the server sending emails to verify that it is a legitimate message source. Spammers typically use multiple networks to send emails. With reverse DNS lookup, Email Continuity notes the sender's address on inbound communications to identify those that are not legitimate, then immediately blocks their incoming spam.
Multilayer Virus Scanning
LiveOffice maintains very close relationships with a number of antivirus software partners to quickly identify and block new virus releases. In addition, Email Continuity employs sophisticated recognition technology that identifies and blocks specific types of virus-laden email attachments.
