Email has become a mission critical network application for every type and size of business. Spammers and attackers are using email as the most popular delivery mechanism to flood users with unwanted mail (spam) and attack corporate resources or steal information by infecting email messages with viruses, worms, Trojans, and other harmful applications.
By implementing the AdaptiveMobile PolicyFilter (Email), operators are able to:
• Protect their network from being seen as a source of spam and being blacklisted by companies and other service providers. Just one infected user can potentially stop every subscriber from sending email as they share the same public IP addresses;
• Identify and respond to infected users through the AdaptiveMobile Virus Recovery Engine;
• Limit unnecessary network usage from unwanted messaging;
• Offer different classes of security protection on mobile email services, depending upon corporate requirements or customer sign-up.
The PolicyFilter (Email) can be implemented to provide inbound and outbound filtering and incorporates the following features:
• Virus and Spam detection can be implemented with a wide choice of third party engines – including automatic updating of Virus/Spam definitions;
• Duplication of messages allows admin review of blocked or suspect items;
• Notification by email, MMS, or SMS when Spam/Virus bearing messages are blocked;
• Reporting function allows analysis of email volume, emails blocked, filtered/permitted;
• Identification and blocking of malicious senders by MSISDN. Infected subscribers can be refused access to SMTP;
• Maximum number of recipients (per SMTP server) can be set, thereby limiting Spam attempts;
• Maximum Messages size setting allows you to restrict the size of messages that can be sent;
• Throttling allows you to specify a minimum time-lag between TCP connections, determining the rate at which messages can be sent, and discouraging Spamming.
