Key Features of MailScan

A. Web Based Administration MailScan captures all the data with the help of its MailScan Exchange Connector integrated with Exchange, performs virus and content scanning and blocks Spam mails and then delivers the content to the mail server, thereby providing security on a "Real-Time" basis.

B. Virus Scanning MailScan has its own inbuilt AntiVirus, 'eScan', which is integrated with the software in a DLL format. Virus infected attachments are disinfected and sent to their destination. Non-removable virus infected attachments, are either deleted or quarantined. If MailScan detects a Word or Excel attachment that contains an infected macro, it removes the virus from the attachment. Clean Macros are not removed from the document.

In case of any virus infection, appropriate warning messages, with the Virus Name, Action taken, and e-mail details, are sent to the e-mail Sender, the Recipient, and the Mail-Server Administrator

C. Content Scanning All incoming and outgoing messages are scanned for offensive words and/or phrases, which are pre-defined by the Security Policy Administrator of MailScan. If such words occur, warning messages can optionally be sent to the Administrator, the sender and the recipient.

Global Content-Control policies (pre-defined words and phrases) are dynamically updated from the Internet at regular intervals, along with normal AntiVirus and Policy updates

D. Automatic Updates MailScan has self-learning and automatic detection capabilities that recognize Internet connectivity. When MailScan detects an Internet connection, it automatically connects to MicroWorld's FTP server to check for and download Updates. With this feature (that works on dedicated as well as dial-up lines), all MailScan users across the world receive updates on a regular basis. Both Attachment filter rules and AntiVirus Updates are downloaded.

Automatic updates can be via FTP or HTTP. Proxy and Firewall (Passive FTP) support is provided. Broken FTP Updates can be resumed from breakpoint.

E. Customized Messages Customized Virus Warning, Content Warning and Reserved Attachments Warning can be sent to the Administrator, the sender and the recipient.

Warning messages can be in text or HTML format. They can be in English or any other language

F. Forcibly Scan HTML Messages It forcibly scans HTML messages (not having attachments), to prevent script viruses (like Bubble-boy) from entering your network.

G. Malicious Attachments Deletion Provides an option to forcibly delete known malicious attachments (Trojans and worms) at the gateway level itself based either on the file type or extension, size of attachment, etc. This list is dynamically updated from the Internet at regular intervals, along with normal AntiVirus and Policy updates.

H. Heuristic Scanning MailScan's heuristics scanning feature ensures that 90% of unknown viruses are automatically detected, much before the world even gets to know about these viruses. Unknown virus infected files display suspicious behavior. Such files and attachments are detected by MailScan's heuristics engine and are quarantined to a safe directory.

I. Easy and Convenient Administration MailScan provides an easy and convenient way of administrating Rule-Sets and Security Policies. Users can install MailScan and use the default settings. All threats, updates, security policies, and rule-sets are "automatically updated" from the Internet, without any user-intervention.

J. Get Up-to-date names of Viruses via Email Whenever MailScan automatically downloads updates, the administrator is informed via e-mail about the time and date of update, number of files downloaded and a list of viruses cleaned by the update. Virus policy updates are done on a daily basis.

K. Extensive Logs Every action of MailScan is properly logged. The administrator can control size of Log files and create backups of old Log Files.
