MailScan has its own inbuilt Anti-Virus, '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.
All incoming and outgoing messages are scanned
for abusive 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.
policies (pre-defined words and phrases) are dynamically updated from the Internet
at regular intervals, along with normal Anti-Virus and Policy 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.
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.
Scan HTML Messages.
It forcibly scans HTML messages (not having attachments),
to prevent script viruses (like Bubble-boy) from entering your network.
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 Anti-Virus and Policy
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.
Easy and convenient Administration.
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.
Get Up-to-date names of Viruses
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.
Every action of MailScan is properly
logged. The administrator can control size of Log files and create backups of
old Log Files.
