Configuring Email Security
Anti-Virus
ePrism provides an optional virus scanning service. When enabled, all messages (inbound and
outbound) passing through the ePrism Email Security Appliance can be scanned for viruses.
ePrism integrates the Kaspersky Anti-Virus engine, which is one of the highest rated virus
scanning technologies in the world. Virus scanning is tightly integrated with the mailer for
maximum efficiency.
Viruses can be selectively blocked depending on whether they are found in inbound or outbound
messages, and attachments are recursively disassembled to ensure that viruses cannot be concealed.
When a virus-infected message is received, it can be deleted, quarantined, or the event can be
simply logged. Quarantined messages may be viewed, forwarded, downloaded, or deleted.
Quarantined messages can also be automatically deleted based on age.
By default, any email attachments that cannot be opened and examined by the mail scanner
because of password-protection are quarantined. This feature prevents password-protected zip files
that contain viruses or worms from being passed through the system.
Virus pattern files are automatically downloaded at regular intervals to ensure that they are always
up to date. Notification messages can be sent to the sender, recipient, and mail administrator when
an infected message is received.
Licensing Anti-Virus
To enable virus scanning after the 30-day evaluation period, you must purchase and install a license
for each system. See “License Management” on page 184 for more information on adding licenses.
