IIJA offers E-Mail Defense service
to protect the users from unwanted spam messages. The
same service is available to customers regardless of
their sizes and e-mail environment.
One customer was satisfied with
the day-to-day operation of their e-mail server but
was facing challenges with spam messages.
Mail environment:
Total number of messages per day: 110,000 messages
(80% of which were viruses or spam)
Total number of employees: 3,000 employees
Firewall and e-mail server operated by the customer
Issues:
Large volume of incoming messages require higher
end firewall and e-mail server
Large amount of network bandwidth wasted
Delivery delay caused by inability to handle large
volume of messages
Requires regular investment in software and hardware
upgrades to stay up-to-date with the latest threats
such as phishing
IIJA offered the following solution
to solve customer's spam problem, as well as to ease
heavy load on the infrastructure.
E-Mail Defense service through MXLogic, an IIJA
partner provider (only requires a change in MX record)
Includes 3 virus scanning engines in addition to
the spam filter
FailSafe Spool function stores up to 5 days of messages
in the event of e-mail server failure
Each user has an access to their own web management
console
IIJA's Email Defense service
only requires a modification in the MX record to route
the e-mail destination. There is no need to change the
network configuration on the customer's end.
Out of a total 110,000 e-mails, roughly 90,000 (approximately
80%) were viruses or spam. These unnecessary data
no longer reached the perimeter firewall or the
e-mail server.
Freed up resources for the Internet connection,
firewall and e-mail server.
Source IP address restrictions eliminate the chances
of e-mail servers used for open SMTP relay.
Reduction in hardware and software investment and
maintenance expenses.
High filtering accuracy attributed to the latest
filtering technology.
Up to 5 days of unlimited messages can be spooled
in a case of e-mail server failure.
Upon recovery of the e-mail server, mail inflow
is controlled to prevent the e-mail server overload.
Each user has access to his own personal web interface
to check quarantined messages. The setting is configurable
by each user.
MX Logic's industry leading spam
filtering technology eliminated spam messages with high
accuracy. The customer also benefited from reduction
in Internet connection usage and processing load on
the corporate e-mail servers.
