| Integrated
Firewall: |
| The
most common action of IT administrator to improve e-mail
security is often put organization mail server behind
firewall, which only protects mail server from external
network attack. NextMessage goes one extra step by integrating
stateful packet-filtering firewall, which filters all
traffics to the system to prevent both internal and external
malicious traffic attacks. |
| IDS
(Intrusion Detection System) and Bandwidth Management |
| Working
behind the scene, NextMessage IDS sub system monitors
all traffic patterns coming through the system looking
for suspicious DoS pattern. If found, NextMessage IDS
notifies integrated bandwidth management to adjust bandwidth
for certain suspicious traffic down to the safety level. |
| SMTP
filtering: IP, Host , and Address Screening |
|
NextMessage provides the capability to screen and prevent
certain addresses and domains from connecting to or sending
email through SMTP sub system. It's also possible to allow
connections from specific IP addresses while screening
all others. |
| SMTP
Authentication |
|
NextMessage contains a number of options related to whether
or not a connecting user has authenticated their mail
session. Local users can be required to authenticate before
sending email, a global authentication password can be
specified, and more. |
| Relay
Control |
| With
NextMessage, you can define how your server reacts to
attempts to relay mail. When a message arrives at NextMessage
server that is not from or to a local address. Third-party
servers are often used by spammers to hide their tracks,
and can result in your server being black-listed as an
Open Relay. NextMessage provides a high level of protection
against this activity. |
| Reverse
Lookup |
| NextMessage
can be configured to query DNS servers to check the validity
of the domain passed in the SMTP commands. When performing
these reverse lookups NextMessage will attempt to acquire
all of the MX and A record IP addresses for the given
domain. Then the IP address of the machine making the
connection is compared to this list in an attempt to determine
whether the sender might be forging their identity. |
| Virus
|
| Integrating
seamlessly with NextMessage, NextMessage Anti Virus helps
ensure that your email arrives totally free from e-mail
based viruses. Anti Virus for NextMessage is equipped
with an automatic updater so that its virus signatures
can be updated at scheduled intervals. Beside integrated
Virus Filter, NextMessage is working seamlessly with external
Virus scanner like Trend Micro or Symantec. |
| Secure
Socket Layer (SSL) Support |
| Secure
Socket Layer (SSL) support provides authentication and
encryption for your web mail, SMTP, POP, and IMAP protocols—it
provides server authentication, data encryption, and optional
client authentication for TCP/IP connections. Further,
because SSL is built into all current major browsers,
simply installing a valid digital certificate on your
NextMessage appliance will activate the connecting browser’s
SSL capabilities when connecting to NextMessage web mail. |
| Spam
Block |
| This
security feature allows you to specify RBL maps server
who maintain black lists of servers known to relay spam.
When enable, the RBL list is queried each time someone
tries to send a message to NextMessage server. If the
connecting IP address is blacklisted by any RBL maps,
the message is refused or flagged as spam by NextMessage. |
|
Smart Spam Guard Filter |
Throughwave's
Spam Smart Guard technology delivers mail to your
inbox only if mail come from someone that you know. Smart
Agent by
nature, it scans the message and tracks back to make sure
that someone
who sent mail to you is someone real, not a spam mail
robot. |
