Looking for email anti-spam and email security?
GFI MailDefense Suite, comprising GFI
MailEssentials and GFI MailSecurity, ships at the lowest price on the
NEW! – SpamRazer: An additional
The latest version of GFI MailEssentials
includes a new, second anti-spam engine, SpamRazer, which provides a
second layer of protection. It has been designed to be very simple to
use and due to frequent updates, SpamRazer will require no tweaking or
training for it to be fully effective whilst filtering the latest spam
attacks such as NDR spam, CNN spam, MSNBC spam and many more. Not only
will administrators benefit from out-of-the-box filtering but they will
not need to tweak GFI MailEssentials each time a new attack is out. With
SpamRazer filtering, IP reputation filtering, Bayesian and other
advanced anti-spam technologies, the spam capture rate is well over 98%.
GFI MailEssentials has a market-leading low rate of false positives
thereby ensuring that good and important emails are not deleted.
NEW! – Precise real time dashboard
GFI MailEssentials also ships with a precise,
real-time dashboard that gives administrators a graphical view of the
software’s status and as well as the server’s email flow. Components
shown on the dashboard are the status of key services provided by GFI
MailEssentials, statistics of email flow and blocked spam and also
NEW! – Improved performance
GFI MailEssentials hooks into Exchange server
at the SMTP protocol level and the Exchange server does not need to
download all the email before the software can determine whether an
email is spam or a genuine message. This feature saves bandwidth and
NEW! – Inbuilt spam reporting
Administrators can now use GFI
MailEssentials' reporting function to send a daily report to the users
within the organization that shows how many emails were received by that
individual and how many emails are identified as spam and filtered. This
snapshot of email traffic shows the end-user how effective the anti-spam
engine is and that the bulk of spam sent to him or her was successfully
captured. The report also gives a full list of those emails identified
and filtered as spam.
IMPROVED! – Eliminate hard to catch NDR,
MSNBC and CNN spam!
With spammers controlling tens of thousands
of zombie machines, these large botnet armies have become one of the
leading sources of spam. The Botnet/Zombie check in GFI MailEssentials
eliminates hard to catch attachment spam such as image spam, PDF spam,
Excel and ZIP spam. The attachment spam check filters this attachment
spam quickly, efficiently and with a very low rate of false-positives.
GFI MailEssentials uses two anti-spam filter engines and a variety of
technologies such as Bayesian Filtering and IP reputation filtering to
keep Non-Delivery Report (NDR), CNN spam, MSNBC spam and many more at
Server-based anti-spam and anti-phishing
GFI MailEssentials is server-based and
installs on the mail server or at the Gateway, eliminating the
deployment and administration hassle of desktop-based anti-spam and
anti-phishing products. Desktop-based software involves training your
users to create anti-spam rule sets, and subsequently users have to
spend time updating these rules. Besides, this system does not prevent
your server message stores from filling up with spam.
Bayesian filtering technology
Bayesian filtering is widely acknowledged by
leading experts and publications as the best way to catch spam. A
Bayesian filter uses a mathematical approach based on known spam and ham
(valid email). This gives it a tremendous advantage over other spam
solutions that just check for keywords or rely on downloading signatures
of known spam. GFI’s Bayesian filter uses an advanced mathematical
formula and a dataset which is ‘custom-created’ for your installation:
The spam data is continuously updated by GFI and is automatically
downloaded by GFI MailEssentials, whereas the ham data is automatically
collected from your own outbound mail. This means that the Bayesian
filter is constantly learning new spam tricks, and spammers cannot
circumvent the dataset used. This results in a 98+% spam detection rate,
after the required two-week learning period. In short, Bayesian
filtering has the following advantages:
Downloads updates to spam profile database
- Looks at the whole spam message, not just keywords or known spam
- Learns from your outbound email (ham) and therefore greatly
reduces false positives
- Adapts itself over time by learning about new spam and new valid
- Dataset is unique to your company, making it impossible to
- Multilingual and international.
GFI MailEssentials can download updates to
the Bayesian spam profile database from the GFI site, ensuring that it
recognizes the latest spam and spamming techniques. GFI maintains the
spam profile database by working with a number of spam collection
organizations that continually supply spam samples.
Protect your users against the menace of phishing emails
GFI MailEssentials’ anti-phishing module
detects and blocks threats posed by phishing emails by comparing the
content of the scam with a constantly updated database of blacklisted
mails, thereby ensuring all the latest phishing emails are captured. As
extra protection, it also looks for typical phishing keywords in every
email sent to your organization.
Sort spam to users' junk mail folders
GFI MailEssentials gives you the flexibility
to choose what to do with spam. You can delete it, move it to a folder,
forward the spam mail to a public email address or folder, or send it to
individual customizable folders (for example, a “junk mail” folder) in
the end-users’ inboxes. This allows users to easily review mail that has
been flagged as spam.
List server for newsletter lists and discussion lists
A list server is the best method for
distributing company newsletters, since it automates the process of
allowing users to subscribe and unsubscribe (required by anti-spam
regulations). However, until now, list servers have been expensive and
difficult to administer and they did not integrate with Exchange Server.
GFI MailEssentials integrates with Exchange and can use Microsoft Access
or Microsoft SQL Server as the backend. Both newsletter lists and
discussion lists are supported.
Easy tuning of the Bayesian engine via public folders
Administrators can easily tune the Bayesian
engine by dragging and dropping spam or ham to the appropriate public
folder. GFI MailEssentials learns from the spam and ham that it picks up
from these folders and further improves its spam detection rate.
Administrators can control access to this feature through the use of
Public Folder security.
Allow users to whitelist or blacklist via public folders
GFI MailEssentials allows users to whitelist
or blacklist senders simply by dragging and dropping the appropriate
mail to a public folder. This gives users more control and reduces
administration. Administrators can control access to this feature
through the use of Public Folder security.
Email header analysis and keyword checking
GFI MailEssentials intelligently analyzes the
email header and identifies spam based on message field information. It
detects forged headers, encoded IPs, spam mutation, spam sent from
invalid domains, and more. It also enables you to configure keywords to
check for spam using keyword checking.
Third party DNS blacklists (DNSBL) checking
GFI MailEssentials supports DNS blacklists
(real time black hole lists), which are databases of known spammers. If
the sending mail server is on one of those lists, it marks the email as
spam. GFI MailEssentials supports popular third party blacklists such as
ORDB, SpamHaus, Spamcop and also enables administrators to configure
custom RBL servers.
Support for multiple third party SURBL servers
GFI MailEssentials checks email content
against SURBL servers. Administrators can configure multiple SURBL
servers, add their own and also define the priority of which server
should be checked first.
Automatic whitelist management reduces false positives
Whitelists enable you to ensure that email
from particular senders or domains are never flagged as spam, permitting
more stringent anti-spam rules. GFI MailEssentials includes a
patent-pending automatic whitelist management tool, which automatically
adds outgoing mail recipients to your whitelist. This greatly reduces
false positives, without any need for additional administration.
Whitelists can also be built based on domain names, email addresses and
Instant view of emails from new senders
The New Senders feature provides users with
an instant view of emails sent from people they never had previous
contact with, thereby helping users to better organize emails in their
email client. If an email is not found to be spam by the GFI
MailEssentials anti-spam modules and is also not on the whitelist, then
the New Senders module has the ability to move the email to a user's
subfolder, for example, Inbox\NewSenders.
Eliminates directory harvesting
Spammers often try to guess recipient
addresses by generating multiple random email addresses at a domain;
they then send their spam mail to all those addresses. GFI
MailEssentials checks the validity of ALL the email addresses included
in the mail sent, either via a query to Active Directory or through
support for LDAP, and if they are not all valid, marks the mail as spam.
Reports on spam filtering and email usage
The database-driven reporting engine allows
you to create advanced reports on your inbound and outbound email. You
can report on the amount of spam filtered and on rules which caught most
spam. You can also generate reports on user, domain and mail server
Support for SPF – the Sender Policy Framework
As most of today’s spammers spoof email
addresses, it is important to be able to check whether an email is
genuine or if it has been sent from a forged sending address. This can
be done via the Sender Policy Framework (SPF), which allows users to
test whether a particular email originates from its claimed source. GFI
MailEssentials is one of the first commercial anti-spam solutions to
support this framework. Its SPF module automatically checks whether the
mail from a particular company was actually sent by its registered mail
Set priorities for each anti-spam module
You can configure which method of capturing
spam is to be given priority, and create your own hierarchical list. For
example, the administrator can select that the whitelisting anti-spam
feature must be applied first to all incoming mail, then Bayesian
scanning, and so on.
Company-wide disclaimer/footer/header text
GFI MailEssentials enables you to add
disclaimers to the top or bottom of an email. Text and HTML formats are
supported. You can include fields/variables to personalize the
disclaimer. You can also create multiple disclaimers and associate them
with a user, group or domain.
The email monitoring feature enables you to
keep a central store of the email communications of a particular person
or department. By configuring the email to be copied to an email
address, all email can be stored in an Exchange or Outlook store, making
searching for email or content easy.
Email archiving to a SQL database
GFI MailEssentials can archive all inbound
and outbound mail to a Microsoft SQL Server database. You can search for
a particular email or an entire email thread via the included web
interface. Mail archiving is essential for back-up and search reasons.

MailArchiver for Exchange.
Seamless integration with Exchange Server, Lotus Domino and other
GFI MailEssentials integrates seamlessly with
Microsoft Exchange 2000/2003/2007: It installs on the Exchange SMTP
service and does not require gateway configuration. Via the SMTP
protocol, it also works with Exchange 5.5, Lotus Domino and other
popular SMTP/POP3 servers.
