According to Nucleus Research, 90% of all emails received are considered to be spam. The volume of fraudulent, inappropriate and offensive emails being sent every day is growing and spammers are using every trick in the book to elude anti spam filters and use email to defraud users of money and personal information. Not only is deleting spam time-consuming but it is a security threat for your network and it can seriously affect server performance.
An effective way to beat spammers at their game is to use anti spam software like GFI MailEssentials for Exchange/SMTP/Lotus Notes. With over 60 awards to its name, 80,000 satisfied customers and the lowest prices on the market, GFI MailEssentials is an anti spam filter that captures over 98% of spam and, since it is server-based, it eliminates the need to install and update anti spam software on each desktop.
GFI MailEssentials uses a variety of technologies to beat the latest spam threats such as Bayesian filtering, white-listing technology and DNS blacklists. GFI not only excels at eliminating spam but this is done at market-leading low rate of false positives - ensuring that good and important emails are not deleted.
GFI MailEssentials can detect and block phishing emails as well as add email management tools to your mail server: disclaimers, mail monitoring, Internet mail reporting, list server, server-based auto replies and POP3 downloading.
An additional anti-spam engine
The latest version of GFI MailEssentials includes an anti-spam engine, SpamRazer, which provides a second layer of protection. It has been designed for ease-of-use and, due to frequent updates, and SpamRazer needs no tweaking to be fully effective in 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 also they will gain protection from each attack without the need to tweak GFI MailEssentials.
Precise real-time dashboard
GFI MailEssentials also ships with a precise, real-time dashboard that gives administrators a graphic view of the software's status 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; blocked spam; and also POP2Exchange logging.
GFI MailEssentials hooks into Exchange server at the SMTP protocol level. Then GFI can determine if an email is genuine or spam before exchange server downloads the entire email.
Built-in spam reporting
Administrators can now send a daily report to the users that shows how many emails he or she received and how many emails, identified as spam, were filtered. A snapshot of email traffic will show the end-user how much spam email was successfully captured. The report gives a full list of those emails identified and filtered.
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.
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 administrative hassle of desktop-based anti-spam and anti-phishing products. A server-side solution will prevent your server message stores from filling up with spam and eliminate the need to train your users on the creation and update of anti-spam rules.
Downloads updates to spam profile database
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 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 in the end-users' inboxes. This allows users to easily review mail that has been flagged as spam.
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.
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.
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 usage.
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 offers one of the first commercial anti-spam solutions to support this framework.
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 for GFI's whitelisting anti-spam feature to be applied first to all incoming mail, then Bayesian scanning, and so on.
Company-wide disclaimer, header and footer 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 and variables to personalize the disclaimer. You can even 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 for a particular person or department. By configuring email to be copied to an email address, all email can be stored in an Exchange or Outlook store, making searching much easier.
