all your spam-blocking so it does not bog down your email servers. In fact, with

Your email servers will process and store less incoming email. The performance
of your email servers will increase.
Blocks spam using proven methods
By using all the best methods to block spam, the Barracuda Spam Firewall provides
comprehensive spam-blocking for your company. Below are the primary algorithms
we employ to block spam. We generally recommend targeting approximately 97% blockage.
However, we provide a number of parameters that can be adjusted if necessary.
- Blacklisting
of websites & domains :
Barracuda Central maintains an up to date list of
the largest and most aggressive known spammers. This
list is maintained by both Barracuda and other anti-spam
groups. This list is automatically updated on each
Barracuda Spam Firewall.
- Keyword scanning of emails : This can be
configured on a per user basis. Our scanning methods
include a scoring system such that emails are scored
based on a number of criteria. If the score is above
a threshold, then that email is flagged as spam.
The Barracuda Spam Firewall comes with default criteria
and thresholds but you may change these.
- Checksum technology : Barracuda Central monitors
email traffic through the Internet and uses checksum
technology to keep track of the number of times a
particular message has appeared on the Internet.
If a message has appeared over a certain number of
times, it is categorized as known spam. Checksums
of known spam messages are utilized by the Barracuda
Spam Firewall to block spam messages.
- Message
authenticity checking : Several algorithms are
utilized to verify the authenticity of a message.
Some of these are simple checks to verify that the "from
address" is authentic. Some are more complex relating
to SMTP protocol.
- Blacklists and Whitelists : Domains, IP's,
and email addresses can be blocked or whitelisted
(allowed through). These lists may be maintained
on a per user basis or on a corporate basis.
- Rate controls : Utilized to stop denial of
service attacks as well as dictionary based spam
attacks. These are integrated and automatic in the
Barracuda Spam Firewall.
- File type attachment blocking : You can block
certain types of files, such as vbl scripts, from
entering your company.
User-based and corporate-based filtering
The decision on what types of emails to block can be made either at the end-user
or at various corporate levels. You have the flexibility to decide where you'd
like the decision to be made.
Suspect emails get quarantined
There are three main types of emails: emails that you want, emails that you do
not want (spam), and emails that are suspect. The Barracuda Spam Firewall can
tag suspect emails for delivery into a separate folder. You can then either have
the end user or another designated person be the final judge of what to do with
these suspect emails. If after 30 days no action is taken, the message is deleted.
Optional bulk mailboxes for users
Barracuda Spam Firewall provides optional bulk inboxes so that users can direct
spam messages straight into these areas. This prevents spam from cluttering up
their main mail system. These bulk email boxes can be checked periodically or
ignored.
Automatic system updates
A team of engineers work out of our special operations center, Barracuda Central,
to monitor the Internet for trends in spam and virus attacks. As they detect
trends, updates are created for the Barracuda Spam Firewall. Your Barracuda Spam
Firewall can then automatically update itself without any intervention. There
is no need to retrieve anything. No need to tune anything. Maintaining your Barracuda
Spam Firewall to deliver maximum protection is that easy.
Logs and reports on email statistics
System administrators can view logs or generate reports at any time from the
desktop. It's quick, easy, hassle-free administration.
