Blocks spam using proven methods
By using all the best methods to block spam, the Barracuda Spam
& Virus Firewall provides a comprehensive spam blocker 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 Networks
and other anti-spam groups. This list is automatically updated
on each Barracuda Spam & Virus 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 & Virus 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 & Virus 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, IPs, 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 & Virus 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 youd 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 & Virus 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 & Virus 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 & Virus Firewall. Your Barracuda Spam & Virus 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
& Virus 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. Its quick, easy, hassle-free administration.
No per user charges
Barracuda Spam & Virus Firewall pricing is simple. There are three Barracuda
Spam & Virus Firewall models. Each one is designed to handle different active
user and email loads. There are no per user charges. Each model
comes with both spam-blocking and virus-checking capabilities.

servers and for multiple domains.
