SPAM
and AntiVirus Filtering
 Our virus definitions and SPAM filters
are constantly updated and the filtering is done
at at the main servers, which means that the
bad email will never even hit your account!
NEW! Advanced Anti-SPAM Filter
We've added an excellent optional mail filter called MailFoundry to our list of available applications. If you are getting a lot of junk mail you may want to try MailFoundry. We switched our filtering system over to MailFoundry and the difference is dramatic!
MailFoundry is optional on basic hosting accounts and adds a nominal monthly fee. Mail foundry can be enabled easily through your control panel and requires no configuration. You just click a button and it starts working!

Clam AntiVirus (free and included)
Scans
incoming
email
and
attachments
for viruses identified in the OpenAntiVirus
database. Emails identified as infected
are deleted before they reach your
inbox.
The main purpose of this software
is the integration with mail servers (attachment
scanning). The package provides a flexible
and scalable multi-threaded daemon, a command
line scanner, and a tool for automatic updating
via Internet. The programs are based on a
shared library distributed with the Clam
AntiVirus package, which you can use with
your own software. Most importantly, the
virus database is kept up to date .
SpamAssassin (free and included)
Scans
incoming
email
with
a
variety
of
heuristic
tests
to
identify
and
tag
potential
spam. Mail clients and webmail can
delete
or filter the tagged spam to any folder
you
choose.
The spam-identification tactics
used include:
header analysis: spammers use a number of
tricks to mask their identities, fool you
into thinking they've sent a valid mail,
or fool you into thinking you must have subscribed
at some stage. SpamAssassin tries to spot
these.
text analysis: again, spam mails often have
a characteristic style (to put it politely),
and some characteristic disclaimers and CYA
text. SpamAssassin can spot these, too.
blacklists: SpamAssassin supports many useful
existing blacklists, such as mail-abuse.org,
ordb.org or others.
Razor: Vipul's Razor is a collaborative
spam-tracking database, which works by taking
a signature of spam messages. Since spam
typically operates by sending an identical
message to hundreds of people, Razor short-circuits
this by allowing the first person to receive
a spam to add it to the database -- at which
point everyone else will automatically block
it.
Once identified, the mail can then be optionally
tagged as spam for later filtering using
the user's own mail user-agent application.
SpamAssassin requires very little configuration;
you do not need to continually update it
with details of your mail accounts, mailing
list memberships, etc. It accomplishes filtering
without this knowledge, as much as possible.
MailFoundry - Advanced Spam and Virus Filtering (Additional Cost)
If you are still receiving a large amount of spam and you have adjusted your anti-spam settings as much as possible, you have two choices: get rid of the email address or try our advanced mail filter, MailFoundry.
MailFoundry's email protection engine, MessageIQ, is the newest, most capable engine available on the market today.
How it Works
MessageIQ uses targeted spam profiles that were created to defeat actual spam outbreaks as they happen. It doesn't use any heuristics or learning systems in the approach. Those systems give fairly decent kill rates, but have horrid false positive rates. They also need constant maintenance and "training" by the system administrators and end users.
The MessageIQ NOC examines email threats as they happen in realtime from around the globe. Over 500,000 messages per hour are classified automatically and new profiles or updated profiles are sent out every five minutes to MailFoundry appliances world-wide. The profiles are built around current attacks based on their key fingerprints. This involves more than just analysis of the email content. This involves examination of the sending email server, network data, header data, message content and other attributes.
These spam profiles give MessageIQ the ability to quickly and accurately identify emails in realtime.
MessageIQ is a hands-off operation solution. MailFoundry updates the spam profiles every five minutes as email threat outbreaks happen so MailFoundry appliances world-wide have the most up to date profiles without any interaction with the network admins or end users. Since it doesn't have false positives, it also doesn't have individual user logins for whitelist management, etc. Many of the features common on other solutions exist as a result of their high false positive rates. You won't find any of that on the MailFoundry platform.
