There are no per user costs, the CIX Spam and Virus filter is charged on a per hosting account
basis. You can map multiple domain names to a single hosting account, and setup potentially hundreds
of mailboxes... yet all you need is this one spam filter supplied as an annual cost of £30 ex.VAT.
In very basic terms this is how the filter processes your emails. Although the process looks
simple hundreds of checks can be carried out on each and every email that is sent to your email
addresses to determine, with an ultra high degree of accuracy, whether the email should be treated
with as dangerous, potentially spam, or legitimate. All of the checks are completed in seconds,
so there isn't any noticeable delay to your email.
Emails with Viruses
- Option to toddle on / off this check
- If Enabled viruses are deleted
- No bounce generated
Spam Borne Emails
- If the source IP address is on a block list the email is bounced to sender without exception.
- If initial block list check completes then the email is moved onto the content checks.
If the email completes the content check with a score lower than the specified sensitivity
score it is treated as legitimate and delivered.
- If the email exceeds the set sensitivity the below 'spam filtering options' dictate the next action.
- Emails which aren't from a blocked IP
- Emails which complete the content checks
- Are delivered as per the hosting accounts mail settings
With its self learning Bayesian database and point scoring engine, coupled with our proactive
monitoring of new techniques employed by Spammers - thus ensuring new Spam is filtered without
risking an increase to genuine (ham) mail. Such is the power and accuracy of the filter that the
likelihood of incorrectly identifying a message as spam is negligible and makes it nigh on
impossible for spammers and virus writers to craft their messages to bypass the filters.
Using this feature all emails which are considered as spam are moved to the mailbox you specify.
This means you can still download them, but allow your mail program to handle them differently, or
alternatively pass them all to one contact within your office who can check for any false positives.
Quarantine Spam Email
This feature prevents you downloading potentially harmful emails. The emails which are considered
as spam are moved to a folder called 'spam' which can only be accessed online using our webmail
Should any emails be incorrectly labelled as spam you can easily tell the webmail to move the
email to your inbox and thus you can download it normally.
Mark Message as Spam
Each suspected spam message can have its subject prefixed with a given word; the default being
SPAM:. Thus, allowing you to download the messages locally along with all your other email and filter
in your own mail client (eg direct them to a specific folder).
Delete Spam Email
Use our systems to ensure no spam is ever sent to you. Our systems are upwards of 99% accurate
in terms of identifying spam and as such you can have the confidence that only legitimate email
will be routed to your mailbox. This is the default action for all virus borne emails.
Individual email addresses and domain names can be added to the allow list. As long as the
source IP address isn't on a known block list the email will always be delivered to you no
matter what scores may be applied due to the content it contains.
Personal Black Lists
You can add individual email addresses or whole domain names to a block list. Any emails
sent to you by these addresses will bounce back regardless of the content contained within
them. This can help cut down unwanted or nuisance senders contacting you.
Focusing on a self evolving point scoring system, all email is scanned and checked by
thousands of different rules to check its validity. The higher the score, the more likely
it is spam. The tolerance scale allows you to either increase or decrease the points required
by our filter for a message to be considered as Spam.
When the filter identifies a message as junk, it makes a report indicating why the message
was targeted as such. This can prove interesting as to why some emails mail have been deemed
to be spam in the first place. The report is attached as text file.
DNS Block List Checks
DNS block lists are used as a means of blocking sending servers that have a reputation
for sending spam, and can considerably reduce the amount of spam received by a domain. Each
list has its own policy regarding how servers are blocked, with some stricter than others.
We have three levels to pick from allowing you to check how thorough you would like us to be.
By default we recommend the 'basic' checks which include popular block lists such as SpamCop,
Spamhaus and Barracuda.
The majority of computer viruses are spread through email, and their effects can be
devastating in terms of data breaches and lost hours. Our filter recognises that there
is no such thing as a legitimate virus, so emails which contain a known virus are stopped
and deleted without exception by default. Advanced users can choose to disable this feature,
but we strongly recommend against it. Our virus databases are updated hourly to ensure we
offer the maximum protection to our customers.
Reverse DNS Check
Most mail servers will have a fully qualified domain name associated to their server.
This feature simply checks that the sending server have a valid PTR record, and if not
the connection is dropped with an explanation (eg Sending IP address 18.104.22.168 has no
reverse DNS). It can be enabled / disabled depending if you would like this be checked
as part of the spam filtering routines.
Spam Graphical Statistics
To show you how our spam filter has benefited you we provide you with graphical
statistics. These are detailed statistics which are provided on a daily, weekly and
monthly basis. They include not just a graph shown details of the filtering, but which
checks caught the highest amount of spam borne email (eg block list checks, caught x
number of emails to your domain).
