Why do you need a mail filtering solution?
Email is the life-blood of many businesses today. Unfortunately, SPAM, or unsolicited commercial email (UCE), threatens to overwhelm corporate network infrastructure, network and server administrators’ already-busy schedules, mail server resources, and user inboxes. Legitimate messages are buried under inboxes overflowing with unwanted messages, or simply get lost in the shuffle due to overtaxed servers and infrastructure.

SPAM accounts for 50-90+% of all incoming email volume for most of our customers.

Why do I need a managed SVI E-Mail Service?
Most products or services that claim to filter out SPAM fall short in one (or more) of several areas, including:

They use only a very small number of techniques to detect SPAM

Worse, they use some of these techniques as a definitive classification of spam or not spam.

They use techniques that require the product or service to be “trained” by the mail users (most users will not do this!)

They operate after the message has already touched the mail server – which limits the types of analysis that can be performed, and wastes even more resources at the mail server
To greatly improve accuracy, SVI uses a comparatively large number of techniques to detect SPAM, which can be tweaked (if desired) by site mail administrators, and even by end-users. (The mail administrator(s) can permit or deny this, in fine detail.)

What are the advantages of the managed SVI E-Mail Service?
Most businesses don’t have the staff or resources available in-house to implement first-class SPAM filtering. SVI allows you to affordably leverage our experienced personnel to achieve more effective results than would probably otherwise be realized using simpler techniques and products.

Among other things, Primary Network maintains the hardware and software, constantly updates the system to meet new threats, and provides sparing. The configuration database of each SVI E-Mail Service is backed up remotely - should a hardware failure occur, a new box can be built to replace it very quickly.

SVI is very flexible – options can be set on a per-appliance, per-domain or subdomain, and even per-user level as desired.

Can SVI do anything besides filter SPAM?
Of course! SVI can, among other things:

Remove all executable attachments – this is extremely useful for defeating so-called Day 0 viruses and worms (Day 0 refers to a virus or worm that spreads before antivirus packages can be updated to detect them)

Perform detailed mail logging and reporting

For a traveling user, replace large attachments with a private URL – so the user isn’t forced to wait for extended periods of time when checking a POP mailbox

For messages from an unknown address at a competitor company, quarantine messages until either an administrator clears the message or the sender agrees to an Acceptable Use Policy, at which time the message is released

Eliminate “forged” messages (email with an internal From address, but which arrives from the outside)

How is the SVI E-Mail Service protected from hackers?
All network access to SVI is heavily filtered. In addition, administrative access by Primary Network is accomplished using strong encryption and authentication.

How is SVI customized?
There is no configuration or customization of the SVI appliance required of the end users or network administrators. The default settings work extremely well in most cases. If changes are desired, they can be made through the SVI web management interface. There is a web interface for the mail administrator(s), for domain/sub-domain administrators, and for end users. All levels can be utilized, or disabled as needed.

How does SVI remove mail determined to be SPAM?
SVI by default classifies every email message into one of three categories: Not SPAM, Probable SPAM, or SPAM. If a message qualifies as SPAM or Probable SPAM, SVI can:

Pass the message through unaltered

Add a header or subject tag to the message so the mail server and/or client can treat it (for example, file it into a “SPAM” folder for review)

Delete the message outright

What kinds of reports does SVI generate?
SVI logs everything that goes through the box except for the body of the message. Reports can be generated for individual users, particular messages or similar messages, number of messages received, number of spam messages and percentages of legitimate mail versus spam.

How is SVI backed up?
Configuration information is backed up via secure link to Primary Network.

Does SVI require a particular type of mail server?
No, SVI works as a mail gateway completely separate from the mail server.

Can I use SVI if I don’t have my own mail server?
Yes. The only requirement is that you have your own email domain or subdomain.

Can SVI act as my mail server?
No. SVI is an email gateway, not a server.

Do you offer any High Availability options?
Yes. Multiple appliances are able to operate in parallel for redundancy and/or load balancing.

At about what mail volume is a second appliance required?
Each SVI appliance can handle approximately 250,000 messages per day. When demand exceeds that, a second SVI box can be installed and operated in tandem.

How much does SVI cost?
$1.50/Per month for each E-Mail account. Sign Up Now!

Where does SVI sit in my Network?
SVI sits in front of the firewall outside your network. As such, there are no complex router or firewall configuration changes necessary.

How long does it take to install SVI?
SVI can be installed within 15 minutes. Its simplistic architecture makes installation and removal, if necessary, a brief and uncomplicated process. There is no network outage or downtime required for SVI installation.
