Heluna Features

The Heluna service offers a collection of features to keep unwanted e-mail from reaching your domain. Each e-mail sent to you goes through the Heluna system, running through a sequence of filters. These filters eliminate or quarantine unsolicited spam messages, remove messages with viruses embedded in them, and also get rid of forged "phishing" attempts at stealing your identity.

Strong, Up-to-date Spam Filtering

Heluna consistently achieves better than 99% effectiveness at blocking unwanted spam through our myriad of antispam measures. Clients report that upon turning on the Heluna service for their domain, the amount of spam that they receive drops to near zero. The Heluna spam filters are constantly learning about new spam messages, and about new ways that spammers are attempting to get to your inbox.

Messages get classified as one of three types: "clean", "probably spam", and "definitely spam". E-mail that are marked as clean get delivered directly to you within moments. Messages that are designated as probably being spam get tagged with a warning notice, and then passed along. E-mail that is definitely spam either gets immediately dropped, or is placed into a temporary quarantine for you to review later, based upon your preference. With this type of message grading, Heluna offers zero "false positives", messages that incorrectly get marked as spam.

Secure Virus Protection

One of the biggest headaches for home users and businesses alike, e-mail viruses cause untolds amount of damage, both in data loss, and the amount of time required to clean up after a virus gets into your network. Modern e-mail viruses don't even need to be clicked upon to be activated, infecting your machine just by viewing the e-mail.

Heluna does away with this type of threat by immediately rejecting any e-mail message sent to your network that has a virus inside it. The antivirus filters are also constantly being updated, so that before you're even aware of a new type of e-mail virus, you can be assured that Heluna already protects you from it.

The Heluna Virus Protection page explains more about how the Heluna virus filters protect you.

Protecting Your Identity

One of the newer threats in e-mail, "phishing" attacks try to impersonate reputable businesses, such as your bank, or online retailers, in an attempt to get your personal information. With very convincing-looking e-mail messages, criminals are able to defraud people out of information such as their credit card numbers, their bank account information, or other personal demographic data.

These fraudulent messages are extremely difficult for people to recognize, but they all have one very simple flaw: they aren't being sent by the companies they are trying to impersonate. As a result of this flaw, the Heluna anti-phishing filters are able to easily pick out attempts at identity theft. These messages get treated the same way as viruses: they are immediately rejected.

Easy Setup and Maintenance

Heluna requires no software or hardware purchase, and is compatible with every e-mail server. Based upon the way that e-mail works on the Internet, Heluna acts as an intermediary host between e-mail senders and your own e-mail server. Turning on the Heluna service for your domain requires only one slight modification to your domain's mail exchanger entry (your DNS MX host) and your setup is complete.

The Heluna service is designed to be transparent, as "hands-off" as possible. Accounts within Heluna do not need any ongoing maintenance whatsoever in order to be completely functional and up-to-date. Configuration based upon preference can still be done at the user level, or at a domain-wide level, for such items as setting the sensitivity of the filters, adding e-mail addresses to approved or blocked senders lists, or turning a spam quarantine on or off.
