Heluna standard and Heluna plus customers will see more than 99 percent of their spam messages blocked, with a near-zero false positive rate. As the Heluna system builds up a profile of your incoming e-mail over time, that effectiveness will only increase.
On average, it takes a message five seconds to make its way through the Heluna system and get delivered to your e-mail server. We also take extra care to keep your e-mail secure, and once a message is delivered to you it's removed from our servers.
Managing your e-mail shouldn't require going to a website every day. The Heluna system was designed from day one to not require any special configuration or maintenance in order to keep your e-mail free from spam. We like to think that if you're going to our website to change something, we haven't done a good enough job.
By filtering spam out of your domain's and users' inboxes, we're helping to remove the profitability of spam. Once spamming is no longer a profitable enterprise, you'll see spam levels drop precipitously. We'd love to see that happen — spam is one of the biggest blights upon the Internet.
The Heluna system learns from every e-mail that it sees. This means that when you sign up for service, you aren't getting a blank slate, you're getting an already-tuned engine for your domain. Each message that gets blocked or delivered gets analyzed and learned for even better service.
The battle against spam is always moving, due to the constant shifting and morphing of new attack vectors, new patterns, and new methods of filtering. We like to think that our clients have far better things to do with their time than tweaking filters, analyzing traffic, and the like. Leave that up to us.
Installation of Heluna is as easy as changing a DNS record for your domain. After you switch your DNS MX records to point to the Heluna system, you'll immediately notice a drop in the amount of spam that hits your inbox. After a few days, due to the nature of how DNS is cached across the Internet, you'll start to see the full benefit of the Heluna system.
Spending a little more time on your e-mail server configuration yields even better results. We work with our clients to make sure you're following our recommended setup, so that spammers don't get any opportunity to clog up your inboxes at all.
E-mail is the single most important tool for today's companies. Our customers trust us to not only filter the 78% of all e-mail messages which are spam, but to also deliver their clean messages in a timely fashion.
We've been in business blocking spam messages since 2004, and the Heluna system learns from every message that it sees. Your domain gets the benefit of years of experience and automated learning.
Changing your MX records has a small amount of risk associated with it. If you typo on a record, or point a record at a server that is misconfigured, you stand a chance of losing e-mail messages. Use the same amount of care that you would changing, for example, the DNS A record for www.yourdomain.com.
Take your current MX records (which you can find with the form above). Let's take the example of:
MX 1 mail.yourdomain.com. MX 2 mail2.yourdomain.com.
(If you only have one MX record, that's okay too.)
We're going to change those two records into four records. (If you only have one MX record, this will wind up being three records.) Change the priorities and hostnames to the following:
MX 10 reject1.heluna.com. MX 20 mail.yourdomain.com. MX 30 mail2.yourdomain.com. MX 40 reject2.heluna.com.
DNS changes always take a while to show up, but you should start seeing a smaller amount of spam hitting your network. This certainly won't stop all spam, but it's one of the methods that we use at Heluna to slow down the influx of new spam messages for our clients. We provide this as an unsupported free service for the public to use.
There's one important goal for spammers: send out as many pieces of junk mail as quickly as they can, before their base of operations is found and shut down. Once that happens, they change tactics, and the cycle continues.
With that in mind, any hurdles (no matter how small) that get in a spammer's way wind up being really effective, as they prevent a spammer from sending out as many pieces of junk as they can. What this trick does is to put up a hurdle in front of your domain.

connections. They don't ever accept any e-mail, and any attempts to deliver a message to them get immediately
rejected. They act as e-mail servers that are effectively offline.
Normally, a regular e-mail server will attempt to go to the highest priority MX host (in our case
MX 10 reject1.heluna.com) and will try to deliver e-mail. When that connection gets rejected,
a regular e-mail server will then try the next highest priority MX host (
MX 20 mail.yourdomain.com)
and so on, until they're able to send an e-mail successfully.
Spammers, however, don't generally follow the rules of how to deliver e-mail. When a spammer encounters the
connection reject by
reject1.heluna.com, more often than not they'll just give up trying to
deliver that spam message, and will move onto their next victim — hence the reduction in spam heading to your
Lastly, why have the
reject2.heluna.com record? Spammers oftentimes cheat, because "backup" or
secondary MX records often times have weaker spam protection, so a spammer will attempt to connect to the
lowest priority MX record first. They again hit the e-mail server that rejects the connection, and stop trying
to deliver that spam message.
