The only requirement is that you must have your own domain ( example: ). Our service will not work with accounts from AOL, Hotmail, Yahoo mail, Gmail, etc. If your email ends in,, or our service will not work for you. Any other setup is fine.

Our Spam Blocker and Filtering service is platform independent, so it works with all types of mail servers, including Microsoft Exchange, Postfix, qmail, Kerio, Exim, Zimbra, SendMail, GroupWise, etc. 

Our service will also work if you host your domain and email with a service provider like GoDaddy, HostGator, NetworkSolutions, etc.

And, it doesnt matter what client you use to access mail (Outlook, Apple Mail, or anything else).  We play well with everyone.


No Software or Hardware to Buy     (+/-)

Basically, we are just another hop in your email delivery.  You point your mail delivery to us (we can help you with that), we filter your mail and then deliver the messages to your Inbox.

No Required Downloads     (+/-)

You don't need to download anything.  Everything works off-site.  There is a download for users for the Microsoft Outlook mail client which adds some nice features, but this is completely optional.

No Servcie Contracts     (+/-)

We are a pay-as-you-go service.  We will not lock you into any long-term contracts.

Cancel Anytime     (+/-)

You can cancel at any time for any reason.  You will be refunded any unused portion of your service fees.

No Heavy Administration     (+/-)

Trun it on and forget about it.  Once you are up and running there is nothing to do but enjoy your spam-free mailbox.  You dont even need to add or delete user acccounts.  Our system does this automatically. 

There is an administrator login that lets you modify domain-wide settings, view your message logs, reset passwords, etc.  But as for day-to day adminsitration, there's really nothing to do.

Works on all platforms     (+/-)

Windows, Apple, Linux - it doesent matter.  Since we are a hosted service we work on all platforms and with all mail clients.

Spam Protection     (+/-)

You can now get enterprise-lever filtering for a low monthly fee.  This is the same spam filtering used at many of the world's top companies.  It's highly effective and simple to use.

Our spam databases are always current, and unlike other filters we can determine whether links embedded in email lead to known spam or malware sites.  We also protect against attempts to embed text inside images with the intent of hiding content from traditional spam filters.

Virus Protection     (+/-)

Our virus definations are updated constantly in order to catch to most recent and dangerous threats.

Malware Blocking     (+/-)

Prevent browser hijacks, adware, and other email-borne threats from reaching your mail server.

Attachment Filtering     (+/-)

We scan all attachments and decompress acrchives in search of spam, viruses and malware.

Denial of Service (DoS) Attack Protection     (+/-)

As a cloud-based service, we are positioned to stop spammers from preforming DoS attacks by rate-limitting attempts to overload your email server.

Emergency Email Spooling     (+/-)

If your mail server goes down or if you lose connectivity, we'll hold all of your incomming mail and deliver it when you're back up.  By default we can hold mail for up to five days, but this can be extended if required.


How It Works

Setup is Simple

All that is required is a simple change to your domain’s MX record. You point your mail delivery to us, we filter the mail and then deliver it to your mail server. Essentially, we’re just another hop in your mail delivery - a hop that eliminates spam. We can assist you in changing your MX records if needed.

What to Expect

Once we start detecting spam, our systems will automatically create accounts for your users and email them welcome letters. User can check in real time what messages are being tagged as possible spam. Users can also release any message, whitelist, blacklist, set filtering preferences, etc. Once a day each user will be sent a Quarantine Report. This is an email that lists any messages that were held as suspected spam during the past 24 hours. Users can release or whitelist directly from this email.

Our Service

We run high-end servers from Barracuda Networks on our backend. The Barracuda Spam Firewall is the most widely deployed spam appliance in the market today, and is used by many Fortune 500 companies. With our service you’ll be getting the same level of spam filtering as IBM, Coca-Cola, and the US Department of Homeland Security (see list), but at a fraction of the cost.

  • bubble I started out using Online Spam Solutions for their extremely competitive pricing for Hosted Exchange accounts. I then realized what a bonus their Spam Solution was. Finally, their archiving system protects me from my less than perfect backup practices. In those rare instances where I have had an issue or question, they have responded and resolved in quick order. As a small business owner, having Online Spam Solutions as a partner is a no brainer.

  • bubble Whenever I have a question I can always get someone on the phone.  With our other vendors I'm usually on hold with an overseas call center.  Please never use one of those. If you can, keep your customer service in-house - it's great.  The spam blocker works great too.

  • bubble Does what it says on the box! We were getting hundreds of spam messages a day, and this service stopped it cold.
    And talk about great support! Even with the free trial, I had personal support via email, and they even called me to help fix a setup problem.
    Highly recommended!
