The path of an email message
When an email message is sent over the Internet, it is directed to one or more email servers that are designated for the recipient’s domain name. For example, an email message sent to john@widgets.com would travel across the Internet to the mail server for widgets.com – this might be a server called mail.widgets.com.
The information about which mail server(s) should receive email for a given domain is contained in that domain’s DNS (Domain Name Service) records. In our example, the widgets.com domain would have in its DNS records an entry - known as an “MX” (mail exchanger) record - that directs all inbound email destined for widgets.com to the server named mail.widgets.com.
It is a simple process to change the MX entry for a given domain, so that inbound email is redirected to systems that filter the inbound messages for spam and viruses. Those systems, hosted by a managed service, in turn deliver the filtered messages to the organization’s mail server.
Where Katharion fits in
Katharion maintains highly specialized systems that do exactly that. Inbound email is automatically filtered – in under one second – then delivered to a company’s mail server, whether that mail server is hosted at the company’s office or at a third-party location such as an Internet Service Provider.
Tens of thousands of companies use this approach because it is simple to implement, compatible with any existing mail server, and a very effective defense against spam and email-based viruses.
Get started in minutes
To activate Katharion, all that is necessary is the MX record change that enables incoming email to be seamlessly routed through Katharion’s service. Typically, this simple change can be completed within a few minutes and customers begin experiencing the benefits as soon as the change is made. There is no interruption to an organization’s email, nor are any changes necessary with the company’s mail server or email software.
