Managed email services can help a business run self-hosted email solutions with the same level of reliability as cloud services without compromising privacy and security.
Many small businesses have accounts with ISPs that impose limitations on how they can use their bandwidth for outgoing services. Generally, the motivation for these limitations is a good faith attempt to prevent misuse of services – blocking port 25 to prevent spam email messages being sent over the ISP’s network, for example.
However, in many cases, small businesses have legitimate reasons for wanting to run their own email services. Having control over email and how its stored can be more reliable and secure than depending on third-party cloud-based email providers, particularly when high availability is required or sensitive information is communicated through email. A business taking responsibility for its own email service is often the best way to ensure that sensitive information stays where it’s supposed to and is reliably backed up.

A US laboratory recently revealed that it has been running a network encrypted with quantum technology for several years. Quantum cryptography has the potential to provide perfect encryption.
Traditional cryptography relies on the inherent difficulty of carrying out certain mathematical calculations in a practical amount of time. For example, encryption algorithms like RSA are based on the difficulty of factoring primes. If we take two very large prime numbers and multiply them, there is no quick mathematical way of getting back to the original prime numbers from their product. It can be done, but it typically takes hundreds or thousands of years to do so.
The Domain Name Service is a crucial aspect of maintaining a stable and reliable web presence. No matter how solid a business’s web hosting might be, how well-designed their site, and how effective their search engine optimization, without a properly managed domain name service, the connection between revenue generating users and a business’s site cannot be relied upon.
In the Unix developer world, there is a prevailing philosophy that a tool should do one thing and do it well. That’s both because it’s an extremely flexible approach, allowing collections of tools to be used in combinations that could never have been thought of by the original developer and because it allows developers to cultivate a deep knowledge of the problems of a particular domain and the best ways to solve them.
It’s a powerful way of thinking about developing software, and it’s equally applicable to other areas where a combination of functional units can be organized to contribute to an overarching goal.
We know that summer is approaching and the weather is getting warmer. Luckily, while you were away from the computer, we continued to scour the internet for the best DNS, security, and enterprise IT content from the last month. So, without further ado, here’s April best.
- ICANN gTLDs: When Names Are Borrowed from an Atlas – When names are borrowed from an Atlas, things happen. Use of Geographic names have always caused some problems for two reasons; one they are in the public domain so anyone else can use them and two they connote that business is confined to just that geographic area. Like Paris Bakery, Waterloo Furniture or London Bank.
- HTG Explains: What is DNS Cache Poisoning? – DNS cache poisoning, also known as DNS spoofing, is a type of attack that exploits vulnerabilities in the domain name system (DNS) to divert Internet traffic away from legitimate servers and towards fake ones. Continue reading

When businesses are planning their infrastructure deployment strategy, there are a couple of high level ways they can think about preparing for future expansion.
Vertical scaling is the addition of extra resources to the servers in a network. For example, perhaps a business runs up against storage capacity limits, so they choose to add extra or larger hard drives to their existing servers.
Vertical scaling is the old fashioned approach, and it tends to be significantly more expensive than the horizontal scaling we’re going to look at below. If a company expects to be vertically scaling their existing hardware, then that hardware has to be built with the possibility in mind. It has to have excess capacity, extra drive bays, and so on, that will end up sitting idle until the moment of expansion comes. Such hardware tends to be significantly more expensive than commodity hardware: hardware prices don’t scale linearly.
