The Benefits of Implementing an MX Spam Filter

An MX spam filter is another name for a cloud-based email filtering service to which businesses subscribe and then connect to the service by redirecting their mail exchanger (MX) record. In most cases an MX spam filter is the most cost-effective way to protect businesses from spam emails and the threats that accompany them. However, this is not the only benefit of implementing an MX spam filter.

Because the mechanisms driving an MX spam filter are cloud-based, maintenance of the service and all necessary updates are the responsibility of the service provider. This includes implementing counter-measures to combat the growing sophistication of phishing emails, which businesses may struggle to apply sufficiently quickly on hardware devices or on-premises software installations.

This means that business using an MX spam filter are often better protected against spam emails and phishing emails than businesses using alternate solutions – provided the counter-measures implemented by the service provider are effective and easy for system administrators to understand. As with hardware and software solutions, not all cloud-based email filtering services are the same.

How to Select an MX Spam Filter Vendor

Although the history of an MX spam filter vendor is important, it is not as important as the service they are offering. Phishing counter-measures are just one consideration. Other considerations include the front-end tests their service performs on inbound mail, the flexibility and scalability of the service, and other features that should be included in the service without additional charge.

Front-end tests vary considerably. Vendors such as Microsoft use a combination of processes that can be complicated to administer. Due to the potential complications, genuine senders can have their emails returned and “false negatives” (i.e. spam emails) can avoid detection. There are also issues with the way in which Microsoft updates its anti-spam software retrospectively rather than proactively.

By comparison, vendors such as SpamTitan proactively reduce spam emails and email-borne threats through the Greylisting process. This process helps prevent spam from previously unidentified sources while accelerating the delivery of business-critical emails from trusted sources. It also helps prevent bottlenecks on the mail server to eliminate delays in the filtering service.

Flexibility and scalability are generally standard with cloud service providers – provided businesses are not locked into receiving a certain level of service. Other features that should be included without additional charge include synchronization with management tools, outbound scanning and malicious URL blocking to further protect businesses and their employees from the threat of phishing emails.
