Email Spam Filtering

When focusing on protecting a business against e-mail viruses, many companies use a two way tactic. The initial step consists of running an antivirus program directly on the message server. This application screens inbound and outbound e-mail and seek every mail for infections. The second element to a regular e-mail antivirus method, consists of using antivirus programs on every user computer. This software supervises the workstation’s file system and also into Microsoft Outlook. The goal is that the client-level antivirus tool could capture any infections that have managed to escape past the antivirus software working on the mail server.

This two tiered method is effective, however, by relying on workstation and server level antivirus application, you are essentially permitting e-mail viruses to get into your company, but just in some parts of your network. It is completely essential to have antivirus software on each machine in your company. At the same time however, I have usually experienced that antivirus applications must be the last type of protection, not the first. It is a lot better to keep viruses outside the network, than it is to rely upon the antivirus application to eliminate malware after they have entered your systems.

An effective solution to guard your network against e-mail viruses is to use managed email spam filtering. The concept behind hosted email spam filtering is that you outsource malware/virus/message scanning to a third party firm. The supplier cleans your inbound messages before their delivery at your email server. Remember that managed email spam filtering is meant to complement your
present antivirus procedures, not to replace it. It is actually vital that you run your regular antivirus programs that will guard your network should an infection get by the hosted email spam filtering procedure or in the event a user brings a spyware into your company by means of their personal devices if you are allowing BYOD (Bring Your Own Device).

How does email spam filtering works?

The key to knowing how hosted filtering functions is to understand a small bit on how the domain name system ( DNS ) operates. Every single domain name on the web has a DNS server which is regarded as authoritative for that domain. At the very least, this DNS server has a host record that provides the IP address of the domain’s Internet site. Normally, the DNS server has a mail exchanger ( MX ) record for a site domain, which specifies the IP address of your domain’s email server. For instance , if a person was going to send a message to [email protected], their system will execute a DNS query to locate the MX record related to the 123onit.com domain.  As soon as this record is found, the client computer system will know where to deliver the e-mail.

As we have seen, hosted email spam filtering is an effective choice for augmenting your business data safety. Even when you think that your present antivirus approach is 100% efficient, hosted filtering remains the best idea since it enables you to preserve Internet bandwidth because infected emails will no longer be delivered to your own email server. As an additional benefit, most of the organizations that provide hosted email spam filtering services also provide the option of archiving all of your email messages history, consequently enabling you to preserve a backup of your messages for days to come.

Even if only one user spend time sorting and erasing unwanted and unsolicited email messages, you are losing time and money. Let us show you how we can help by contacting us today.
