Spam Mail Filtering

We implement and monitor an effective mail filtering system to virtually eliminate junk mail, phishing, spam, malware, ransomware and viruses before they reach your mail server, resulting in saved time and advanced threat protection network-wide.

The Problem

Even though the amount of junk emails is decreasing worldwide, still at least 60% of emails received by a typical worker are junk or spam. Apart from being an annoyance and a waste of resources (particularly wasted time), there is also the opposite trend where more and more of this junk mail comes loaded with dangerous attachments, representing an increasingly higher risk for your network to get compromised.

The following pie graph represents a typical distribution of incoming mail, with the green slice representing legitimate emails:


How Does a Spam Filter Work?

A spam filter is a service or device that sits between the Internet and your mail server and filters incoming emails into different categories. The filter analizes each sender against several parameters, including IP reputation, Known Spam Source lists (RBL), Dynamically Assigned IPs (DUL), Transport Layer Security (TLS), Sender Policy Framework (SPF), approved/blocked sender lists and several other policies which are highly configurable. Too strong a filter can result in false-positives (e.g. legit emails flagged as spam), so adjusting these settngs correctly is crucial.

Here is what our console looks like for a typical client’s junk mail filtering in the course of one day (colour green represents legitimate incoming mail):
