How To Stop Getting Blocked by Spam Gateway Filters
When the pandemic era hit, digital vulnerability rates went up to 54% in terms of phishing emails and related ransomware. Although these dark times started dissipating, global data breach losses kept growing, reaching a peak of$4.35 million in 2022.
With that in mind, more and more security-aware companies and corporations are looking in the direction of spam gateway filters. They are known for their strong mechanisms aimed at keeping unwanted and potentially harmful emails at bay. They act as a barrier between external senders and internal company infrastructure.
Although spam getaway filters aren’t the only spam filter warriors on the watch to refer to, these on-premise filters deserve your attention if you care about email compliance, data privacy, network connectivity limitations, customization needs, and performance requirements. You should know how they work to make sure your carefully-crafted email doesn’t violate the policies and will not get blocked.
Read on to learn the mechanism behind gateway spam filters, their benefits, limitations, and how not to be blocked by these powerful blockers, and get an overview of the most popular on-premise solutions.
What Are Spam Gateway Filters & How Do They Work?
Spam gateway filters are on-premise online security solutions developed to detect and mitigate spam emails before they hit recipients’ inboxes. The software is usually installed on a physical server (or your computer server) to check and test for malware before it can reach the intended inbox.
🤔 What is the difference between an email gateway and an email server?
A mail server is a dedicated server that manages all incoming and outgoing emails. It keeps, processes, and delivers emails to intended recipients. Meanwhile, an email gateway is a software application that works as a filter between the internet and the email server, and acts as a protective layer for the mail server, filtering out any harmful threats like spam, viruses, or phishing emails. So, while a mail server manages the storage and delivery of your incoming and outgoing emails, the email gateway serves as a protective layer that filters out spam.
Most spam filters are designed to maintain a perfect balance between blocking as many unsolicited emails as possible and bringing false positives to a near-minimum rate (minimizing false blocking), and gateway filters aren’t an exception. A system administrator can preset filtering to acceptable criteria so that no unintentional customer losses occur.

How Spam Gateway Filters Keep inboxes Secure?
✅ Quarantining or blocking emails that contain detected malware, phishing signs, spam, and other potentially malicious content (criteria are preset by a system administrator).
✅ Allowing system admins to limit bulk email deliveries.
✅ Supporting data loss prevention functions that thwart accidental or intentional leakage of sensitive information via emails.
✅ Allowing network administrators extra control and insight into traffic in and out of their network.
✅ Supporting greylisting.
