Why MXGate?

End-to-end control over enterprise email security

Multi-Layered Protection

Four independent security layers against spam, phishing, malware and viruses. No threat reaches your network.

IP Reputation Management

With a clean IP pool and automatic rotation, your emails always reach the inbox and never land on a blacklist.

Centralized Management

Monitor all inbound and outbound traffic from a single panel. Integrate with cPanel, Plesk and DirectAdmin in 5 minutes.

How It Works

Every email passes through three stages

01

Receive & Queue

Inbound and outbound emails reach the MXGate gateway and are placed in a secure queue.

02

Analyze & Filter

Four security layers scan for spam, viruses, phishing and content within milliseconds.

03

Clean Delivery

Only clean emails are delivered to the inbox through a clean IP pool.

Understand the Problem

Don't let one user's mistake put your entire IP reputation at risk

In shared hosting environments, a single outbound mail abuse can trigger throttling from major providers like Microsoft and filtering issues on Google.

By the time traditional monitoring systems detect the problem, the damage to your IP reputation has already been done.

Eliminate This Risk
Common Problems
Sudden Outbound Throttling
ISPs suddenly restrict mail sending
Rising Spam Complaints
FBL (Feedback Loop) alerts increase
RBL Blacklists
IP addresses land on lists like Spamhaus and Barracuda
Surge in Support Tickets
Abuse complaints overwhelm the support team
One Tenant Affects Hundreds of Customers
Every customer on the shared IP is harmed

Our Solution

Automatically Detect and Isolate Problematic Senders

When a user starts sending spam, stop the problem before your other customers are affected. MXGate protects your IP reputation with multi-layered control.

Per-Tenant Mail Limits
Set a separate limit for each customer. When one tenant exceeds its limit, the others stay unaffected.
Anomaly Behavior Alerts
If an account suddenly sends 10x more mail, get an instant alert and throttle it automatically.
Sending via Clean IPs
With round-robin IP rotation, sending continues even if one IP lands on a blacklist.
Blacklist Protection
Continuously monitors RBL lists like Spamhaus and Barracuda, warning you before a problem occurs.
One-Click User Isolation
Isolate a problematic user instantly. Your other customers' mail traffic continues uninterrupted.

Customer Reviews

Turkey's leading companies trust MXGate

★★★★★

After we started using MXGate, I began receiving thank-you messages from my own customers. Instead of chasing a new spam method every day, I now sip my coffee and focus on other work. Setup and management are so simple that I can integrate new mail servers very easily too. Congratulations to the whole team for providing a service like this.

★★★★★

Before using MXGate, I received phone calls almost every day about spam emails and messages that couldn't be sent or never reached the recipient. After we started using the system, spam traffic dropped by around 99% both in our own accounts and in our customers' accounts. Whenever an email isn't sent or doesn't arrive, I can immediately see the reason on the panel and respond quickly. Thanks to its effective spam filtering and the control it offers, our email operations have become far more secure, organized and trouble-free. We are very pleased with the service you provide.

As a company providing enterprise email services, we had the chance to use and compare different email security solutions. MXGate integrated seamlessly into our Zimbra infrastructure and met our expectations in a short time. We are especially pleased with its success at filtering spam, phishing and malicious email — unnecessary inbox traffic dropped noticeably and our users' email security improved significantly. Thanks to the clean, clear management panel, day-to-day administration is very practical too. On top of that, the technical support team's fast responses and solution-oriented approach are among the product's strongest sides. We can confidently recommend it to companies seeking a reliable and effective enterprise email security solution.
