# MailMERC

> Cloud-based email security gateway for SMBs and enterprises. Filters spam, viruses, malware, and phishing before they reach your inbox. Fully managed — no dashboard, no infrastructure, no knobs to tweak.

## What Is MailMERC

MailMERC sits between the internet and your mail server using MX record redirection. Every inbound email is scanned by multiple engines:

- **Spam Filtering** — Multi-engine scoring with industry-leading classifiers and reputation databases.
- **Virus & Malware Scanning** — Multiple antivirus engines detect known malware, ransomware, and zero-day threats.
- **Phishing Protection** — Spear-phishing, BEC, and domain impersonation detection via sender reputation and content inspection.
- **DNS RBL Protection** — Multiple Realtime Blackhole Lists queried in parallel to block known spam and malware sources.
- **Content Filtering** — Team-configured DLP rules and compliance enforcement, customized per client.
- **URL Scanning** — Real-time URL analysis against threat intelligence, blocking malicious links even if they were clean at send time.

Service is fully managed by MailMERC's team. They learn each client's email patterns and optimize filtering rules specifically for that business. No self-service dashboard or administrative overhead.

## How It Works

1. Redirect your domain's MX records to MailMERC.
2. MailMERC scans every inbound message with multiple engines.
3. Clean mail is forwarded to your mail server; threats are blocked and logged.
