Spec score 7.9 #3 of 19 in Cloud Email Security

What it is

MailChannels Inbound Filtering blocks spam, phishing, and malware before they reach hosted inboxes. It is designed for hosting providers that handle mail at scale, with a multi-tenant setup: one MX record can protect domains across a provider’s fleet, while controls remain available for individual domains. Multiple independent detection engines identify threats, and the product says it enforces SSL/TLS, SPF, DKIM, and DMARC inline, preventing mail that fails authentication from reaching customers. Customers can manage safelists, blocklists, and false-positive recovery. Intelligent Quarantine offers senders a self-service release link, and a daily digest lets users release legitimate held messages with one click. Log Search enables customers and support agents to find messages in mail history. The service supports downstream SMTP mail servers and has a cPanel and WHM plugin; the plugin requires cPanel and WHM version 68 or higher and PHP 5.6 or higher. Setup includes domain provisioning, mail-server preparation, and routing inbound traffic through MailChannels. Pricing is on request. The product page advertises a 30-minute human response, 24/7, from engineers.
