What MailChannels Inbound Filtering is

MailChannels Inbound Filtering is a cloud gateway for hosting providers that run email at scale. It filters inbound messages before they reach hosted inboxes, using multiple independent detection engines to identify spam, phishing, and malware. Providers can route domains across their fleet through one MX record and retain controls for each domain. Customers can manage safelists, blocklists, and false-positive recovery. Intelligent Quarantine gives senders a self-service release link for messages flagged by mistake, and a daily digest lets recipients release legitimate held mail with one click. Log Search lets support agents and customers search mail history. The product page says SSL/TLS, SPF, DKIM, and DMARC are enforced inline, and mail that fails authentication does not reach customers. It 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 from engineers, 24/7.
