MailCue is a complete, self-contained email testing server packaged in a single Docker container. It provides full SMTP, IMAP, and POP3 servers, DKIM, DMARC, and SPF authentication verification, SpamAssassin spam filtering, a REST API with Python and Node.js SDKs, an interactive web UI, and a Model Context Protocol (MCP) server for AI agents. MailCue allows engineering teams to verify transactional email workflows, header signing, and spam scores locally without sending messages to real inboxes.
