It accepts all SMTP mail, keeps it in memory while it runs, and shows it in a web interface that also displays attachments, headers and the raw message. The README describes it as inspired by MailHog and MailCatcher.\n\nIt runs from a Docker image, a single binary build, or a Helm chart on Kubernetes.\n\n## Worth knowing\n\nThe README describes MailCrab as a development tool, not a service for live mail. Messages stay in memory until a restart unless a retention period clears older ones."}
