MailQ Service
Overview
MailQ is a fully configurable, API-driven email integration service designed to interface seamlessly with external SMTP relay providers. It implements a robust mail queuing and dispatch mechanism to manage, persist, and process outgoing emails generated by applications and enterprise systems. The service exposes secure API endpoints that allow applications to submit emails for immediate delivery or asynchronous queuing, with support for attachments, message prioritization, and metadata tracking. MailQ decouples email delivery from application execution, ensuring that message processing continues reliably even during SMTP outages or network disruptions.
MailQ is compatible with any SMTP relay service through configurable credentials and connection parameters. It operates on a configurable network port and utilizes a PostgreSQL database to persist email queues, delivery status, retry attempts, and comprehensive audit logs for traceability and compliance.
