REDDOXX MailDepot is an on-premise software solution for the legally compliant and audit-proof archiving of emails. Deployed as a virtual appliance, it operates independently of an organization's mail server to capture all incoming, outgoing, and internal communications through methods including journaling and SMTP forwarding. The system reduces storage load on primary mail servers using compression, deduplication, and automated offloading of data to flexible storage targets such as NAS or SAN. It is designed to be compatible with various mail server infrastructures and supports deployment in high-availability clusters and multi-domain environments.
To ensure data integrity, the system utilizes hashing and encryption for tamper-proof, revision-safe storage of communications, including structured e-invoices in formats like ZUGFeRD and XRechnung. A full-text search engine indexes email bodies, metadata, and text-based attachments to facilitate data retrieval. The compliance framework includes role-based access controls, a multiple-eye authorization principle for sensitive operations, management of retention policies, and tamper-proof audit logging. Administrative functions support user synchronization with Active Directory and the centralized management of email data, while access to the archive is provided through client, web, and mobile applications.
