## Overview

### Key benefits of Stalwart

 An all-in-one mail and collaboration platform: Stalwart unifies email (SMTP/IMAP/JMAP), calendar, contacts and file storage in a single server, eliminating the need for multiple separate tools.
 Strong, modern security: it provides encryption at rest (S/MIME or OpenPGP), transport-layer security (TLS + DANE / MTA-STS), sender authentication (DMARC, DKIM, SPF, ARC), and fine-grained access control to protect both mail and stored data. 
 Seamless team collaboration: beyond email, Stalwart includes calendars (CalDAV), shared contacts (CardDAV), and file storage/sharing (WebDAV), allowing teams to coordinate, share documents and manage contacts in one integrated environment. 
 Built-in anti-spam \& anti-phishing protection: thanks to a robust filtering system (spam classifier, blacklists, greylisting, sender reputation, phishing heuristics), inboxes stay clean and safe without needing third-party filters.
 Built to scale: designed from the ground up to handle small installations or grow to millions of mailboxes, with load balancing, high availability, fault-tolerance, and modern distributed storage support.

The software provides comprehensive support for JMAP, IMAP four, POP three, SMTP and WebDAV protocols. It consolidates traditional email infrastructure components such as the mail transfer agent, message store, spam filter, calendar and contact management into a single executable with a unified configuration.\n\nThe solution features a comprehensive security framework that includes encryption at rest with S/MIME or OpenPGP, transport security through DANE, MTA-STS and TLS reporting, and automatic certificate provisioning via ACME. Granular access control lists, rate limiting and fail two ban protection prevent unauthorized access. Spam and phishing defenses rely on DMARC, DKIM, SPF and ARC for sender authentication, statistical spam classification with automatic training, DNS blocklist verification and phishing protection against homographic and spoofing attacks. Collaboration capabilities extend to calendar and event scheduling with free and busy support, contact management and file storage with secure sharing. Administrative tools include enhanced Sieve scripting, dynamic configuration rules and full-text search across seventeen languages.\n\nThe architecture accommodates integration with various storage and authentication backends, offering deployment flexibility. When paired with modern storage engines such as FoundationDB, the system scales to handle millions of mailboxes without requiring coordinators or proxies. Features such as node autodiscovery, partition-tolerant failure detection and load balancing ensure continuous operation.","image":"https://gdm-catalog-fmapi-prod.imgix.net/ProductScreenshot/ef6080dc-83a8-45d2-85fc-49090793251f.png","url":"https://www.getapp.co.uk/software/2083156/stalwart","@id":"https://www.getapp.co.uk/software/2083156/stalwart#software","@type":"SoftwareApplication","applicationCategory":"BusinessApplication","publisher":{"@id":"https://www.getapp.co.uk/#organization"},"offers":{"price":"2.4","@type":"Offer","priceCurrency":"USD"},"operatingSystem":"Cloud, Windows on premise, Linux on premise"},{"@id":"https://www.getapp.co.uk/software/2083156/stalwart#breadcrumblist","@type":"BreadcrumbList","itemListElement":[{"name":"Home","position":1,"item":"/","@type":"ListItem"},{"name":"Email Security Software","position":2,"item":"/directory/475/email-security/software","@type":"ListItem"},{"name":"Stalwart","position":3,"item":"/software/2083156/stalwart","@type":"ListItem"}]}]}
