Our Email and Collaboration platform is a powerful, open-source suite of productivity tools designed to help teams collaborate securely without relying on “Big Tech” platforms, integrating essential tools into a single, self-hosted interface.

 

Main Features

Mail server fluent in every protocol

Our Server speaks every standard mail protocol your users’ clients already use, so no one in your fleet gets left behind. JMAP for new apps, IMAP for everything else. Storage, search, external directory and automated DNS are part of the same server, so what you install is one mail server, not a stack of services to glue together.

Collaboration, included with your mail

Calendars, contacts and shared files live in the same Stalwart server as your mail, with the same accounts, the same disk quotas, the same sharing model and the same backups. Every standard collaboration protocol is supported, so any client your team already runs keeps working without an add-on.

Work from Anywhere

Easy access, anywhere. An efficient, modern and easy-to-use web interface for small or large teams. Less distractions and deep integration in other Nextcloud products means more productivity, wherever you are!

Use your email client of choice

Native integration into iOS, Android, macOS, Windows, Linux, Outlook, enClient and Thunderbird. Simple deployment, configuration and integration lower costs and decrease risk while leveraging your existing IT investments.

Stop spam before it reaches the mailbox

The spam and phishing filter is part of the server, not an extra daemon to install and tune. It runs at SMTP time, so unwanted mail is stopped before it reaches a mailbox; it learns from user feedback; and it combines a statistical classifier, public blocklists, phishing heuristics, sender reputation and AI analysis into a single score.
