Carbonio
Carbonio, from Zextras, is a self-hosted email and collaboration platform: mail, calendar, contacts and file sharing in one place. It shares roots with Zimbra, which makes it a natural next step for teams moving off Zimbra.
We set up Carbonio on its own server and keep it running.
Good for
- Teams that want more than email
- Zimbra users planning a move
- Organizations that want collaboration on their own server
Zimbra
Zimbra is a long-established email and collaboration suite with mail, calendar and contacts, used by businesses and organizations worldwide.
We host Zimbra on its own server and keep it running. Thinking about what comes next? We also move Zimbra systems to Carbonio.
Good for
- Teams already using Zimbra who want it hosted and looked after
- Organizations that rely on Zimbra's calendar and contacts
mailcow
mailcow is an open-source mail server suite that runs in Docker. It brings together well-known open-source mail components with a web admin panel and webmail.
We set up mailcow on its own server, keep it updated and watch it 24/7.
Good for
- Technical teams that want an open-source stack
- Companies that want a full-featured mail server without license fees
Mailu
Mailu is a simple, open-source mail server that runs in Docker. It covers the essentials (sending, receiving, webmail and an admin panel) and keeps the rest light.
We set up Mailu on its own server and keep it running.
Good for
- Small teams that want email and nothing more
- Projects that value a lightweight, easy-to-follow setup
