Mailcow

Mailcow is a comprehensive open-source mail server suite: email, calendar and contacts via the integrated SOGo webmail, plus effective spam protection with Rspamd and virus scanning with ClamAV – all manageable via a modern admin panel. You can set up domains, mailboxes and aliases in just a few clicks, without having to touch any configuration files. If you don’t want to leave your email to Microsoft or Google, Mailcow provides you with a fully-fledged mail server of your own. However, such a server needs to be run properly – and this is exactly where Managed Mailcow Hosting comes in: you use the mailboxes, whilst OpenHosting takes care of server operations.

Who is Mailcow suitable for?

Mailcow is ideal for SMEs that wish to manage their business email communications on their own infrastructure: trust offices and law firms handling confidential client correspondence, medical practices dealing with sensitive patient data, or agencies that manage numerous domains and mailboxes for themselves and their clients. Clubs and associations also benefit, as an unlimited number of addresses and aliases can be created without licence fees per mailbox. Thanks to calendar and contact synchronisation via SOGo, Mailcow replaces traditional groupware such as Exchange for many teams.

Mailcow hosting in Switzerland

With OpenHosting, your mail server runs in Swiss data centres in the Zurich region – your business correspondence remains in Switzerland and the service complies with the nDSG. When it comes to email in particular, the managed approach pays double dividends: OpenHosting keeps the installation up to date with the latest updates, continuously monitors operations and backs up your mailboxes daily in line with the 3-2-1 principle (hourly on the Business plan). The support team also assists with the migration of existing mailboxes, for example from a previous provider or from Microsoft 365. Managed Mailcow Hosting is available from CHF 19/month with unlimited domains, even on the Starter Plan; the Business Plan adds relay options, a central admin panel and priority support. This allows you to combine the independence of your own mail server with the convenience of a managed service – without monthly costs per user.
