SOGo (formerly named as Scalable OpenGroupware.org) is an open source collaborative software (groupware) server with a focus on simplicity and scalability.
SOGo provides a rich AJAX-based Web interface and supports multiple native clients through the use of standard protocols such as CalDAV, CardDAV and GroupDAV, as well as Microsoft ActiveSync.
SOGo is the missing component of your infrastructure; it sits in the middle of your servers to offer your users a uniform and complete interface to access their information. It has been deployed in production environments where thousands of users are involved.
SOGo particularly focuses on:
- Very fast and uses few resources.
- Calendaring.
- Address book management.
- Full-featured Webmail client along with resource sharing and permission handling. It also makes use of documented standards (IMAP, CalDAV, CardDAV, etc.) and thereby provides native connectivity (without plugins).
- CalDAV: The Calendaring Extensions to WebDAV protocol is vastly popular among clients (Apple iCal, Mozilla Lightning, etc.) and allows them to exchange calendar components with servers that support it.
- CardDAV: In its fourth revision, vCard Extensions to WebDAV is to address books / contacts what CalDAV is to calendaring. Less popular than CalDAV, it’s nevertheless quickly gaining momentum and is used by the SOGo Connector extension.
- Mail protocols: For messaging, SOGo fully makes use of standard protocols such as IMAP and SMTP.
- Coherent environment with Mozilla Thunderbird and Lightning.
- Microsoft Exchange ActiveSync: The de facto standard for synchronization of email, contacts, events, and tasks with mobile devices that use Apple iOS, Android, Windows Phone or BlackBerry 10.
- Events, tasks, contacts or email can be accessed through the DAV protocol. This provides excellent scripting capabilities.
- ActiveSync-compatible mobile device to easily synchronize mail, contacts, events, and tasks.
- Single sign-on (SSO) capabilities using CAS, WebAuth or Kerberos.
- Available as packages for multiple operating systems such as Debian, Ubuntu, Red Hat Enterprise Linux and CentOS.
- Internationalization support – available in over a dozen languages.
