What is SOGo?

SOGo is a groupware server that provides a rich AJAX-based Web interface and offers your users a uniform and complete interface to access their information.

The SOGo Webmail extension provides the following features:

• Localization. SOGo is available in over a dozen languages so you’ll always feel at home. If your language is missing, you can easily contribute to the project and submit your translation.
• Sharing. Share your mail, calendars, and address books with other users. Define specific rights to each person or group of persons.
• Reminders. Set alarms to important events and get alerted directly from your browser.
• Recurring Events. Define precise recurrence pattern for your repeating events and create exceptions if necessary.
• Delegation. Delegate access to your mail account or delegate an invitation to another person.
• Free/Busy Time. Before sending an invitation, see the free/busy periods of attendees, either from the local SOGo server or a remote Microsoft Exchange server. Automatically set off-hours as busy if you like.
• HTML. Compose HTML mail with the complete inline rich-text editor.
• Categories. Choose from a predefined set of categories or create your own categories and associate them to your events and contacts.
• Multiple Mail Accounts. Configure all your mail accounts (IMAP) from SOGo and forget about login-in to multiple webmail services.
• Mail Return Receipt. Request or answer to return requests to confirm the arrival of messages.
• Mail Filtering. Define powerful server-side filters to automatically act on new messages. Forward, discard, reject, flag, or move incoming mail depending on complex criteria.
• Forward and Auto-Reply. Set an auto reply while on vacation or forward all your incoming mail to one ore many alternate email addresses.
• Export/Import. Export calendars or import events from a vCalendar file. Export contacts to LDIF or import cards from a LDIF of vCard file. Export a mailbox to zip archive.
• Two-Factor Authentication (2FA). Protect your account from unauthorized access using an Authenticator app.
