SOGo provides webmail, calendar (CalDAV), contacts (CardDAV), and Microsoft ActiveSync — all bound to the Mailcow user database.
Reach it at: https://mail.example.com/SOGo/
What SOGo gives you:
- Roundcube-style webmail with conversation view
- Personal and shared calendars
- Personal and shared address books
- ActiveSync (EAS) endpoint for iOS Mail and outdated Outlook
ActiveSync limits: SOGo's EAS implementation is solid for iOS but not recommended for Outlook 2019+. For Outlook, use IMAP + CalDAV (via Outlook CalDav Synchronizer) or move that user to native IMAP.
Disable SOGo entirely by editing mailcow.conf:
SKIP_SOGO=y
Then docker compose down && docker compose up -d. Frees ~500 MB RAM if you only need IMAP.
