Self-Hosted Calendar and Addressbook services on OpenBSD
Once you have self-hosted email up and running, you may want to add the Calendar and Addressbook features to your service bag. Nowadays, the standard protocols regarding those subjects are CalDAV and CardDAV. I decided to go with Baikal , the dedicated CalDAV+CardDAV server based on the sabre/dav framework ; the same framework used in Nextcloud DAV services AFAIK. It relies on PHP and is available as a package on OpenBSD.
