The base URL for WebDAV managed attachments, excluding the Cyrus-specific
URL paths. Typically, this only includes the HTTP scheme and host name at
which DAV clients may fetch managed attachments from, e.g.
"https://dav.example.com".  If not specified, the target host of the DAV
HTTP request that uploaded the attachment will be used. For JMAP, the
Link.blobId property of JSCalendar objects will be disabled.
