A database server is essentially useless without data and none of them can 
access stored data other than their own.

Extending an existing database server to be able to connect to an IMAP server, 
read a local maildir, connect to a CalDav server or read a local ical file 
would essentially require forking that server's code base and maintaining it 
from there on.
