DBus is only part of the interface. Majority of the communication goes trough 
custom protocol that has changed substantially between KDE 4 and KF5 versions 
(basically in KDE 4 it was an IMAP-like text protocol, in KF5 the protocol is 
purely binary).

It might be possible to write a translation layer from the binary protocol 
that modern Akonadi speaks to the old protocol that kdepimlibs4 understand. 
That would be a lot of coding effort though and I'm not sure if all the 
behavior can be mapped still.

I don't want to disclose too much yet, but there might be NNTP support coming 
to KMail at some not-too-distant point in the future ;-)
