Look at "systemctl show spamassassin.service".

That gave:

    Before=exim4.service

Exim4 was not installed, but there was a /etc/init.d/exim4. After removing that it was OK. Tab does not produce spamassassin.service anymore.

Now I have to do the same work for the other unit files that give a not-found.

Removed 11. Later in the week I will remove the rest.
