"systemctl reload mimedefang" should reload the filter by way of
/etc/init.d/mimedefang, but maybe that's not setup on your system. My
version of systemd-sysv-gennerator (Ubuntu 16.04) sets:
ExecReload=/etc/init.d/mimedefang reload

Alternatively, if you use the native systemd unit files I posted a few
days ago (or the slightly updated versions attached here), reload
definitely works correctly.

> it only reloads the systemd definition of the mimedefang service

This is definitely not true. To reload the service definitions, you use
"systemctl daemon-reload".
