You made my day! mimedefang.pl referred to /etc/mail/mimedefang-filter 
and on the old system there was a symlink to our filter 
(/opt/mimedefang/bin/mimedefang-filter) but on the new system this 
symlink was not present. A big Thank You!

This makes me wonder: when compiling mimedefang with:

./configure --prefix=/opt/mimedefang and --exec-prefix=/opt/mimedefang 
et cetera

should mimedefang.pl not search for a default filter under 
/opt/mimedefang/bin instead of /etc/mail?
