Thanks William, you’re quite right.  I dusted off my old notes for setting up 
dkimproxy and it still works just fine with OpenSMTPd 6.7.1p1 on FreeBSD 12.1.  
 The updated syntax in that link was helpful thank you.

Of course it still means running a pool of separate proxy processes just for 
DKIM signing which is a step backwards from having a dedicated filter, but it’s 
a much leaner alternative to using rspamd, and in my experience much more 
reliable too.

When I get some time I’ll have another look at trying to port Martijn’s filter 
from OpenBSD.
