I think there's a terminology mis-match here. To me "milter" is a

Nope, you've got the terminology straight.
MIMEDefang is another (much more flexible) milter - which can call a
great many other things to do its processing including SpamAssassin.
IIRC amavis can be deployed as a milter. ClamAV ships one very
similar to spamass-milter, in that it's dedicated to passing messages
to ClamAV. There are several dedicated to SPF and DKIM.

Thanks for the full explanation - the world of milters has obviously
passed me by. Another thing to research. It never occurred to me that
anyone would be using anything other than spamass-milter, which is why I
didn't understand why everyone asked what I was using.
I found the part of spamass-milter that's faking up the header easily
enough. The comment at the start of the block suggests its putting more
in the header than the code actually does - including authorisation stuff.
One kind and knowledgeable person emailed me an interesting bit I didn't
know about the sendmail.mc, and this might provide the solution (will
post when I know it works) - undocumented AFAIK, like most of this stuff!
Regards, Frank.
