[Mimedefang] action_add_header question

[Nels Lindquist]

Is it possible for a milter to prepend a header to a message?

I'm trying to implement SPF checking, and I want to add a Received-
SPF: header.  The implication from the documentation is that it 
should be treated like a Received: header and prepended to the 
existing headers, but action_add_header appends the header.
