Thanks.

So ... could you or someone explain what exactly is the nature of this
corruption?  I'd like to be able to somehow detect it programmatically,
if possible.  There definitely are two consecutive newlines in the
original message between the last line of the header and the start of
the first multipart separator, so I know that it must be something other
than that.

Thanks again.

More than likely the first blank line in the message wasn't. It contained a space or some other unprintable character. So, Courier kept looking for the blank line that delimits headers from the body, and inserted the SPF header there.
