OK, I guess it was my misunderstanding of exactly how sendmail works.  :-(

I'd assumed that fetchmail would direct all mail, regardless, to my inbox, 
which I now realise it is.  What I didn't know, was that even though sendmail 
*is* trying to deliver it locally, it still validates the sender domain.  So, 
it was a validation that failed, not an attempt at sending that failed.

Thanks for the explanation.
