OK.  So then how can we explain the difference in behavior between
messages going to recipient 1 and recipient 2, as described above?

Recall that both of them are getting identical SPF failures, but that
one of them properly passes the failed message to the courierfilter (as
specified by the three "BOFHSPF*=all" settings), and the other one
bounces the message with a 417/517 error.

The messages are identical.  The senders are identical.

The only difference I can find so far is the presence of the
localmailfilter in the account of the one that is causing the SPF
failures to bounce without feeding them to courierfilter, and the lack
of a localmailfilter for the other account.

What could I be overlooking?  What could be causing this?
