Why is that?

Surely you should do the greylisting test first, and if something is
greylisted, don't even call SA.  Just do action_tempfail.  (That's what
our CanIt products do.)

I am seeing a lot of these.  From today (edited log extracts: sender, subject):

and greylisting seems to stop them.  The two networkone at ins-path.com
senders were still greylisted, because the second one was for a different
recipient than the first (same sending IP, though.)

David.
