The way spamd works your message does not get handled by a real smtp
daemon until it clears greylisting, in contrast to the various
greylisting MTA plugins (postgrey which lives inside postfix adds a
rather verbose message to headers IIRC).  bsdly.net runs spamd, so
studying your logs or inbox to fish out any reference to the message
I'm answering now will produce the answer you are looking for.  Did
the delivery of this message produce anything you would rather not
have your friends or customers to see?

False postitives are bad, bad, bad.  I would not want to make any
sweeping assertions without studying your setup, but I suspect you are
either bit by side effects of a badly maintained blacklist or the
senders whos mail isn't getting delivered misconfigured mail servers
which do not retry properly.
