Postfix sends the client sending the email a temp-fail, which then sends an
error back up to the end user that their mail was not accepted for
delivery. If the email client itself doesn't have a queuing mechanism
(mine does thankfully), then they essentially have to throw their email
away, or keep trying to send it until the milter is back in service.

Right... instead of sending the client a temp fail. Not that it matters
now, since I have a working alternative. :)
