Postfix has no way of knowing saslauthd has failed when cyrus
reports authentication has failed. Changing this would
require code change in cyrus.
So postfix options here are rather limited, and are not
without drawbacks.
If your clients connect on a specific port that always
requires authentication such as the submission or smtps port,
you can set "-o soft_bounce=yes" on that port in master.cf.
This turns *all* rejects on that port into 450. Obviously
this isn't appropriate for a general MX setting.
Or just stop/start postfix when you restart cyrus.
