I noticed this posted on another forum:

<quote>
It should be noted that reject_unknown_client_hostname will check only
the first PTR record returned for a host. So, you might reject
well-configured (i.e. RFC-compliant) clients whose matching PTR record
unfortunately isn't the first one in the list.

Is this factually correct? If so, what are the statistical chances of it
occurring? If correct, other than not using that option, what other
options should be used to prevent such an occurrence?
