Here is a comment on the web site www.dnsreport.com When you check a site on this web site the first revdns check can fail and the explanation is as follow
-------------- Reverse DNS entries for MX records This may be a false positive due to the nasty BIND bug (client side) that causes reverse DNS entries to fail the first time (if you ever see long delays in reverse DNS lookups, that's because of this bug). You can double-check using the 'Reverse DNS Lookup' tool at the DNSstuff site. ------------ I have too many timeout when cheking the first time REVDNS for non-existing revdns .

(hotmail.com) However the messages hasn't failed the SPAMDOMAINS test. For example from the Sender-IP: 218.25.255.18 Can it be, because it's not possible to finish the REVDNS-query? http://www.dnsstuff.com/tools/ptr.ch?ip=218.25.255.18 Question? If it's so, that a timeout in a REVDNS-query doesn't trigger the test, can we change this, so that a timeout triggers the test? What if a query for a legit sender-IP times out? Why a REVDNS-query can time out? Isn't so, that any reachable IP is assigned to someone?
