But rDNS isn't without issues too ?

>From http://searchcio.techtarget.com/sDefinition/0,,sid19_gci917504,00.html:


Reverse DNS (rDNS) is a method of resolving an IP address into a domain
name, just as the domain name system (DNS) resolves domain names into
associated IP addresses. One of the applications of reverse DNS is as a spam
filter. Here's how it works: Typically, a spammer uses an invalid IP
address, one that doesn't match the domain name. A reverse DNS lookup
program inputs IP addresses of incoming messages to a DNS database. If no
valid name is found to match the IP address, the server blocks that message.

Although reverse DNS is fairly effective for filtering spam, it also
sometimes blocks valid e-mail, at least in the current technological
environment. A number of problems, including network delays and improperly
configured networks or servers, can prevent legitimate messages from getting
through the filter. In January 2003, AT&T WorldNet started using reverse DNS
in conjunction with other anti-spam software. The company was forced to
remove the filter just 24 hours after it was deployed, after subscribers
reported that messages were going undelivered.

So has the problem that AT&T WorldNet been fixed or is that still an issue ?

Thanks,
