Those errors have nothing to do with your domain. They mean that the PC from
where you did the nslookup has it's DNS server set to 206.111.47.3, and it
is unable to reverse-lookup that 206.111.47.3 to a hostname. After
complaining about that, it goes on to happily and correctly lookup the MX
for pcrush.com.
If the PC could telnet to you, doing an nslookup from that machine is really
a moot point anyway.
Exactly who can't get to you? Are we talking about clients at your site who
use you for their SMTP server? Or are we talking about people at other sites
who send mail to their own SMTP server and then get bounces back like below?
If there is another mail server involved, maybe you need to get that
administrator involved and look at it. Maybe it is having dns problems.
