Eurofigter rDNS not working?

[EOTB]

Hi Guys,

I have been testing mail being sent direct from my website hosting hosted on eurofighter and found that my ISPs mail server is seeing it as spam. I have looked at the headers for it and this is what I saw (with emails/domains ** out):

As you can see there is a message in there stating that the IP for eurofighter does not have rDNS setup and it looks to be the reason why it is seeing it as spam.

I have tried pinging the IP with the -a switch, but it does not resolve:

Is this something that can be resolved?

Thanks

This has been sorted now. You can verify same from http://webtools.eukhost.com/retrieve_host.php

Our DNS server had problem last night due to which some rDNS entries have gone wrong.
