Someone elses MX records point to our IP

[LizardKing]

Thanks to BT we have a static ip that seems to have previously been owned by another company that have failed to update there MX records for one of there domains.
Not the worst thing in the world as its just being bounced by our firewall!

However is there anything we can do to get there dns amended? tried emailing them but that seems to have fallen on deaf ears.

Tempted to just accept the mail and start replying to them as there is still a rdns entry on the ip

Are you sure that your email to them isn't just one of the things bouncing off your firewall (having been directed their by their MX record) ?

Nah, this is a completely different domain to there primary domain, but still very much related ie overclockersgroup.co.uk

If the IP was BT before you had it they should be able to check the MX records for you.

Not BT, just an IP owned by BT but assigned to one of there customers previously

Who's the DNS hosted by? Is it BT? If so, try pinging [email protected] a mail.

If they can't help with forward, they should be able to help with the reverse (if it's even set up).

Else it's a WHOIS job, and maybe try pinging them a line to get in touch with the customer?

Tempted to just email there ceo (if i can find them), might get a better response as there whois info is hidden, might be worth his while knowing there will be customer emails getting lost. I doubt the dns host would be interested in hearing about a misconfiguration on one of there customers from a complete stranger.

I ran a smtp trap for a while and although for the most part it was spam there was most definitely legitimate email in there!
