Incorrect "Your MX does not appear to have working RDNS" on Professional test

[timeggleston]

Hi all,

I've been banging my head against a wall on this one for a while. I can't get my MX to register as having a PTR entry in the Professional test despite the fact that it does (on the HE DNS service no less), and with a TTL on the records of 15 min I'm not sure why this hasn't cleared up by now -- it's been in this configuration for a couple of days.

Dig queries below. Same results are returned if I ask the HE.net nameservers directly. Any ideas?

Cheers!

Agreed...if I run the dig commands against HE, I get the same responses as you listed.

You might need to email ipv6@he.net to have them kick the server.

[timeggleston]

Thanks cholzhauer... it's good to see it's not just me being crazy! I'll send them an email.

[timeggleston]

That did it! Hurricane support flushed the cache and all's well; in fact because I was using HE's DNS servers I went straight through to Sage  8)

Great certification program!

Hi!
I have similar error message, but... If I understand correctly, I needed to set a PTR record to DNS. I tested IPv6 with a sub domain, ipv6.ipont.hu. The domain registrar is another company, and theirs admin interface can manage only "A", "CNAME", "MX", "TXT" records. What can I do? What's the solution? Or I have a wrong way of thinking...?

Thanks for your help

[cholzhauer]

Somehow you've already listed an AAAA address for ipv6.ipont.hu.  It looks like ipv6.ipont.hu is also your mail server

Now, you need to do a PTR record to point 2001:470:1f13:68b::1 at ipv6.ipont.hu

Yeah... The DNS admin panel have a "bug": example with Firebug I can rewrite form values. I did so AAAA record, but "officially" this isn't possible. I try this bug with PTR, but doesn't work.

Edit: OMG!! My question... sorry guys. I realize I had a stupid question...
