If I check website at intodns.com I always get error on Reverse MX A records (PTR) after I set the following MX records to G Suite (old Google Apps):

  • 1 aspmx.l.google.com
  • 5 alt2.aspmx.l.google.com
  • 5 alt1.aspmx.l.google.com
  • 10 alt3.aspmx.l.google.com
  • 10 alt4.aspmx.l.google.com

Result:

enter image description here

  1. I have a dedicated server, the rDNS are set and have no errors till I do not declare MX records to G Suite.
  2. The error persist after 72 hours, so is not about a propagation issue.
  3. Doesn't matter if I keep the rDNS set by Data Center or if I set the rDNS to point to domain. The same error!
  4. SPF / DKIM are set for that domain.
  5. In WHM Email Routing set to: Remote Mail Exchange.

Email work correctly via G Suite, no errors or spam issue when sending and receiving emails!

What is funny that even Google.com receive the same error at intodns.com/google.com

Anyone able to set MX records to G Suite and to do not get this error?

  • I've never needed reverse DNS to work for my website. I don't think you need to pay attention to that error to get your website working. – Stephen Ostermiller Sep 14 at 11:42

This is a known thing https://serverfault.com/questions/915142/reverse-dns-does-not-match-smtp-banner-g-suite -

Here is a long explanation that rDNS is not required for every device https://serverfault.com/questions/612833/do-internet-standards-require-reverse-dns-for-every-device

I was curious about this and had a look at the rDNS of some domains using gsuite that I manage as a webhost and found the same warning. It all works. I am not concerned about it.
