Why can't I receive domain authentication emails from Shopify?

Topic summary

A user purchased a domain through Shopify and configured a Zoho email as their sender address. DNS records appear correctly set, and the Zoho email works normally with Gmail and Outlook.

Core Problem:

  • Verification emails from Shopify never arrive at the Zoho address
  • Store contact form submissions also fail to send
  • No emails from Shopify reach the inbox or spam folder

Technical Details:
Shopify staff found error logs showing “unable to get mx info: failed to get IPs from PTR record.” Zoho confirmed they received nothing from Shopify servers, suggesting Shopify has blocked their servers. The issue appears related to MX records or A record IP configuration, though DNS settings match Shopify’s specifications exactly.

Current Status:
Shopify acknowledged the problem is on their end and is investigating, but no resolution has been provided. The user is considering requesting a domain refund. Another user later reported experiencing the same issue, indicating this may be a broader problem.

One commenter initially suggested a domain name mismatch in the sender email address, but this was confirmed as just a typo in screenshots.

I bought the domain for my store directly from shopify, everything is set correctly and i have a Zoho email to use as a sender email. I already configured the DNS part and it all seems correct, also I can send and receive emails with the Zoho email with no problems at all for examples from Gmail and Outlook. The problem is, I am not able to receive the verification from Shopify to confirm i have access to that email and use it as sender email. I click the button a million times and i receive nothing, also i tried the Contact form from my store and nothing is being sent. So basically anything that is sent from shopify does not really get sent. I contacted both Zoho and Shopify, the problem seems from the Shopify end, something is wrong and they’re looking into it but i received no response and i need ir solved or i will problably claim a refund for the domain since i bought it from Shopify.

one of the staff when they checked the logs, this is what they saw; unable to get mx info: failed to get IPs from PTR record: lookup : unrecognized address". But the mx info is set correctly, i checked the Zoho and i copied and pasted exactly the records. I also added others records that Shopify specified to add. The problem is with the MX records or the IP of the A record or something, but it’s definitely Shopify since the email works correctly. Also i did not receive any emails in the spam folder and when i asked Zoho they checked the logs and they received nothing from Shopify in their servers, so its blocked in Shopify.

You have your “sender email” within the “notifications” settings on Shopify set to “info@glacifystore.com” … but your domain name is “glacifyshop.com”.

So the email should probably be “info@glacifyshop.com”.

You’ve entered an email address that doesn’t match your domain name.

I did correct it but still nothing, it’s a typo in the screenshot since i kept changing it… but still not working :confused:

Were you ever able to fix this? I have the same issue.
