554 5.7.1 : Recipient address rejected: user [username] does not exist

Hi,

I mistakenly altered my shopify email settings (where my domain is managed), but immediately reverted them, however now I have a strange email issue.

I can send emails just fine, but cannot receive them.

I have tried all troubleshooting steps but nothing has helped.

Global MX records correctly point to Zoho.

When sending to any of my user addresses I am getting a bounceback with the error:

554 5.7.1 : Recipient address rejected: user [username] does not exist

(Where [username] is the email address)

I have even setup a catchall rule in Zoho and still get the same issue.

What else can I try? All records are correct in shopify, and all of the Zoho tools (and external ones) indicate that the records are correct. But my mailboxes are unable to receive email...

It has now been like this for around 5 hours.
