550 5.1.1
We are having an issuing receiving all emails. We are able send emails but cannot receive.
We changed the MX records that the Google team suggested we change. Those changes solved the issue, but not entirely as we cannot receive all emails still.
The MX records are currently pointing to Google, to the exact MX records that Google are recommending at this time.
So, that part looks okay.
The error code “550 5.1.1” is referring to fact, that the receiving mail server claims that the email account you’re sending to (e.g. “john.doe” for “[email protected]”) does not exist.
So first of all, I would suggest to check for typo’s / spelling mistakes, such as e.g. “jon.doe” or “jhon.doe” instead of “john.doe” .
If that doesn’t lead anywhere, you will then need to research the problem with Google, such as e.g. why they are returning “550 5.1.1” to people sending messages your way, if the email account(s) actually do exist, according to the Google Workspace control panel.
Do you have any idea what else could be causing this if the MX records are correct or recommended by Google? Do we need to add or amend other records?
Did you even read what @DarkDeviL wrote above?
Why would anyone bother to offer you any more ideas when you totally disregard what you’ve been given already?
