Emails sent to Gmail Addresses bounce with "no such user", sent to others fine.

Done a bunch of googling but so far no joy.

When we send emails from cPanel/Exim to people who are using GMail/Gsuite email, messages often bounce back with a "no such user here" message, even though the email address is correct. The bounce message is:
----
[email protected]
No Such User Here Reporting-MTA: dns; stan.ourdomainname.com

Action: failed Final-Recipient: rfc822;[email protected]
Status: 5.0.0
----

If I use another host (like mac.com) to send emails to the email address ([email protected]), the message gets through.

We've double-checked SPF, DKIM & DMARC and they all seem to be correct via MxToolbox and a couple of other test sites. ReverseDNS checks (via MXToolbox) all pass. We've tested email via all the spam checkers as well - they all pass.

Not sure how to fix this.

HI @aguynamedphil

That seems pretty odd that you'd receive that specific message as well. Have you confirmed that the transaction in /var/log/exim_mainlog indeed shows it reaching google? Also, what nameservers do you have in /etc/resolv.conf?
