A delivery loop was detected which causes this email to be undeliverable.

So I am working for a company and they use Google Suite as a workspace to manage emails. However, we use cPanel as well for email forwarding.
I came across an error " A delivery loop was detected which causes this email to be undeliverable. " on an email that was created a long time ago on cPanel. The forwarding email worked and stopped working at some time. There are two emails configured to forward to, but only one work. I checked the forwarding email and tried to detect the problem why it keeps detecting a loop, but I can't seem to figure it out.

I have also noticed that since we are using Google Suite, creating new Cpanel email accounts' inboxes doesn't work.

How can I fix this issue? And where can I see the list of emails configured to be forwarded to? I have already checked Email Forwarders in Cpanel, and there's n email, but it simply does not forward to that email, instead it forwards to a different one.

Hey there! The best place to check for forwarders if you aren't finding them in the interface would be in the /etc/valiases/domain.com file. That will store any forwarders for the domain.

You could also try checking the /var/log/exim_mainlog file directly to see if you can get more details on how the specific email is being processed.
