Undeliverable message when sending email

Hi Experts,

I'm getting the following NDR back, I need some help with identifying where the problem lie?
The person I'm trying to send to put as "recipient.email@somewhere.com" to hide to original email address and my email (the sender) and put as "my.email@somewhere.com"
I suspect the issue is at the recipients end, but would need to understand how you can see see that based on the NDR log below

Hi,

The answer lies with your recipients mail server, the hint is: #5.4.6 smtp;554 5.4.6 mail loop detected.

They appear to have forwarding to another location which in turn is configured to route back to their mailbox, either with a client side or server side rule.

Best to get in touch with their IT team and mention "error 5.4.6 mail loop detected"

Hope that helps.
