One of our users gets systematically bounced back. Contrary to what the error received states, the user does indeed exist.
Examples follow. The user tried sending just a few emails today.
Is there anything we could do on our side? This seems to be an issue with Zoho mail, in my opinion.
Delivery to same target email from another user on our very same domain work as expected, the issue seems to be linked to this particular user of ours.
Best regards and thanks,
Michele Fadda
