I am trying to set up email routing for my domain and I get the above error when sending test emails. The log show the following:
I don’t understand how the sender is being verified. It looks to me that the destination <rishworth.ca> is trying to verify the sender [email protected] at the site that is doing the routing <bwra.ca>
If someone can help me untangle what is happening and how to resolve it, I would appreciate it.
FYI, all three domains are managed by Cloudflare.
