So although the mail client says it was received by @icloud.com. When inspecting all the headers, I do notice my email popping up in there under Received:
fields (I’m not posting the details for privacy reasons).
I’m not sure why my email client shows me a weird receiver email. But at least now I know what address is getting spammed!
Cheers!
Go with what you want to do. If you prefer writing in one language over an other, do it.
