Give you use Cloudfare, suggest you contact them regarding the bad from address. If the receiving SMTP goes to lookup the domain in the from field and it fails, it will reject the email (spam reduction).

I'm having same issue on CS Cart 4.7.3 MV. Any fix for this?

Actually I found the solution. I didn't see the new function from CS Cart when I updated the site. It's new function that's on the email setting.

Great update to CS Cart!
