I'm actually having the same problem all of a sudden. The problem is that the sender's IP address comes through as a separate header Received: from
How can we hide the sender's IP and only use the server's IP when sending messages?

This problem does not appear to be "outbound email is blocked by your server (not another server) because of spamcop and spamhaus" so I am moving this out of the Feature Request Discussions and into the Email Discussions section of the forum where you may find more appropriate advice.
If you're using cPanel&WHM 11.28, the Domains and IPs tab in the Exim Configuration editor may be a helpful first place to look.
