you should check mx records in dns and mail server logs, or check with cwp support

here is a good site for dns testing

I have the same problem, my clients can only receive emails from each other, but they cannot receive any from other domains

Well I have already solved my problem, I just had to rebuild the mail server and everything is back to normal.
