Why are you trying to REDIRECT the mail? You dont need to REDIRECT it. All you need to do is to read it yes? Did you do the tutorials for EMAIL?
IF you REDIRECT it you are telling the server to bypass your mail on its current server and that another server will handle it. If you dont have access or cant set up a DOMAIN mail on that server it will NOT WORK.
Yes .. you can check your mail in cpanel. You login to cpanel and then go to webmail. Please do the tutorials here...
