Can not receive mail.

I have a new VPS with WHM/cPanel and try to configure it...
I created a new account with hostname 162.210.xx.xx (I did not have a domain yet)
I made a mail box main@162.210.xx.xx, and I can send mails from webmail fine, but when try send mail to main@162.210.xx.xx I don't receive it.
What can be the problem?

In "Mail Delivery Reports" (on WHM) I see that every time I send a mail to main@162.210.xx.xx the mail is accepted (and I can read it from there), but in webmail I don't see it, so I understand that it goes to the wrong place...
