Mail not shows in inbox

Hi i have installed virtualmin with postfix and dovecot and other stuff, when i send email it done successful, but at destination there is no email in inbox,



Aug 20 06:21:30 Local-Linux postfix/smtp[11536]: 68DD52F8488: [13], [14],
relay=none, delay=0.39, delays=0.23/0.14/0.02/0, dsn=5.4.6,
status=bounced (mail for loops back to myself)

It looks like there's a configuration issue somewhere. In the above example, is "" on your server, or another server?

It looks like the DNS settings for "" resolve to your server, but that your server isn't configured to receive email for that domain.
