Linux - konfiguracija domene + sendmail

Konfiguriram sendmail in sem opazil naslednje:

root@SeRvEr:/# nslookup slo-tech.com
Server: 193.189.160.11
Address: 193.189.160.11#53

Non-authoritative answer:
Name: slo-tech.com
Address: 212.93.228.2

----------------------------------

root@SeRvEr:/# telnet localhost:25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 myright.net ESMTP Sendmail 8.13.3/8.13.7; Sat, 24 Jun 2006 09:51:43 GMT
quit
221 2.0.0 myright.net closing connection
Connection closed by foreign host.

-----------------------------------

root@SeRvEr:/etc# host myright.net
myright.net has address 193.77.151.8
Host myright.net not found: 2(SERVFAIL)
Host myright.net not found: 2(SERVFAIL)


Zanima me, kaj bi moral dati datoteko /etc/hosts, da bi vse skupaj delovalo kot mora.

Sicer je domena od zunaj dostopna, vendar pa ne dela sendmail (to me pa ZLO moti).
