[CentOS] Postfix problem with DNS

[Nigel kendrick]

Was your old DSL modem working as a DNS proxy but this hasn't been enabled
(or isn't supported or isn't working well) on the new one?

Can you resolve addresses on the server using dig?

Can you put the old DSL modem back in place to see if the problem goes away?

Today I have changed my DSL modem and problems with postfix begun. It
receives mail, but cannot send any. In logs I can read

Jun 22 19:39:53 server postfix/smtp[5040]: 9A51711FF85:
to=address at somedomain.com, relay=none, delay=12840, status=deferred (Host or
domain name not found. Name service error for name=somedomain.com type=MX:
Host not found, try again)

My resolv.conf is proper. I can ping any server, but postfix cannot see
them. What can I do ? Postfix 2.1.5

Best Regards
Kuba
