Just got a strange problem.
All of a sudden the server can't resolve outside hostnames.
Have checked resolve.conf it is OK
If i ping them here from laptop the respond.
If i ping fx. google.dk the server replies after LOONG time:
PING google.dk.syd-data.dk (126.96.36.199) 56(84) bytes of data
I discovered the problem because when i sent mail trough server they got back like this: 450 4.1.2 <firstname.lastname@example.org>: Recipient address rejected: Domain not found
If i tail maillog it says fx
Jan 20 16:22:03 naja postfix/smtpd: warning: 188.8.131.52.bl.spamcop.net: RBL lookup error: Host or domain name not found. Name service error for name=184.108.40.206.bl.spamcop.net type=A: Host not found, try again
Have tried to reload bind, AND tried to restart server
What is wrong??
Forgot to say, the server recieves mails, and reply to all requests
Resolved... dont know how.. was sitting and trying to ping different host, both by names, nad by IP.
And all of a sudden, everything responded as it should??
Anybody have any ideas??
