Can your box resolve hostnames? What do you have in /etc/resolv.conf ?

Neutcomp,

Looks like it may be DNS related.

What does:

etc/resolv.conf

It says name service error. If Postfix can't get the MX record details from DNS it will fail. You'll need to emerge the tools, as suggested, to test the DNS.

I generally run Bind on the machine that has Postfix. Just as a caching DNS, nothing fancy.

Ok I have emerge bind, but I really dont know what i can do with it or how I could use this.
Can you help me out with that?

And I could not find a package to emerge nslookup. But maby this tool is compiled in another package?

Thanks
Bjorn

For nslookup and other things you'll want bind-tools as suggested above.

For Bind - run /etc/init.d/named start to start the nameserver.

Edit /etc/resolve.conf and put 127.0.0.1 as the first nameserver.

The result from nslookup -query=mx xs4all.nl

It sounds like your modem is supposed to be doing dns proxy only it isn't working or something. Can you find out what [caching] dns servers are provided for your use by your isp? Then you could just add those to your /etc/resolv.conf . If your apache/php/postfix server gets its ip address via dhcp you'll have to configure it not to overwrite your resolv.conf.

You seem to be having a permissions problem. It needs to be able to write to /var/run as user named to create the pid file.

Ok and how can I give that user write permissions?
Sorry for all those simple questions but I really dont know how to do that.

Thanks

Here's my /etc/bind/named.conf.

Yep the bind problem is fixed now thanks. But I still get the same MX problem when I send a mail.

magic919 · Posted: Sun Jan 01, 2006 8:23 pm Post subject:

But is Postfix using your newly-emerged DNS server? Can you run nslookup and check it is using 127.0.0.1, for example.

I had simular problems, but after i put

nameserver 194.109.104.104
nameserver 194.109.6.66

and removed nameserver 10.0.0.138
in /etc/resolv.conf it worked

(my primary DNS and secondary DNS server, read from the speedtouch modem, i have xs4all too)

an 'emerge bind-tools' solved this postfix problem for me!

i think postfix needs 'nslookup' which is part of the bind-tools.
