current-users is probably the wrong list for this, but since your
return address isn't in DNS, I've posted here so you'll get the word.
netbsd-help or netbsd-users would probably be better. (current-users
is for development of the current user-space software).
If you have only one machine at your site, you probably do not need
to run named.
Regardless, there should be listings in /etc/hosts. Your resolv.conf
specifies a lookup in /etc/hosts before turning to DNS.
The problem is, what IPA besides 127.0.0.1 will "starwolf" have?
Are you guaranteed the same IPA (static IP, so-called) from the ISP?
Or are you 'rolling your own' from the reserved set (10.x.x.x et cetera)?
I guess the question is, what's in /etc/hosts?
I notice that "starwolf.com" (your return addr) is not in the DNS.
Unless it was registered recently, I suspect a problem somewhere.
(You should probably be masquerading your mail as "idiom.com" or wherever
you get your mail, if s'wolf is an unregistered domain)
The nameserver you list:
server 220.127.116.11 (a.root-servers.net) is a *root* nameserver, which you
should not be using this way, as a general purpose nameserver, even
as a fallback. (It cannot resolve anything, loosely speaking).
The other server, 18.104.22.168, has its own set of problems:
[root@lucy bin]# nslookup 22.214.171.124
[root@lucy bin]# nslookup
Default Server: lucy.loco.net
> server above.idiom.com
*** Can't find address for server above.idiom.com: Non-existent host/domain
[root@lucy bin]# telnet 126.96.36.199 42
telnet: Unable to connect to remote host: Connection refused
[root@lucy bin]# (note, the machine did answer a ping).
Doesn't look like a nameserver, or it refused me because my IP is denied.
(Which is a misconfiguration, isn't it? Shouldn't an RFC compliant nameserver
accept connections from anywhere? How else could it work?)
So, off hand, you have troubles, which should be resolved with your ISP.
