Can you post the contents of /etc/hosts? Also /etc/postfix/main.cf.
A couple of other questions - are you using transport maps, or do
you have a relay host configured? Also, are you using a program such
as dnsmasq that may be redirecting things strangely?

The default bind install should behave as a caching only server. Does
it not do so? (I haven't tested it, I have a proper nameserver
already setup on my local network.)
Another option is the dnsmasq package. It should be simpler and
smaller (resource wise) than bind.

I have NM with static IP working just fine. Using the GUI may or may
not be causing the problems (as in, not writting to correct files or not
getting it correct or whatever), but you can try to get around it or
using a little simpler way to help? Try running
"system-config-network-tui" and that should write the correct info. Then
edit /etc/sysconfig/network-scripts/ifcfg-eth0 (or whatever your using)
and make sure your IP, netmask, gateway, etc stuff is correct. You also
need your DNS info in there as well so NM can pick it up. If using NM,
it overwrites resolv.conf when it starts/stops, so no use editing
resolv.conf manually.
Here is a sample of mine with minimal stuff that works if it helps..

This problem turns out to be a "slow response" DNS problem. The FAQ
contains a clear solution which worked immediately for me.
The FAQ entry also contains a pointer to _this bug_:
https://bugzilla.redhat.com/show_bug.cgi?id=459756
which has more than 70 comments, many of which are complaining about
why this bug has so far not been fixed. For many, this bug is
rendering F10 useless. Indeed Chris Terpak (comment 71 in the bug
report) says it very well:
I pulled my hair out trying to find this. IMHO, this bug is not a
'medium' priority - it makes F10 useless. I disagree that users should
have to go and try and find downstream software that uses glibc when
it is glibc that changed (and I read every entry in this
thread). F6,7,8,9 were all fine on the exact same hardware.
This should be critical priority not medium. Forcing a user to install
BIND or DNSMASQ as a work around is utter nonsense.
I couldn't agree more.

Question about enabling a few services.
by Steven W. Orr
The following are disabled on my system and my stoopid question of the day
is whether they should be enabled or not. (Obviously I'm not sure what to
tell you to make much of a comment, but I'm hoping that maybe some of them
are just plain innocuous and should be enabled for everyone.)
* dnsmasq (Will this speed me up?)
* multipathd (No idea)
* netconsole (I'm guessing no because there is not remote syslogd
accessing my box)
* Should I be enabling both network and NetworkManager or should I only
have one or the other. Currenty they're both on. Two NICS, one dhcp to my
cable modem and the other with a hard address to another 'puter.
* pcscd (I don't have a PC/SC lite and Musclecard frameworks that I know
of)
* psacct (Is this good to have?)
* smolt (Same thing. Is this A Good Thing?)
* squid (Would this somehow speed up my browser?)
I come from the old school that says to disable everything you don't need,
but I'm not sure what these things do.
TIA

should be ok though I would probably just use 'network' - I hate to
recommend to you to fix something that isn't broken. 'network' could
handle the dhcp connection to the cable modem but you would have to
tinker...just to shut off network manager.

I think that the general idea is to leave stuff alone unless it starts
to make sense to use/configure it.

Getting DHCP to work/f10 declines to start network
by tom
I'm giving f10 a try on a new disk, and therefor a fresh install.
I'm supposed to be picking up (and was with f8) the ip4 address
from a dnsmasq server via dhcp, but f10 is barfing. Well, not
entirely, as the IP6 style networking shows on ifconfig, but since
I don't want IP6 networking at this moment, that isn't exactly
usefull.
Now since I dislike Network Manage on a desktop machine, and would
prefe to have the network come up during boot, what is the prefered
way to get rid of Netwreck Mangler (sp?), and bring the network
up the old fashioned way.
I'd love to see pointers or suggestions on trouble shooting this
type issue also.
And now to go pester fiend Google and find out how little I
understand 8-/.
Thanks for the assistance.

Disable 'NetworkManager' and enable 'network' service. You can do that
by running 'setup' on your shell. Then you can edit interface related
files in '/etc/sysconfig/networking/' to setup addresses. I am
suggesting this because, 'system-config-network' has some issues of
late.

I would be surprised if you needed either NIS or LDAP for a SOHO
network. However, I would say NIS and LDAP are similar, but bind (i.e.
DNS) serves a fundamentally different purpose.

Well, you won't /need/ to use it. You configure a server to assign IPs
(DHCP) and automatically tell other computers which computer maps to
which IPs (DNS).

Depends how small, of course. But I would think a simple DNS/DHCP
server like dnsmasq is reasonable for such a network. See
http://www.linux.com/articles/149040 for a good start.
