No route to host

We have a simple network:
a) One Linux server 192.168.1.1
b) One Windows workstation 192.168.1.12

Both access the internet via an ADSL connection: modem/router@
192.168.1.254.

The server runs the apps but does not run a DNS server, DHCP is handled by
the router.

The Linux fax server should forward faxes received to an email address
however this is not happening.

I have tried to diagnose this problem however have gotten nowhere and am
loath to start changing many setting in fear that I turn a relatively simple
problem into a complex one.

The following entry, and many others like it, are logged in /var/log/maillog

May 29 13:31:52 declan sendmail[6116]: k4RBqD69004136:

relay=mail3.zoneedit.com., dsn=4.0.0, stat=Deferred: mail3.zoneedit.com.: No
route to host

Our domain name "ourdomain.com.au" is hosted by zoneedit.com who forward
emails received to this domain to the ISP email accounts.

I understand from my research that this is not a sendmail problem but simply
a DNS problem however it intrigues me that the server has associated
ourdomain.com.au with zoneedit.com which implies to me the links are being
made correctly.

I can traceroute to mail3.zoneedit.com as per below:

I cannot ping mail3.zoneedit.com as per below, it picks up the ip address
but simply hangs:

[root@declan /]# ping mail3.zoneedit.com
PING mail3.zoneedit.com (216.133.67.106) 56(84) bytes of data.

The following is the resolv.conf file, not sure if it helps but may
assist...

[root@declan /]# cat /etc/resolv.conf
search ourdomain
nameserver 192.168.1.254
[root@declan /]#


Any help here would be greatly appreciated... thanks in advance...

Why do you think it's a DNS problem?

What happens if you do: telnet mail3.zoneedit.com 25

If there's a firewall somewhere blocking port 25, that would result in
"No route to host".

Quite odd. Perhaps your ISP is screwing about. Try a tcp trace. Upon
performing my own testing, it seems that mail3 is not responding
properly. Though, I detected no icmp response when trying to reach mail3
and that is what I would attribute the above error. Try resending and
monitor for icmp. Failing that, try sending to mail2.
