Prev: timeout writing message to hostname: Broken pipe
Next: Sendmail 8.13.6 bouncing mail on ldap_bind failure.
From: McHenry on 29 May 2006 03:16
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:
to=username(a)ourdomain.com.au, ctladdr=<fax(a)declan.office.ourdomain.com.au>
(78/78), delay=1+17:39:39, xdelay=00:00:00, mailer=esmtp, pri=3943029,
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:

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

This appears to be a temporary failure, see below...

Which may show that DNS is not the culprit.

So you have a route to the host, DNS resolves correctly (at least at my
place :-) )

;; ANSWER SECTION:
mail3.zoneedit.com. 916 IN A 216.133.67.106

;; ANSWER SECTION:
106.67.133.216.in-addr.arpa. 38400 IN PTR mail3.zoneedit.com.

I guess mail3.zoneedit.com does not want to accept icmp echo requests :-(

but...

luna > telnet mail3.zoneedit.com 25
Trying 216.133.67.106...

If you do the same tests from your mail server and find different
results, please post them (not to 3 different lists please).

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.
