no route to host

[gchen]

Hi,

I fired up some email by sendmail but they were not sent out. when i checked mailq, i found they are all in the queue and commented with "no route to host".

Can anyone shed some light for me? I am using a linux box.

Thanks!

Gary

This is more than likely a network problem.
Can you traceroute mail.destination.com ?
If so
Can you telnet mail.destination.com 25 ?
If so
What is the output of sendmail -v -q mail.destination.com ?
RU running IPchains/IPtables on your Linux box ?

traceroute is working fine.

telnet to port 25 seemed to be okay. it did not ask me for login username password etc and i do not know much about telnet to sendmail. only thing worked for me is "quit" from there.

the output of sendmail -v -q is basically sending all those message in mailq and the results were all "No route to host".

I have no IPchains nor IPtables in my linux box.

And what I was trying to do is simply --

/usr/sbin/sendmial gchen@mydomain.com < my_message

and it went to mailq and never went to outside world.

Help please! and thanks a lot!

Check to see if your servername is in /etc/hosts file or in the DNS server depending on your setup. Check your resolve order in resolve.conf

Another possible explanation is bad or delayed hoststatus info.
Run sendmail -bh
Then sendmail -v -q
Does this deliver the mail & clear the queue?
