Ok, I'm out of ideas...Maybe someone here could help me. Here is my problem.

Somehow my sendmail.cf file turn into 0 byte and I can't start sendmail. So, I recreated sendmail.cf by running

m4 /etc/mail/sendmail.mc > /etc/sendmail.cf

then restart sendmail.

the new sendmail.cf fixed the problem. But, now all the outgoing email show the wrong email address. The sender address show cojo@mail.domain.com instead of cojo@domain.com. What am I missing on my setup? Here are my hosts and local-host-names:

hosts:
127.0.0.1 mail.domain.com mail localhost.localdomain localhost

local-host-names:
domain.com
mail.domain.com

cojo

As far as I know you don't need 'mail.domain.com' in local-host-names because it is already in your hosts file

Try removing it see if it works

Thanks Pete M for replying. I did tried removing 'mail.domain.com' from local-host-names file. But, it still send out with user@mail.domain.com'...

Hi cojo

Still trying to work this out for you, where does the word 'mail' come from is it the name of your machine ?

This is my /etc/hosts
127.0.0.1 server.mydomain.net server localhost.localdomain localhost

Server is the name of my machine this matches /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=server

What does this command give you ?

Mine answers 'server'

Might be worth a look at etc/hosts and etc/sysconfig/network

Pete

Mike M,

mail is the name of my server.

when I type hostname at the prompt. I get mail.domain.com

My network file contain

networking = yes
hostname = mail.domain.com

So, I changed it to match your. But, the problem still exist.....Thanks for trying to figure this out for me....John

John

Did you reboot the machine after making changes to /etc/sysconfig/network ?

Pete

not yet. I will reboot my machine and will let you know later....Thanks again...John
