Hi,

I'm writing in to see if anyone had encounter this problem before.

I have 6 AIX servers of oslevel 5.2.0.0. I was recently asked to change the /etc/resolv.conf to reflect the change of domain from DomainA(abc) to DomainB(aaa.bbb.com). Out of the 6 servers, 3 of the servers seemed to be still reflecting the old domain behind the hostname.

Correct domain:-
hostname.aaa.bbb.com

Wrong domain:-
hostname.abc

I schedule a script everyday to auto send email to check on the diskspace util.
However, the 3 servers still reflect the wrong domain in the sender field.

Correct Sender:-
root@hostname.aaa.bbb.com

Wrong Sender:-
root@hostname.abc
Can anyone please help advise? Any form of help will be appreciated very much.
So far, I had only edited /etc/resolv.conf
Am I missing out some other files?
The script as follows:-

#!/bin/sh
hostname=`hostname`
reciepients='email@email.com'
df -m > /jobs/mailtxt
mail -s "Disk report - $hostname" "$reciepients" </jobs/mailtxt

By any chance is the email in question being routed to you via a non-AIX MTA, Exchange or something like that? If so, it may be the case that the MTA is inserting or changing the hostname based on DNS as seen from its perspective. I know in my shop I have to fill out a request form the get this done and it insists on a FQDN even though I don't always use them on UNIX systems. The results I get seem to show little or no relationship to the way things are defined on AIX or Solaris.
