localhost not defined - sendmail error
Customer can send mail on the local machine to other users on
the same machine.
He can do this on any of three machines. He cannot send mail
between machines. They are on the same subnet.
Sending to COMMO for sendmail support
Env: AIX 3.2.5
Desc: Customer is not able to send mail btw. two machines.
What's the deal?
Action: We called the machines - machine1 and machine2. After
seeing that the hostname is configured correctly on both
machines, they are both running DNS and the sendmail daemon
are active, we checked the sendmail.cf file.
For both machines the Dw, DD lines were correctly set. However,
nothing was set for the Cw line, but the line was uncommented.
We place the hostname and FQDN for each machine in their
respective sendmail.cf files, recompile and refreshed sendmail.
Now machine 1 is able to send mail to machine 2, but we can't
go the other way. Machine 2 registers the error:
localhost not defined
when we use mail -v root@\
On machine 1, when we try to resolve the name of machine 2
we don't get the FQDN for machine 2, but only its hostname
(which means the data is comming from /etc/hosts and not
DNS database files). We entered the name and address of
machine 2 in the named.data and named.rev files, respectively.
Now mail works from machine 2 to machine 1.
Next Action: CWCA
Test Case: none.
