Hi,

Our Admin want to know how to repare this problem. Any info?

If it's a Red Hat server then you should be paying RedHat for your support, escalate it through them.

Sorry - I missed in your prior post you were saying you saw "master" on a different host and that PID 2745 was on that different host.

When you ran "service postfix start" it didn't output anything include "FAILED"?

Is this in fact RHEL? Is is RHEL6? RHEL5? etc...?

The default mailer for RHEL6 is Postfix but on RHEL5 and earlier it was still Sendmail. You might want verify they're both NOT trying to start. Also check your /etc/alternatives to see what it thinks default mailer is.

The Postfix configuration is done /etc/postfix and the key file there is main.cf. You might want to compare differences between the working host and the one that isn't working.

(For sendmail the main files are in /etc/mail with the key one being sendmail.cf and sendmail.mc.)

To MensaWater:

We use RHEL5. But the mailer is already the postfix.

I've looked at the /etc/alternatives and I get:

Code:

]# ll /etc/alternatives/*mail*
lrwxrwxrwx 1 root root 22 Nov 15 08:03 /etc/alternatives/mta-mailq -> /usr/bin/mailq.postfix
lrwxrwxrwx 1 root root 38 Nov 15 08:03 /etc/alternatives/mta-mailqman -> /usr/share/man/man1/mailq.postfix.1.gz
lrwxrwxrwx 1 root root 22 Nov 15 08:03 /etc/alternatives/mta-rmail -> /usr/bin/rmail.postfix
lrwxrwxrwx 1 root root 25 Nov 15 08:03 /etc/alternatives/mta-sendmail -> /usr/lib/sendmail.postfix
lrwxrwxrwx 1 root root 41 Nov 15 08:03 /etc/alternatives/mta-sendmailman -> /usr/share/man/man1/sendmail.postfix.1.gz

These look the same as by the other machine where the mailer works.

I've copied the main.cf from the good working machine to this machine and reboot the machine. But this doesn't help.

There is no directory called /etc/mail

Further info:

Last week as we tried to extend a partion of /opt, there is a corrut. We have to repare it. After reparation some of files are deleted. I am not sure if some files related to mailer also deleted.

I solve the problem myself. I do followings:

yum remove postfix
yum install postfix

After re-installation it works again.

Ah cool, glad you got sorted.
