mail not working on RHEL 6.4

Hello,
On one of the server, mail is broken and I am not receiving it in my inbox. Can somebody help me on this ?

Code:

root@client1 $> /etc/init.d/postfix status
master (pid  17328) is running...
root@client1 $> ps -ef | grep 17328

If you're paying for it, Red Hat can. You should contact them instead.

Probably, but since you post NOTHING that would let us help you, we can't. You don't tell us whether this is a new problem, has this EVER worked, and if so, what's changed?? All you've posted is that you have RHEL 6.4 and that postfix is running....nothing about your environment, either. I see a relay host in a VERY small config file. Did you actually compile/install that config file? Restart Postfix afterwards? Configure the relay to accept mail?

Also, you've posted many threads in the past where you NEVER follow up; hard to see why we should try to help when you don't follow up, answer questions, or post details.

This is not correct. Out of total 21 questions, 7 are marked as SOLVED, 6 had 'last' reply from my side and few others were discussed with my responses as well and in few, I was asked to refer knowledgebase or contact support. This is not point of debate, but I was trying to find, what I missed. I do not have support for all servers, which is management thing and thats why I am looking for that help elsewhere, to fix the stuff.

Regarding this issue, it was a start of thread and provided OS and config. I want to give more details, but I would need to know, what is needed for you guys to help me, apart from this 'small' config. I do not have support for this server and I posted this question in "Linux - Newbie".

I am not sure, since when it was broken, it came to my notice recently.I didn't compiled/install config file. Yes, I restarted postfix. Relay is configured to accept mail.

Sorry, no. You need to pay for support if you're going to use commercial products. Many, if not all, of your RHEL related questions have bugfixes/solutions posted in Red Hat's knowledgebase, and you can get the bugfixes/patches/updates by **ONLY BY PAYING FOR SUPPORT**. Your 'management thing' is immaterial; if you are responsible for those servers, then it is up to YOU to take action within your organization and get things supported.

Again, if you use CentOS, it's 99+% identical, but FREE, and you WILL get the bugfixes.

Again, you've been posting for years, and are (supposedly) the administrator for MANY servers, both VM and physical, Linux and Solaris. You've been here for FOUR YEARS, and are doing this job professionally...and you are now claiming to be a 'newbie'???? And it seems odd that *EVERY* RHEL server you ask about doesn't have support, while all the others do.

You aren't sure when it was broken or if it ever worked??? Are you the administrator or not? You should KNOW what's going on, since you're paid to make sure your companies servers are working, right?? And if you are an administrator, you should know how to do troubleshooting, right??? Do you have:

Log files?
Config files?
An idea of the network topology between the servers in question?
Knowledge of the software versions?
Knowledge of how to install and CONFIGURE that software?
How to test the upstream relay server to see what it is ACTUALLY DOING? As in: do ANY other systems relay mail through it????
How to restart postfix to pick up the changes to the .cf file. Hint:"service restart postfix" doesn't do it.

...BASIC troubleshooting things. Things you've been asked for many times in the past...nothing new.

Again: you have posted no details about your environment, log files, or any troubleshooting tests that would indicate you've performed any testing on the mail environment as a whole, to see if the relay server is working correctly. As the 'administrator', you should also be aware that the relay server has to be configured as well, to ACCEPT emails from various hosts, and that DNS needs to be working for both systems reciprocally.

@abhisheks77,

RHEL is a commercial distribution with paid for support. Please contact RedHat to help you resolve this issue.
