I am trying to send mail from Exim but getting the bounce back.

013-03-28 13:05:06 1UL7MX-0007Vn-Oo ** jason@jkwind.co.kr: all relevant MX records point to non-existent hosts

the MX record of my domain is
hbl.in. MX 3600 5 c.mxscan.net4india.com.

Kindly help me in that

Hi,

It appears that the receiving party is unreachable. If you try telnet towards their mail server you get a connection refused.

Did you try sending an email to another destination, gmail, yahoo or msn perhaps?

I am able to do the telnet and all and from gmail i am able to send the mail

So since the server is back up, have you tried to send the email again? And are you sure the name is correct??
So if you're able to send mail everywhere EXCEPT one destination, wouldn't it be more logical to assume that that ONE destination/address is having a problem, rather than your mail system being broken??

Can you please confirm me why i am getting this error only
"all relevant MX records point to non-existent hosts". what does it indicate and if this error come what is to be done

To be blunt, it basically means that the destination domain you are trying to reach has broken MX records. Hence the question did you try and email anything else. There could be a lot of different problems going on because there are a lot of steps involved.

That's why we try to rule things out.

If you tried to look up that message, you'd find lots. Whatever MX records the DNS query returns aren't valid, so you've got DNS issues. Where are you getting your DNS information from? This is separate from where your own DNS information is hosted. And are you pointing to an internal or external DNS server? And if a domain fails, use NSLookup to see what MX records are returned. It could also be that you have some cached lookup information that isn't being updated, so flush your DNS cache too. Essentially, do basic diagnostics, and try to look up errors.

AGAIN: if you are able to send mail EVERYWHERE but one domain, then there may be a problem with that domain, NOT WITH YOUR EMAIL SYSTEM. They could have you blacklisted as a spammer, wrong address, changed their domain name, or could just be having server problems. Have you tried to resend, as suggested? And as you were told before, exim is NOT RECOMMENDED for RHEL:

You seem to have ignored that advice, installed it anyway, and are now surprised you're having problems.
