Hi,

We are not able to receive emails from one company...

i am receiving this error.

The e-mail system was unable to deliver the message, but did not report a specific reason.  Check the address and try again.  If it still fails, contact your system administrator.

Hi Srini,

Is nnnnnnnn.com yours? Is that the address you're sending out from? And it's going to server removed?

There are no problems with your MX Record if that is the case. If the server refuses to accept your mail it would have to be checked from the recipient end.

How wonderful of them.

You don't have a problem sending to other recipients do you? I'm not quite sure what to tell you now, your MX Record is fine.

You have a minor problem in DNS where the servers authoritative for your domain have more Name Servers listed than the Parent servers say. See here:

http://www.dnsstuff.com/tools/dnsreport.ch?domain=alezzelom.com

However, all Name Servers listed (whether at Parent or not) respond with a correct MX for your domain.

We could assume the error message is misleading and check something else. When your mail server sends out a mail it sends out on a specific name. That name should resolve to a Public IP Address. And that Public IP Address should resolve back to the server name. Do you know if that's in place and working?
