Hi abbasiftt,
Well... Your issue is: "your host [168.187.83.138] is blacklisted by bl.spamcop.net. No mail will be accepted"
If you believe that your host IP should not be blacklisted, go to the spamcop.net site, enter your IP and request to be removed from their blacklist.
I would recommend checking your AV software as well as open relays on your Exchange server.
Let me know if you need more assistance.
Cheers

My pleasure.
Well, it says that it requires a prt record for your Exchange or smarthost. I would suggest that you ask your ISP to create a PTR record on their side that points to your IP address.
More and more companies do reverse lookups to try and minimize spam.

1.You mean, global IP that points to mail.domain.com?
2. Please let me know how to check the open relay in exchange and what to check AV software.

Ok, so I take it the PTR record points to your mail server and the name is correct as well?

Cool. Your server is secure, so you do not have to worry about an open replay.
Do you have Anti Virus installed on your network?
Do you have Anti Virus installed on your network?
ASKER
Yes, Symantec EP
And it's updated I take it?
How long before you're cleared from the blacklist? It's usually about 48 hours, if I remember correctly.

For the blacklist issue what I have done is I changed the IP of the gateway. after that mail went through.
But what could be solution for the second problem (mail bounced back with another error which I mentioned before). Now so many mails bounced back with same error (see error below)
Awaiting your reply.

When you changed your IP address, the PTR record at your ISP is no longer valid. You need to ask your ISP to change the PTR record to the new IP you have changed to.
ASKER
How to find out which PC is generating junk mails. Because now the changed IP is also blocked.
And the they sent me an email saying that if your request to unblock the IP comes frequntly they will block completely.To solve it you have to find and fix the PC/server which is generating spam.
Your help is highly appreciated.

Is your gateway responsible for sending the mail? I mean, is it a smarthost?
How many PC do you have in your organization? If not too many, I would suggest that you download and install MalwareBytes on each system and do a scan to see which PC is infected and is sending out the mail.
You can download it here:
http://www.malwarebytes.org/mbam.php
You can use the free trial version.

Good, your spam should stop now.
About the other error:
If you want your mail delivered properly the Official Host Name of the sending server should match the PTR (reverse DNS) of the sending IP Address, and there should be an "A" record that matches the OHN as well.
Example:
mail.yourdomain.com (Official Host Name) on 123.123.123.123
PTR for 123.123.123.123 should match mail.yourdomain.com (contact you ISP to do this for you)
There should be an A record in yourdomain.com pointing to 123.123.123.123
Problem will go away if you do the above.

I have configured it before on my last discussion with you. I think it is the same as you mentioend above. see below for the current settings.
mail.domain.com pointsto 123.123.123.123 (A record externallly)
mail.domain.com pointsto 192.168.0.222 (A record internallly)
mail.domain.com pointsto 123.123.123.123 (done by ISP) PTR
But let's wait for next working day and check. I think It will work.
