What does your outbound messages go through prior to the internet?

Is the DR server a mutlirole server or is only the MB role?

Can you check on the IronPort under Mail Policies > Sendergroup that the relayed mail flow policy has the DR Exchange Server IP

This is an IP address rejection. You need to figure out why it's being blocked, could be blacklisted, no or wrong SPF record etc...

But the emails are not even reaching the iron port its bouncing before reaching iron port when i check in the mail delivery reports

On your IronPort do you Messaging Tracking enabled?

Sorry just updating my comment as I seen that you stipulated that it is not even reaching the ironport, can you verify with the message tracking that you do indeed have email flowing through the ironport for the other users.

The other thing to look at as well is that the network for your DR site has access to communicate with the Ironport.

Your server is thinking that gmail address your sending from is a spam source.
You can add this address to white list on your server.
Open Exchange Shell and write this command

Set-ContentFilterConfig -BypassedSenders user@gmail.com

Now try to resend email and check if will be rejected.

Thanks everyone for your support i found the problem it was because the DR exchnage server was not added on the iron port for relaying emails,that is why it was not able to relay any emails externally,after adding the IP the issue got reoslved.
