mail bounced due to web server IP listed
« on: April 09, 2015, 10:05:55 PM »
Hello,

I got the bounce back like

Remote host said 554: mail is rejected due to [Webserver IP] is listed in CBL. But my mail server IP is different.

It is strange. How it is possible?

Make sure that it is not using your web server's IP address to relay email. Also, you should find the reason why CBL is listing your web server's IP address.

Thanks Kailash,

How can I determine that which IP is being used for the relay. Also, do you have any idea how can we find the reason for IP blackilst?

any help will be appreciated.

That depends on your mail server. Many RBLs provides evidence for blacklist. If your IP address is listed in CBL, you should get the reason from CBL IP lookup.
