What you're referring to is your email server IP address being blocked by remote email servers using Blocking Lists such as CBL,
You will have to apply for delisting of your email server IP address using the information you receive in the bounce back from the remote email servers.
In some cases, you will not find a URL/web link for delisting. In that case, the issue is usually resolved automatically after the blocking list database removes your IP in a period of 24 - 72 hours.
Which MTA are you using btw ? In Exim you can also change the outgoing interface IP address so that all emails route through that IP. The IP address of the email server needs to have a rDNS(Reverse DNS) set.
