If you are one whose IP has been black listed, each Blacklist has its own procedure of getting your IP removed from the Blacklist. In most cases a hosting service is notified that potential spam emails are being transmitted from their server.
It’s not uncommon for a mail IP address to end up on a public blacklist, especially on a shared server. It could be due to overall volume of mail coming from that server, or messages seem to have characteristics of spam in them.
Another common cause is email forwarders. If you have [email protected] forwarding to [email protected], if [email protected] is spammed, our mail server could forward that onto Gmail. Their servers might see our mail IP address as relaying the spam message to their server.

Blacklists allow them few days to clean up and they later remove accused IP from their list.
