## What is a blacklist?

Due to the prevalence of **spam** in our online world today, there are a number of publicly available resources on the internet that list servers that have been identified as sources of spam activity. These lists, commonly referred to as **blacklists**, are used by many email providers to reduce the amount of spam received by their users.

## Is my server on a blacklist?

In this context, abuse usually means the server was used to distribute spam. The bounceback message means the system has identified you as a source of spam based on one of the available blacklists.

If this is the case, you can [use our Bounceback Message Parser to learn more about the error](https://www.inmotionhosting.com/support/tools/bounce-back-parser/).
