This blacklist significantly affects deliverability at many mail servers and filters.
About Backscatterer
Backscatterer lists mail servers that generate backscatter — non-delivery reports, auto-replies, or bounce messages sent to forged sender addresses in spam emails. This is considered a mail server misconfiguration.
Why am I listed?
Mail servers are listed when they send non-delivery reports or other automated responses (vacation messages, challenge-response systems) to addresses that did not actually send the original email, thereby distributing the burden of spam-related bounces.
How to get delisted
Follow these steps in order to request removal from Backscatterer.

- 3
Configure out-of-office or vacation replies to only respond to authenticated messages.
- 4
Check your listing at backscatterer.org.

Use the paid express removal at backscatterer.org or wait for the automatic expiry.
