How Does The Truncate Blacklist Work?

Truncate Email Mechanism

The primary function of the truncate blacklist is to ensure email safety and prevent spam. When an IP address is suspected of sending spam or malicious content, the email can be truncated, meaning the recipient will only receive a portion of it.

When the truncate blacklist system detects an email from a blacklisted IP, it can either truncate the email or block it entirely. The “message truncated blocked” status implies that the email was identified as suspicious and was not allowed to reach the recipient.
