Can validation identify spam traps?

This is a critical distinction. Validation cannot reliably detect recycled spamtraps because these are abandoned inboxes designed to appear technically valid and fully operational. However sophisticated hygiene and validation systems can identify many pristine traps and typo traps by using proprietary internal databases of known trap domains patterns and risky address structures. These systems will never publish trap addresses but they will flag them as toxic or risky based on global intelligence.
