How can spamtrap hits masquerade as bounces?

Spamtraps and bounces can be confusing:

Spamtrap behaviors vary:

Silent acceptance: Message accepted, monitored, no response. Delayed response: May generate DSN later. Immediate rejection: May look like regular bounce.

Why some spamtraps bounce:

Test sender's bounce handling. Observe if you keep sending. Evaluate list hygiene practices.

Detection challenges:

Cannot distinguish from real bounce. Address looks like any other invalid. No indication it was a trap.

Indirect detection:

Reputation drops without obvious cause. Blocklist inclusion without complaint spike. Delivery issues to specific providers.

Prevention remains key:

Assume old addresses may be traps. Remove long-inactive subscribers. Never use purchased lists.

Spamtraps are silent observers or disguised rejections. You often will not know you hit one until reputation suffers.
