AI agent finds 29 of 31 WordPress sites claiming emails were sent when none left the server

My AI agent caught most of our sites saying sent while no email left the server

A developer's AI agent ran a real test on a client site's contact form: WordPress reported success, the admin panel showed the request, and the server accepted the message — but the email never arrived, stuck in a deferred queue. A scan of 31 WordPress sites on the same server found 29 with the same silent failure. The lesson: a function returning true is not proof a person received anything.

Every layer that reports back says yes. Only the inbox says no.
