Start with org.dromara.email.jakarta.core.service.MonitorService, especially startListening at lines 58, 98, and 122, and trace the IMAP folder-opening path shown in the stack trace. Reproduce the listener with the affected mail account and determine the expected handling for the provider's “Unsafe Login” response; the issue is done when the intended monitoring behavior is verified without this failure.
