Abstract: A secure electronic mail system (100) and method mitigate unsolicited messages and mail-flood attacks using recipient-specific admission control before complete message-body acceptance. An ingress gateway (104) obtains bounded envelope metadata, while an identity and challenge controller (106) establishes a verified sender binding and issues a short-lived cryptographically authenticated admission lease bound to a recipient, transaction and message-size class. A distributed admission ledger (108) allocates bounded recipient-capacity sub-budgets among gateways and prevents replay or duplicate redemption. A recipient-state engine (110) evaluates traffic pressure and decaying sender trust, and a bounded delivery scheduler (112) reserves delivery capacity before message acceptance. Messages are admitted, challenged, deferred or isolated according to lease validity and available capacity. Delivery, rejection or expiry atomically settles each reservation, and restricted emergency sub- budgets support controlled operation during ledger disconnection. Accompanied Drawing [FIGS. 1-2].
