VERP Bounce Tracking & The 3-Strike Rule.
Legacy systems make a devastating mistake: they treat temporary server glitches as permanently dead addresses. SaaS Mailer uses Variable Envelope Return Path (VERP) and RFC 3464 DSN status codes to differentiate temporary soft bounces from permanent hard bounces.
User unknown (5.1.1) or domain does not exist. Address is immediately added to the tenant suppression list and contact marked bounced to protect sender reputation.
Mailbox full (4.2.2) or server busy (4.4.1). Soft bounces 1 and 2 increment metadata counter while keeping contact active. Only on the 3rd consecutive soft bounce is the address suppressed.
