justin	97f6a08183	Bind email verifier to secondary IP (.72) for SMTP probes ... Campaign emails send from .71 via Postfix (now explicitly bound). Verification RCPT TO probes go from .72 to protect sending reputation. Configurable via VERIFY_SOURCE_IP env var.

justin	ed0a44645e	Email verifier: add catch-all domain detection via random probe ... Before checking the real address, sends a random 20-char address to the domain. If the server accepts it (250), the domain is catch-all and individual verification is meaningless. Result cached per domain. Existing known catch-all list (gmail, outlook, etc.) still bypassed.
