OBJECT
Sender addresses that never start a run, with '' as a wildcard anywhere: ‘noreply@stripe.com’ (exact), ‘@agoda.com’ (whole domain), ‘@.agoda.com’ (its subdomains), ‘badr@-ops.com’ (any middle part). Case-insensitive, matched against the full sender address. Seeded with the machine-sender patterns (noreply@, mailer-daemon@*, …); remove any of them to let that class of mail through.
