I'm the sender, not the receiver. The mailserver uses two resolvers, BIND and Unbound. BIND returned SERVFAIL while Unbound still served a "validated" answer. Both should have cached the answer earlier, as there's a constant flow of mail towards mixmin.net from here. I don't know if it had already expired from BIND's cache, though. Hauke.
