Just a wild guess based on experience - do those deliveries happen over IPv6? I've seen similar when delivery was attempted from an IPv6 address without proper reverse lookup. At the time (some years back) it looked to me at least that Google had decided to be quite a bit stricter in handling mail from IPv6 space than from IPv4. All the best, Peter -- Peter N. M.
