That does happen in cases where the retries for a message come from a different IP address than the original delivery attempt. It had slipped my mind (it's been a while since I had it happen), but as you are correctly pointing out there are some sites which are problematic for that reason. For some reason Gmail appears to be a special case - they appear to have their outgoing severs spread thinly over several address ranges, but they tend to get through anyway. Then again, it's likely you end up whitelisting the affected networks once you identify them. -- Peter N. M.
