This has been a sporadic issue for me that seems to be getting worse. Previously the missing messages were primarily from Yahoo addresses and getting incorrectly marked as spam for what appeared to be SPF reasons. This is a Google header parsing/spam routing bug (even if you have rules to deliver these messages anyway!) and I still have to go retrieve those periodically although less often lately. Currently some replies are being delivered hours or days before the originating message. Sometimes the originating message is not delivered at all. I'd have to see John's MTA logs to know why but as someone whose professional responsibilities include deliverability of messages with rewritten headers I've seen comparable problems when the receiving MTA is greylisting delivery attempts due to bad heuristics. Both you and I are using Google mail infrastructure so that might be the commonality to start pointing fingers.
