OK, but that is the problem: you're relying on google infrastructure
for a service it does incredibly poorly.

Well, to be honest, I find spamassassin to be incredibly useful (it's
what I use), especially being rules and points based instead of
absolute (meaning I can use the RBL but not rely on it). A It hasn't
given me a false positive on anything for over a year and its false
negative rate is about 2% with my current configuration.

However, I think the best solution is to use vger ... it already has an
efficient ingress filter and it doesn't rely on google, so it doesn't
suffer the arbitrary mail loss problem of google.
