I do understand Google's challenge with handling probably the largest amount of email traffic in the world, and then the most spam in the world, and that it is a continuously moving target.

But it does feel like they are treating nearly all minor relays as spam relays. We can not block 100% of spam before we relay onwards to Gmail as that would mean too many false positives emails get blocked, but most try to block as much as possible.

In my case, my servers probably block 99% of spam, but some will get relayed, and most of those ends up being handled by Gmail's even better Bayes scoring and filtered to end users' spam folders.

I don't know what the automatic threshold limit is to be on their naughty list, but it must be very low, as in double digits per day.
