You didn't configure SA correctly. Did you read its documentation?

That does not result in lost mail, just delayed mail.

You complain about false positives?
Well, setup sa-exim to not reject mail before an SA score of 10 or 12. That
will give you very very few false positives.
That said, SA isn't set and forget for an ISP, you have to prepare yourself
to be very familiar with SA and to know how to tweak its scores.
Please send followups to the sa-talk or sa-exim lists.
