Meh, I drank more coffee. You're already producing backscatter.

I'm happy that you've now improved your situation, but please do look at
moving the checking into ACL-time checks to avoid this. You should be
able to use per-user spam-scanning with an ACL just fine. When you use
the spam condition, you write

spam = ${something that expands to the user that SpamAssassin should use}

Please read over "41. CONTENT SCANNING AT ACL TIME" in The Exim
Specification.
