Before these ACL checks, have:
warn set acl_m_is_spam = 0

Add to this: set acl_m_is_spam = 1
Hereafter, $acl_m_is_spam is either 1 or 0 and is unaffected by
anything other than your own spam score. You've separated out the
security-sensitive data to a different namespace which can't be directly
added to by the remote untrusted data source.

Note that this is preserving any needed MIME mangling in the original
"Subject:" header by using the raw form. There's a slight risk that the
first line will end up overlong, but it's less wrong than putting
decoded data in.
