Yes.  It's still doable, though, if you make calls directly into
the Mail::SpamAssassin modules rather than using the built-in MIMEDefang
code.

If you can group recipients into "equivalence classes" that have the
same SA settings, you can get away with one scan per equivalence class
rather than one per recipient.  This is a fair bit of work.
