That's a very good point, and in fact it could explain some
false rule firings (of FUZZY_OCR_CORRUPT_IMG) that I've seen,
although it's hard to know for sure.

If the closest MIME boundary thing turns out to be prohibitively
difficult, another idea is to just have a flag for tests
that indicates whether the test should be run if the message
was truncated.  Of course, that might require changes to both
SpamAssassin and Mailscanner, so maybe not that easy...
