If you -know- that the non-binary part is small/moderate, throw it at
SA anyway. SA is programmed to skip over binary parts and not even try to
scan their contents, so no loss of speed.

Alternatvly front-end SA with a MIME filter such as MIMEDefang to
strip out the binary parts and feed the rest to SA if small enought.
