If you searched qmail-scanner-queue.pl, you'd see that "Disallowed MIME
Content" only shows up once. It means someone sent a mail message that:

a> claims to be MIME (by the presence of a "MIME-Version" header)
b> has a "Content-Type" header that is NOT in the RFC-prescribed format
of "XXX/YYY" (e.g. "text/plain")

As such Qmail-Scanner tags it as broken and quarantines it.

Sounds like a broken mailer in action to me...
