I wonder if we should just reject these messages in lmtpd.

I wouldn't complain. When I was at Morgan Stanley I worked with Victor Duchovny on a MIME canonicalizer. We discovered all _sorts_ of "interesting" MIME and base64 issues. It is possible to create a mail message in such a way that 6 different mail clients will see 6 different attachments. If you realize that your antivirus is just such a client, the security issues quickly become apparent...
