[Mimedefang] name= and filename= different

[Joseph Brennan]

Mismatch noticed in Chinese-language spam:

Content-Type: application/vnd.ms-excel;
	name=nfy.xls
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
	filename=vmdgjctvi.xls

I wonder whether name= and filename= being different are diagnostic of 
fakery
or are just something one can expect in mail from normal software. I never 
paid
attention. Before I figure how to parse them out and log them to check-- 
has
anyone gone down this path already?
