[Mimedefang] MIMEDEFANG 2.56

[jean-marc pouchoulon]

Hello, 

I recently upgraded from mimdefang 2.54 to mimedefang 2.56 and since this I received several messages from 
mimedefang that I never seen at such rate ( 6/8 per day):

A MULTIPART attachment of type message/rfc822, named STAGE : Patch 430.exe was dropped.
A MULTIPART attachment of type message/rfc822, named Envoi d'un message : sconet.ini was dropped.

These files are comming from a safe internal source.

is there is any  modifications in filter_multipart ? 

I had also upgraded to :

MIME-Base64-3.03
MIME-tools-5.419

thanks for your advices.
