Which is essentially the same as I have. As far as I can see there is no
difference between 4.83-5 and 4.84-1 that would affect this.

I am not seeing this.

Or it is a MS-Word .docx file named as .doc.  I don't see what you see
in this case. If I have such a document and manually run antiword on it,
antiword says "xxx.doc is not a Word Document." and returns exit status
1. If I attach the file to an email and send it through MailScanner,
MailScanner does not alter the original attachment.

What is your setting for 'Antiword' in MailScanner.conf or
MailScanner/conf.d/*? Is it different from the default

Antiword = /usr/bin/antiword -f

If not, I don't know why this doesn't work for you as it does for me.
Maybe it's a perl module difference?
