Postfix header checks is my friend:

	header_checks = pcre:/etc/postfix/header_checks
	mime_header_checks = $header_checks

The file /etc/postfix/header_checks contains (amongst other filtering rules) 
the following group of lines (white space IS important here):

        REJECT Attachment file type not allowed ("$2" has the extension ".$3")

This will block (almost) all e-mail with (Windows) executable attachments.

Best regards,

PS  I read this mailinglist too, so there is absolutely no reason to CC me as 
well. In fact, I usually ignore traffic to this address NOT from the 
mailinglist server.
