Or, If you fancied trying the excellent postfix, its as simple as:

-- /usr/local/etc/postfix/block

/^(Content-(Type|Disposition):.*|[[:space:]]*(file)?)name=("[^"]*|{^{:sp
ace:]]*)\.(exe)[[:>:]]/ REJECT


-- /usr/local/etc/postfix/main.cf

Body_checks= regexp:/usr/local/etc/postfix/block

Cheers,
