[exim] Blocking attachments missing file extension

There is currently a virus attack based on attachments missing file extensions..

So instead of virus.zip or virus.exe - the file name is just virus.




I was looking into regex to match that - may not be trivial?

I'm also thinking a better way would be to block all attachments that don't have an approved
extension? I think someone must have gone down this path before - but searches are not getting me
there..
