[Exim] ACL to ALLOW only mentioned attachments type and bloc…

Hi,


Currently i'm blocking these attachments.....that came default with vexim2
example configure file...

---
deny  message = This message contains an unwanted file extension
($found_extension) which s7 admin won't like :)
         demime = scr:vbs:bat:lnk:pif:exe
--------

Can i write a ACL which allows only specified attachments type and BLOCKS
all *


By this atleast we don't have to mention all the attachment type what we
want to block....We can just mention what we won't block...

-Dilip
