Exim conditions for attachments

["Craig Schneider" <craigsc@zdata.co.za>]

Hi Guys

I have wrtten a condition to check if a user is in a flat text file, if
so then allow them NOT to receive attachments of a certain type. However
I need to put a condition in to allow them to receive from the
$local_domain.

Heres what I have so far:

#  deny  message = User is unable to recieve attachments of this nature
($found_extension)
#
condition=${lookup{$recipients}lsearch{/etc/mail/extensions}{1}{0}}
#        demime = jpg:mpg:mpeg:mp3:gif:bmp

Any help would be appreciated.

Thanks
