[imp] MIME types problems

[John Madden]

Using horde-webmail-1.2.4, I'm experiencing an issue with certain MIME 
types (.dwg files from Autocad) that get attached and sent as text/plain 
rather than their real type.  I've played with the usual /etc/mime.types 
and adding types to Apache's configuration but so far, I've been unable 
to get IMP/DIMP to recognize the file type correctly.  Swinging in the 
dark, I've played with config/mime_drivers.php too.

On the server side, I've duplicated this on Debian 5.0.3 and RHEL 5.4 
with the standard Apache and PHP packages.  Clients Firefox, IE7 and IE8 
on Windows and Firefox on Linux all behave the same.

Any pointers?

Thanks,
   John
