[imp] attached excel or powerpoint files get application/msword as mime type

[Yves Bilgeri]

Hi,

I'm using Horde3.0.4, IMP4.02 on a Debian/Sarge Server with
the official packages from Debian.

My question is exactly the same as:
   http://marc.theaimsgroup.com/?l=imp&m=110798353021570&w=2

Because there isn't a real answer in the thread above, I kindly ask the 
same again.

The problem is, if I attach an Excel (or PowerPoint) document in IMP 
then it recognise it as application/msword. If I send the message this 
way, then the mime header for this part looks like this:

Content-Type: application/msword;
	name="test-01.xls"
Content-Disposition: attachment;
	filename="test-01.xls"
Content-Transfer-Encoding: base64


If the recipient then opens the message in IMP, he gets confused of the 
msword icon and he has to download the attachment to open it correctly.
Or if he uses Thunderbird he has to save these attachments before he can 
  view them what's a bit cumbersome.


Did I miss somthing in the config? Or do I need an extra app on the 
server to differ the different MS Office files?

Thanks in advance,
Yves
