[imp] attachment changes after sent with imp

[Philip Steeman]

Hello,
I have an attachment, a labview-file  (see 
http://users.khbo.be/steeman/clock.vi).
When I sent this with imp as a attachment, and I save it with imp it is 
changed!!
I think it is the same problem as the unicode problem.

Isn't it possible to encode ALL text-attachments in base64? The only 
sollution we currently advice our students is to zip all this kind of 
files before sending it to the teachers.

For other attachments (.rdp, .sav) the problem only existed when the 
mail was sent with imp and read with thunderbird/Outlook. It was OK when 
read with imp.
Now with this .vi file, the file isn't even usable anymore when sent 
with imp AND read wiith imp.


Versions:
horde 3.1.7
imp 4.1.6
