[Mimedefang] layout of text-only messages changes when modified my mimedefang (outlook)

[Martin Bene]

Hi,

I'm just trying to upgrade from mimedefang 2.8 to 2.16; there's one strange
effect that I see after the upgrade: if mimedefang changes a text-only
message (either inline or as a seperate mime entity) by removing an
attachment and adding the warning message, the original mail will have its
linefeeds doubled - there's an empty line after each line of text.

sample (mimedefang message is in german, it's the usual "WARNING, this
message has been ...."):

------------snip---------------
This is a test message

that was 4 lines long originaly and had eicar.com as an attachment

after mimedefang, there's four aditional

empty lines - where do they come from?

As stated, the same thing happens when adding the warning as a seperate mime
part (warning.txt), the original message still arrives with double
linespacing.

I'm seeing this weird effekt on outlook 2000 on Win XP.
Thanks for any hints, 

Martin
