I'd like to reopen this bug, because i did a lot of testing and have some
results that you will find interesting.

First of all: Its not only an Outlook-quoted-printable-bug but also a
IMP-quoted-printable bug.

You said line-breaks like 0x0d 0x0a need to be encoded in quoted-printable
like =0d=0a and since outlook failes here youre not responsible for
modification in attachments.
Hmm... but why is a mail sent by horde with such a file attached encoded the
same *wrong* way like outlook did?

My testing invoved several outlook versions (express, 10, 11), thunderbird
and three horde/imp versions on the client-side and postfix, sendmail and
exchange on server sides. All clients were used under Windows XP - horde/imp
on Firefox and IE.

Thunderbird and the oldest horde/imp installation sent the file
base64-encoded and all other clients chose quoted-printable for encoding the
attached file. Since base64 encoding is not a problem at all no
server-client pair had any problems with these mails.
No Server had any problems at all with any of the other mails and connected
by outlook or thunderbird the files downloaded from that mails where
absolutely fine.
One of the three horde/imp clients had no problem either on receiving the
quoted-printable-attachments, but the two newer horde/imp installations
corrupted the quoted-printable-attachments of any mail received.

OK : Horde 2.2.5 / Imp 3.2.3

Error : Horde 3.0.6 / Imp H3 (4.0.4)
Error : Horde 3.2-cvs / Imp H3 (4.2-cvs)

Now i'm sure that this is really of interest for you since every tested
combination works fine except the two newer horde/imp installations. Even
mails with quoted-printable-attachments sent by one of the newer horde/imp
installations can't be properly saved by either of them - but the older
horde/imp installation works fine with those emails.
Since theres a major version jump between the older and the two newer
versions somewhere in between this "bug" must have been included.

I'm attaching a test-file - please remove if not needed anymore!
