[imp] imp 3.0 - attachments problem - 0x0a being prepended

[Scott Kearney]

I just realized that all screens I can browse in our IMP installation have
linefeeds prepended to them. Since they are all HTML, they work, and I
hadn't noticed. Images DO show up in these pages, so I don't think it is a
web server issue, as the client side GETs on the images succeeds.

I looked into it a bit, and finally figured out that it was due to a few
stray linefeeds at the bottom of horde's registry.php! I edit with emacs,
so I probably hit 'down' one too many times and saved it. Anyway, that's
one fix that was easy enough. Now I can download un-messed up images in
netscape.

However, IE still has the same problems. Still the same "the site is
either unavailable or cannot be found" error. And neither browser can
view the attachments using the filename (as opposed to the diskette icon).
Netscape gives a "The document contained no data" error, and IE just pulls
up a blank window.

I removed the changes I had made based on the following post:
