I finally had time to do a little bit research about the problem. There are
two parts about this.

1. If user has't for example Office application installed and tries to
send document attachment it gets sent as text/plain. This is normal
because browser doesn't know file type and sends application/octet-stream.
IE6, IE7, FF1.5 and FF2 behaves exactly this way. Only Opera 9.1 has
builtin MIME detection for my tested Word Document Type. This means that
you can't rely on user client/OS.

2. If you can't rely on user client/OS configuration then it means that
your server must be presicly configured to give Horde the right mime type.
However I tested 3 different installations of Fedora Core 5, RedHat
Enterprise 4 and RedHat Enterprise 5 beta 2. None of them detected correct
mime type with default installation. Even with fileinfo PECL module
installed they still reported text/plain. And with only some hacking
through config files I found this ->

   Seems like most of the office documents was dissabled by default in
vanilla apache since 1998! This means that very large base of UNIX type
OS'es that uses vanilla apache is affected by the problem most probably
too.

Now back to the point. I know that it is faster to send plain text
attachments and plain text, and wiser used space way, and I agree with you
that having possibility to read those attachments in console programs is
good. BUT, for the sake of large user base without office installed and
for the sake of large admin base with vanilla apache configuration, PLEASE
revert IMP to encode all text/plain attachments with base64 again.
