Some messages contain information at the top about the MIME parts, see the
sample at the end for an example. This causes message previews to display
this ugly text instead of the start of the actual message.

A partial fix/hack is to remove the MIME info from the preview with a regex.
In horde/imp/lib/Mailbox.php, after line
294: $ptext = trim(strip_tags(@imap_fetchbody($imp['stream'],
$header->msgno, 1)));
insert the line
$ptext = preg_replace('/^.*Content\-Transfer\-Encoding\:.*?\n/s', '',
$ptext, 1);

This only works if the first message part, that imap_fetchbody fetches is
the plain text part. If it is an attachment or something then we can never
get the text from it. To handle all situations, we'd have to add in some
code to make sure we fetch the plain-text part of the message (if there is
one of course) to use for the preview.
