[imp] missing messages IMP 4

[Tracy L Skaggs]

I'm having difficulty with the latest IMP/Horde and an Exchange server.

Here is the version information on the Linux (Mandrake 10.0 official)
side

horde-3.0
imp-h3-4.0.1
Apache 2.0.47
php-4.3.0

The Windows side is a simple Exchange server 2000 on Windows 2000 server
SP4

I am still using Horde 2.2.5 and IMP 3.2.3 on the same Linux box without
any issues.

What is happening with IMP is it is properly detecting the number of
unread messages on the Exchange server and the number of total messages
in the INBOX but also says "There are no messages in this mailbox." and
doesn't show any message detail lines.  I n modify the sources.php on
the IMP 4 install to point to a local Courier IMAP server and the INBOX
displays messages as expected.

Here is the servers.php entry for the Exchange server from the latest
IMP:
$servers['exchange'] = array(
    'name' => 'Exchange server',
    'server' => 'CHANGED FOR SECURITY',
    'hordeauth' => false,
    'protocol' => 'imap/notls',
    'port' => 143,
    'folders' => '',
    'namespace' => '',
    'maildomain' => 'CHANGED FOR SECURITY',
    'smtphost' => 'localhost',
    'realm' => '',
    'preferred' => '',
    'dotfiles' => false,
    'hierarchies' => array()
);

Here is the servers.php entry for the previous IMP:
$servers['imap'] = array(
    'name' => 'Exchange Server',
    'server' => 'CHANGED for SECURITY',
    'protocol' => 'imap/notls',
    'port' => 143,
    'folders' => '',
    'namespace' => '',
    'maildomain' => 'CHANGED FOR SECURITY',
    'smtphost' => 'localhost',
    'realm' => '',
    'preferred' => ''
);

Here is the output of an IMP test from the test.php script:
