[imp] Empty mailbox

[Peter Paul Elfferich]

Hey all,

I've just done a clean install from the latest nightly snapshot.
Most things seem to be working allright but I've got a serious problem:
When I look at a folder in IMP, I don't see any emails listed there, even 
though the map listing shows (correctly) that there are messages in my INBOX. 
And authorisation using the same IMAP server works fine as well.

When I looked at the log files, I noticed the following in my Courier IMAP 
server log:
Mar 18 03:39:06 lo1 imaplogin: Connection, ip=[::ffff:145.18.147.22]
Mar 18 03:39:06 lo1 imaplogin: LOGIN, user=pp, ip=[::ffff:145.18.147.22]
Mar 18 03:39:07 lo1 imaplogin: LOGOUT, user=pp, ip=[::ffff:145.18.147.22], 
headers=0, body=0

With an older stable install the same action results in this log message:
Mar 18 03:40:37 lo1 imaplogin: Connection, ip=[::ffff:145.18.147.21]
Mar 18 03:40:37 lo1 imaplogin: LOGIN, user=pp, ip=[::ffff:145.18.147.21]
Mar 18 03:40:37 lo1 imaplogin: LOGOUT, user=pp, ip=[::ffff:145.18.147.21], 
headers=70, body=0

Notice the headers=0 generated by my new install.
Other log files don't show anything out of the ordinary.

The old stable working install is running on one server (Debian stable), 
together with the Courier IMAP server. The new install is running on another 
server (Debian unstable) using it's own database server but using the same IMAP 
server for authentication and reading email. The Horde test.php doesn't give 
any errors except for the lack of OpenSSL support which I don't need.

Here's my IMP server configuration:
$servers['imap'] = array(
    'name' => 'LO1',
    'server' => 'lo1.dia.uva.nl',
    'protocol' => 'imap/notls',
    'port' => 143,
    'folders' => 'INBOX.',
    'namespace' => '',
    'maildomain' => 'dia.uva.nl',
    'smtphost' => 'lo1.dia.uva.nl',
    'realm' => '',
    'preferred' => '',
    'dotfiles' => false,
    'hierarchies' => array());

Does anybody have any idea what's the problem here?

Any help would be much appreciated!
