[Michel Vega Fuenzalida]

Sorry my english:

I have Horde Groupware Webmail Edition 1.0.7 and like Mail Server a
MDaemon Server 9.6.1 in Windows 2003 Server. When i use
horde/imp/test.php, it said:

PHP Mail Server Support Test
Attempting to automatically determine the correct connection parameters
for your server:

          ERROR - The server returned the following error message:

The 143 port is open, I can make: telnet ip.mdaemon.server.cu 143.

Some body can help me.

It's my imp/config/server.php:
$servers['imap'] = array(
    'name' => 'MDaemon IMP Server',
    'server' => 'x.y.z.b',
    'hordeauth' => false,
    'protocol' => 'imap/notls',
    'port' => 143,
    'maildomain' => 'my.domain.cu',
    'smtphost' => 'x.y.z.a',
    'smtpport'=> 25,
    'realm' => '',
    'preferred' => '',
);
