Our solution was putting some PHP logic in backends.php. Basically, we
populate the backends array comparing the name of the IMAP server where
the user logs with the preferred field of the available backends.

Our configuration looks like this: 

$availableBackends['foo'] = array(
    'driver' => 'null',
    'preferred' => 'foo.company.com',
    'hordeauth' => true,
    'params' => array(),
    'script' => 'imap',
    'scriptparams' => array()

$availableBackends['bar'] = array(
    'driver' => 'timsieved',
    'preferred' => 'bar.company.com',
    'hordeauth' => true,
    'params' => array(...)

$backends['default'] = $availableBackends['foo'];

$currentServer = $GLOBALS['registry']->call('mail/server');

  Selects a backend using 'preferred' field 

foreach ($availableBackends as $temp) {
    if (!empty($temp['preferred'])) {
        if (is_array($temp['preferred'])) {
            foreach ($temp['preferred'] as $val) {
                if ($val == $currentServer) {
                    $backends['default'] = $temp;
         elseif ($temp['preferred'] == $currentServer) {
            $backends['default'] =  $temp;
