I have update my backends.local.php:

  $servers['imap']['name'] = 'IMAP Server';
  $servers['imap']['disabled'] = false;
  $servers['imap']['hostspec'] = 'imap.dcs.bbk.ac.uk';
  $servers['imap']['hordeauth'] = true;
  $servers['imap']['tls'] = 'tls';
  $servers['imap']['maildomain'] = 'dcs.bbk.ac.uk';
  $servers['imap']['smtp'] = array (
         'horde_auth' => false,
         'debug' => 'true',
         'lmtp' => false
  );
  $servers['imap']['acl'] = false;
  $servers['imap']['debug'] = '/tmp/imp.log';
  $servers['advanced']['capability_ignore'] = array('ESEARCH');

but then I notice errors in the web server logs:

PHP Fatal error:  Only variables can be passed by reference in 
/var/php/5.3/pear/Horde/Idna.php on line 42, referer: 
https://webmail.dcs.bbk.ac.uk/webmail/imp/dynamic.php?page=mailbox

which refers to the lines:

case 'INTL_UTS46':
             return idn_to_ascii($data, 0, INTL_IDNA_VARIANT_UTS46);


and then later on it fails to find Class 'Horde_Idna' since the above error.

PHP Fatal error:  Class 'Horde_Idna' not found in 
/var/php/5.3/pear/Horde/Mail/Rfc822/Address.php on line 96, referer: 
https://webmail.dcs.bbk.ac.uk/webmail/imp/dynamic.php?page=mailbox

I wonder if it is a compatible problem:
$ /usr/php/5.3/bin/pecl -V
PEAR Version: 1.9.5
PHP Version: 5.3.29
Zend Engine Version: 2.3.0
Running on: SunOS webmail-master 5.11 11.2 i86pc
