[horde] Still error when communicating with the server...

[Michael Christopher Robinson]

[root at web config]# cat backends.local.php 
<?php
$servers['imap'] = array(
    'disabled' => false,
    'name' => 'Goose IMAP server',
    'hostspec' => 'mail.robinson-west.com',
    'hordeauth' => full,
    'protocol' => 'imap',
    'port' => 143,
    'secure' => 'tls',
);
[root at web config]# 

Tail end of current conf.php:
...
$conf['imap']['server'] = 'localhost';
$conf['imap']['port'] = 143;
$conf['imap']['secure'] = 'tls';
$conf['imap']['maildomain'] = 'robinson-west.com';
$conf['imap']['cache_folders'] = false;
$conf['imap']['enabled'] = false;
$conf['imsp']['enabled'] = false;
$conf['kolab']['enabled'] = false;
$conf['hashtable']['driver'] = 'none';
$conf['activesync']['enabled'] = false;
/* CONFIG END. DO NOT CHANGE ANYTHING IN OR BEFORE THIS LINE. */

I tried to up the logging on the dovecot side, no dice.

There is nothing meaningful in horde.log.

If the problem is the imap server, what is wrong with my current
backends.local.php?
