[Mailzu-users] IMAP auth problem

[<va...@jo...>]

Hi,
I am trying to get IMAP auth working.
I use CentOS 4.2, dovecote IMAP server is also running on the same 
system (all components of mailzu, amavis, mysql, etc are on the same 
system).
every time I try to log on, I get these messages in 
/var/log/httpd/error_log :

[client 192.168.1.40] PHP Notice:  Undefined index:  domain in 
/var/www/html/mailzu/index.php on line 30, referer: 
http://192.168.1.40/mailzu/
[client 192.168.1.40] PHP Notice:  Undefined variable:  username in 
/var/www/html/mailzu/lib/Auth.class.php on line 218, referer: 
http://192.168.1.40/mailzu/
[client 192.168.1.40] PHP Fatal error:  Call to undefined function:  
imap_open() in /var/www/html/mailzu/lib/IMAPAuth.class.php on line 84, 
referer: http://192.168.1.40/mailzu/

PHP safe mode is off (in php.ini) and corresponding entry in mailzu conf 
is set to 0:
$conf['app']['safeMode'] = 0;

Here are the IMAP auth section and auth type section from conf file:
$conf['auth']['serverType'] = 'imap';

/*** IMAP Authentication Settings ***/
// List of IMAP servers and ports (e.g.: 10.1.1.20:143)
$conf['auth']['imap_hosts'] = array( '127.0.0.1:143' );

$conf['auth']['imap_type'] = 'imap';

// Domain name part of the email address, (e.g.: example.com)
$conf['auth']['imap_domain_name'] = 'actual_domain.actual_tld';


Can anyone please shed some light on this..
