[imp] Horde freezes when clicked on "Send Message"

[Michael Gawrychowski]

Hi, I tried to set up horde to use an external smtp server instead of the
local one. I changed the following line in the conf.php file:

$conf['mailer']['params']['host'] = 'ironport06.strongport.com';

and also servers.php:


$servers['imap'] = array(
    'name' => 'IMAP Server',
    'server' => 'localhost',
    'hordeauth' => 'full',
    'protocol' => 'imap/notls',
    'port' => 143,
    'folders' => '',
    'namespace' => 'INBOX.',
    'maildomain' => 'ironport06.strongport.com',
    'smtphost' => 'ironport06.strongport.com',
    'smtpport' => 25,
    'realm' => 'ironport06.strongport.com',
    'preferred' => '',
    'dotfiles' => false,
    'hierarchies' => array()
);




Now, when I click on "Send Message" its loading and loading and nothing
happens. How can I troubleshoot this?


Thank you
