does not work

[goddan]

Hello. I wish to thank developers for an excellent component!!!
 It works for me on 2 sites. But today I have tried to put it on 3 site. But unfortunately I cannot understand in what a problem. The component does not work. I use a component for joomla from http: // //www.joomlaplug.com/Forum/func, view/id, 2704/catid, 15/   - component was established normally any mistakes thus did not arise.

But at me it is impossible to come into viewing mail. I have established a component, mistakes did not arise. In adjustments has put
Auto Create User: true
Default Host:lgbt.az
Default port:143
Username Domain:lgbt.az

I try to come under the reference
http: // //www.lgbt.az/index.php?option=com_roundcube
nothing occurs.
You can try a login: 123 pass:123

Many thanks.

Excuse for my English.
