hi there!

i have successfully (seems to be only partly) installed open-xchange.

i can also setup simply mailboxes via the gui interface... there are a few thing i cannot use - like email-alias and the autorepsonder.. the errormessage always coming up is following message on the webpage:
Error code: com.openexchange.admin.plugins.PluginException: com.openexchange.admin.rmi.exceptions.OXUserIMAPEx ception: javax.mail.MessagingException: Connection refused; nested exception is: java.net.ConnectException: Connection refused

in the detail log i can find:
