?? I'm not certain what the question is.  Does the roundcube instance
use the DNS name or the IP address of the IMAP server.

Does "host your-server-name" return the IP of the server?

I'd guess it is a DNS issue [although, in my experience, TB3 is a really
buggy app - so who knows].

If you are on LINUX try it with Evolution [a good IMAP client] - does it
work from there?
