They are different. In Roundcube, the "ssl://" prefix means "connect 
using SSL immediately," which only works when the server is expecting an 
SSL connection; for example, the Dovecot "imaps" service on port 993.

If I was paying attention in the Dovecot thread, I think you've got 
regular IMAP on port 143, with optional TLS via STARTTLS. Roundcube only 
began supporting STARTTLS with the latest version, 0.2.2. I gather from 
the docs that you would simply change the "ssl://" to "tls://" to get it
