For a user to not need to know what backend his/her mailbox is actually 
on, one would typically point the web client to a frontend IMAP server - 
however this is only applicable to actual murder topologies.

This will also eliminate the need for the user to use a specific backend 
host when connecting with another client (like Kontact) as well.

Other methods include NGINX IMAP proxies, along with a little bit of a 
PHP script.

That said, there's no way for Roundcube to automatically, autonomously 
and disjunct from other clients, figure out what server a user's mailbox 
may be on.
