For example, we allow customer service employees to impersonate a customer. This is done through a specific imap server that allows impersonation. But this doesn't work, because roundcube will create a new config entry in the database because the imap server changed. Even though from our point of view, the imap servers deal with the same user base.

Yes, it's probably about time to address this. While there are still
scenarios and setups out there that require the host to uniquely identify a
user, I also understand the problems the current behavior inherits.

First I wanted to solve this automatically (e.g. use mail_host if the
username isn't a fully qualified email address) but that most likely
doesn't cover all cases either. So a config option would be a proper
solution, I guess.

Any objections or other opinions?
