Translations:Complete Virtual Mail Server/Web Access/5/en

Here there are several options available. Use a local, per vhost based SQLite storage pool, use a postgres/mysql database per vhost or have all vhosts share the same database. There can be advantages for any of the above options. If webmail, for various domains, is on the same host as the imap server, then using one database for all domains is fine and can be an advantage. It could be desired that each domain, each vhost gets its own webmail interface (different skin and plugins) where all users could still log in. Meaning in the event of one of the vhosts webmail being broken, they can still access their e-mail normally using a different vhost. Whether the users settings 'live' in all vhosts or not, is based on the imap server. Roundcube bases its user id on the  e.g. the imap server and thus when using localhost the user 'profile' is identical everywhere.
