Good evening, it is able to set somehow RC to us as a domain for new user only domain ? we use imap host (mail_host) "email.domain.cz". user put username for example "johny" as an username, put password in his profile setting in the roundcube he get email setting "johny@email.domain.cz". How do I set "creating" of the email addres for a new users. We must preserve imap host "email.domain.cz", but the user must have set up <user>@domain.cz Thanks and best regards J.Karliak
