Thank you very much.
no problem
I changed $config['identities_level'] in /usr/share/nginx/roundcube/config/config.inc.php to 0. Now I'm able to change the e-mail address for a new identity.
good, glad it was simple, but keep in mind that sasl user login is still exposed in headers when mail sending, should not be a problem, but there is always spammers that prefer no mailbox at all :=)
