Customer cannot create mailbox
Hey there, I've installed a fresh ispconfig3.1 system. After giving customer unlimited permissions (-1 on mail settings), I cannot create a mailbox after switching to customer. I've installed dovecot + roundcube. Another strange thing is, that I cannot login to the mailbox via imap or roundcube. Any clues where I could begin checking out that problems?
Best regards
PS: info@example.com was created as customer before !increasing! permissions. info@example.de was created as admin user.
