Hello, Thank you for a really useful guide! I'm wondering what changes would be needed to use ViMbAdmin(PostfixAdmin replacement) to administrate mail server created in this guide? On https://github.com/opensolutions/ViMbAdmin/wiki/Postfix-and-MySQL-Integration I've found general instructions for the integration. I suppose in ViMbAdmin integration guide that mail store is Maildir or mbox, not the mysql database. Correct? Finally, is ISPConfig3 better solution than ViMbAdmin in this case?
