Greetings all - We're on ISPConfig 3, on Ubuntu 16.04, vhost configuration. During some recent config work on the server, we managed to lose some of the email server config (see pic) The server & ISPConfig seems otherwise ok, except for related mail config issues (i.e., email clients & roundcube won't connect). Suggestions on how we can restore this data? of course, happy to produce any config files requested. Thanks so much!
