Hello, I just installed ispconfig 3.1.2 All has gone well, but I do have a question on the email for the initial test domain. All works well using starttls in thunderbird. Yeah! However, Outlook 2007 gives me an error "The target principal name is incorrect" You can click on view certificate, but thats about it. If you choose continue using this server it works just fine until you reopen outlook, then the irritating message comes up again. BTW, the cert that is viewed is the host name of the main ispconfig server, not the domain I'm using. eg isp.example.com rather than mail.newdomain.com I kinda expected it to use the ssl cert of the new email domain.. ??? Of course I've not idea what I'm doing with this at all.. So I guess the question is, what do I need to do to get outlook to quit complaining..
