Hi Community.
I'm new in here and as such I've tried to search the community for a solution before posting. But it is hard to find the right search terms, so I hope you can bare with me.
I have a very fresh installment of ispconfig 3.2.9, and has moved the e-mail accounts from my old server and all is fine. I can send and receive e-mails from outlook, without any problems. All is fine and so I know postfix and dovecot is working as expected.
But with rouncube I have some issues:
I can use the local ip of the server 192.168.0.200/webmail - no problems I can log-in. The inbox and other folders show up with content as if I used outlook as client.
I can use the global ip of the server xxx.xxx.xxx.xxx/webmail - no problems I can log-in. As with the local ip, my folders show and content as well. But it is not secured, so it is not safe.
I can use the servers domain: bnjprio.dk/webmail - but here I can log-in, but folders are present, but no content is shown in any folders. This looks like a DNS problem, but I can't figure out what it could be. I have opened port 53, which I understand is necessary, both in ispconfig and my router.
Is there something obvious I have missed? Any ideas and pointers are appreciated.
