Mailinabox behind mikrotik router

It has to do with running your box behind a router. I had been running my server for almost a year with the same errors you have until I had this reply on my thread.

Btw. If you are hosting your server yourself on a private network you don’t have to have ssh access. I have a vpn that connects to the network I’m hosting my server on so I disabled public ssh access for added security, I just ignore the ssh error on the status checks page.
