I recently updated mailcow and the server stopped sending and recieving emails. I checked what I could find on the internet, without any results. I know that the emails are not being sent becauase they cannot find a route to host. I have verified by telnet that I do not have access to any of the email ports connected to the server as I recieve a connection refused when trying them, but I do have connection to port 80 and 443. I am able to send and recieve emails within the server (inter domain) but not to external domains. MXtoolbox also alerts that it cannot reach my smtp host.
I have been banging my head for hours trying to resolve this issue, but my limited knowladge of docker and how it works with its routing has me stuck.
I would greatly appreciate any help in solving this problem.
