theotherdude When attempting to login for the first time with http://FQDN I get https://FQDN/webmail/ with good certificate but the page is 404 not found. Where to start? I have looked at docker-compose logs -ft nginx-mailcow and everything seems fine there. No proxy in front of this just plain mailcow install no frills. I did have to do this SKIP_HTTP_VERIFICATION=y to get the cert to install. ???
theotherdude Thats interesting. I think you answered my question. SOPHOS firewall may be manipulating things here. Thanks for your reply.
