Redirect HTTP to HTTPS

Since February the 28th 2017 mailcow does come with port 80 and 443 enabled.

Do not use the config below for reverse proxy setups, please see our reverse proxy guide for this, which includes a redirect from HTTP to HTTPS.

Open mailcow.conf and set HTTP_BIND= - if not already set.

Create a new file data/conf/nginx/redirect.conf and add the following server config to the file:

server {
  root /web;
  listen 80 default_server;
  listen [::]:80 default_server;
  include /etc/nginx/conf.d/server_name.active;
  if ( $request_uri ~* "%0A|%0D" ) { return 403; }
  location ^~ /.well-known/acme-challenge/ {
    allow all;
    default_type "text/plain";
  }
  location / {
    return 301 https://$host$uri$is_args$args;
  }
}

In case you changed the HTTP_BIND parameter, recreate the container:

docker compose (Plugin)docker-compose (Standalone)

docker compose up -d

docker-compose up -d

Otherwise restart Nginx:

docker compose (Plugin)docker-compose (Standalone)

docker compose restart

docker-compose restart
