Mailcow UI in subdomain

discartMC

Hi,

I’m trying to do the following (everything is running on a single server):

mydomain.com -> Go to a simple static page (not working - goes to mailcow UI)
mail.mydomain.com -> Go to mailcow UI page (working)
webmail.mydomain.com -> Go to SoGo page (working)

For such a simple setup I would like to keep using mailcow’s included nginx to do this (so I don’t have to worry about certificates and other things - also because it seems wasteful to run another server just because of a simple static page), but I don’t see a way of doing this without changing site-defaults.conf or some other default config in mailcow which I would rather avoid to prevent conflicts in future mailcow updates. It seems I can create a site.*.custom file to extend site.conf, but I don’t know which config I should include in that to archive my static page in mydomain.com goal.

Can anyone point me in the right direction? Thanks in advance

I figured it out. If anyone is interested, just create a conf file in data/conf/nginx with the following content:

server {
ssl_certificate /etc/ssl/mail/cert.pem;
ssl_certificate_key /etc/ssl/mail/key.pem;
index index.html;
client_max_body_size 0;
root /web;
include /etc/nginx/conf.d/listen_plain.active;
include /etc/nginx/conf.d/listen_ssl.active;
server_name visum.pt;

location ^~ /.well-known/acme-challenge/ {
allow all;
default_type “text/plain”;
}

location / {
root /web;
}
}

Then add the index.html to data/web
Don’t forget to add your domain to ADDITIONAL_SAN (https://mailcow.github.io/mailcow-dockerized-docs/firststeps-ssl/) to have proper SSL
