Is it possible to route a certain domain to a service running outside of coolify?

[Nubebuster]

I want to host mailcow on the same server as coolify is running. I am running into the issue that I don't know how I can configure coolify to forward mail.my-domain.net to the mailcow container.

Mailcow was previously running on another server and with nginx traffic was routed using the following configuration:

/etc/nginx/sites-available/mail.my-domain.net

server {
    listen 80;
    server_name mail.my-domain.net;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl http2;
    server_name mail.my-domain.net;

    ssl_certificate /etc/letsencrypt/live/mail.my-domain.net/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/mail.my-domain.net/privkey.pem;

    location / {
        proxy_pass https://localhost:8443; # Reverse proxy to Mailcow HTTPS
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

# irrelevant settings omitted

HTTPS_PORT=8443
HTTPS_BIND=127.0.0.1

Since I am unable to get mailcow to run as a docker-compose project in coolify I run mailcow on the host server. This is due to lack of documentation and my lack of understanding of coolify.

To make things simple I thought maybe I can get coolify traefik proxy to forward the mail subdomain to the ports 8080 and 8443 and then let mailcow handle the rest.

Is this possible and feasible?
