Need some hand holding for reverse proxy

maybl8

I tried to read about the reverse proxy but it seems a little complicated for me and I don’t want to mess up my mail server. It is running just fine.
What I have is one server and one ip address.
I have 2 domain names. One for my mail server and one for a web server.
I would like to run the mail server and the web server on the same physical system.
My understanding is this can be done with reverse proxy.
Can someone help me with step by step on how to set this up?

caylakpenguen This looks easy enough. However my mailcow is installed as a docker container with a docker compose yml already. Can I have 2 of them on one server? The documentation doesn’t explain how to do that.

Its possible, if you are fit in docker and docker compose.

maybl8 The documentation doesn’t explain how to do that.

This is what you need to do on mailcow side. The rest is docker knowhow.

With Lets Encrypt certificates that gets even more complicated…

So this is in my mailcow.conf file
HTTP_PORT=80
HTTP_BIND=

HTTPS_PORT=443
HTTPS_BIND=

You don’t need to change the Nginx site that comes with mailcow: dockerized. mailcow: dockerized trusts the default gateway IP 172.22.1.1 as proxy.

Make sure you change HTTP_BIND and HTTPS_BIND in mailcow.conf to a local address and set the ports accordingly, for example:

HTTP_BIND=127.0.0.1
HTTP_PORT=8080
HTTPS_BIND=127.0.0.1
HTTPS_PORT=8443

So if I change those entries to the above my mailcow will continue to work just like it does now.?
Is this the first step in the reverse proxy procedure?
